Did you know that music is based on natural "laws"?

Did you know that music is based on natural "laws" -- like gravity -- and by learning to understand how those natural laws work we can actually understand what we are doing when we play -- we don't have to be at the mercy of what someone else has written on a piece of music.

How many of these facts do you know about music & piano playing? Test yourself and then check the answers at the bottom of the page:

Did you know that by learning just 3 chords you can play hundreds of songs?

Did you know that there are only 12 major keys you can play in, but you only really have to master one key to play most popular songs?

Did you know that it is possible to easily match any melody note (tune) to a chord, so you can harmonize any note?

Did you know that Beethoven's Fur Elise and the blues song "Summertime" uses the exact same chords for the theme of the song?

Did you know that it is quite possible to predict what chord comes next in a song with accuracy approaching 85%?

Did you know you can use the same chords to play boogie, blues, new age, gospel, pop, rock, jazz, country - anything except classical music? (And even some classics!)

Did you know that by coming in through the backdoor of piano playing -- chords -- you can start making wonderful and satisfying sounds on the piano in just a few days instead of a few years -- even if you don't know Middle C from Tweedle Dee?

The Blues Scale & It's Use

The Blues Scale

The blues started not as a piano style, but as a vocal style, and of course the human voice can sing "in the cracks" between the notes on the keyboard. So when we play blues on the keyboard, we try to imitate the human voice by playing BOTH the 3rd and the flat 3rd -- BOTH the 5th and the flat 5th -- BOTH the 7th and the flat 7th. We would play in the cracks if we could, but we can't, so we do the best we can by combining the intervals to imitate the quarter steps that a human voice can sing. (Certain instruments can do that too -- for example, the trombone. Since it has a slide, it can hit an infinite number of tones between any two keyboard notes.)

So in the key of C, for example, the blues scale would include:

C, D, Eb, E, F, Gb, G, A, Bb, B, and the octave C.
In the key of F the blues scale would include:
F, G, Ab, A, Bb, Cb, C, D, Eb, E, and the octave F.
In the key of G the blues scale would include:
G, A, Bb, B, C, Db, D, E, F, F#, and the octave G.

So in improvising you can craft a melody out of any or all of these notes. Start by creating a motif out of just 3 or 4 notes, then repeat that motif as you change chords.

For example, if you were in the Key of C, you might create a motif such as C, C, G, Bb C and repeat it in various rhythms as you play the C7 chord in your left hand, then again as you move to the F7 chord, and so on.

With practice and experimentation you can play your own variety of the blues as you master the blues scale.

Music Notes: How Pitch & Duration Are Determined

Music Notes: How Pitch & Duration Are Determined

Notes are the musical notation representing a fixed pitch. While the word strictly refers to the physical notation of a pitch, it's more commonly used to refer to both the pitch and the notation.

Piano Lessons: Make Sure They Include Chords & Music Theory!

Piano Lessons: Make Sure They Include
Chords & Music Theory!

Proper piano instruction is an element extremely vital to learning the instrument well. Though it's very possible to be a self-taught piano player, piano lessons can really increase the speed and efficiency with which one learns the instrument. That's not to say that great piano instruction makes great piano players overnight; even the most naturally talented pianists still play for years before they consider themselves advanced. But proper piano lesson instructions will maximize those years to the fullest and ensure that the student is learning the correct techniques.
Though teaching styles always vary from instructor to instructor, piano instruction generally covers the same basic areas: fingering, , music reading, scales, technique, and sight reading. The early lessons will cover fingering and posture, making sure the student knows how to hold his or her hands and where to put them on the keys; series of scales practiced repeatedly will be the basis of this area. Piano instruction will then move on to notation essentials, starting with the basics of notes and key signatures and time signatures and then moving forward to more advanced concepts in rhythm, tempo and dynamics.
Many of these concepts are introduced into the piano instruction while the student is learning to read music, a practice that runs through the entire course of the piano instruction. Teachers will assign short, easy pieces to kick start the student's music reading knowledge and eventually move forward to more advanced pieces. Sight reading, the ability to play a piece of music without ever having seen it, is sometimes placed sporadically throughout the piano instruction, after a student is fairly well-versed in reading music.
One crucial element of piano playing that is often left out of traditional piano lessons is the study and practice of chords and music theory. To learn to read music without understanding the theory behind the music and the chords and chord progressions that form the music is almost like teaching a surgeon to cut without understanding the human anatomy and it's interrelated parts. The student will be able to play the piano from a piece of sheet music, but take that music away or have it blow off the piano and he or she is immediately in big trouble.

Transposition and Modulation

How do transposition and modulation relate? Are they the same? In this newsletter we're going to take a look at both of them and see what makes them tick.

I'm sure that you have had the experience sometime in your piano-playing life when someone asks you to play a song -- but in a different key than in which it is written. It might be a singer wanting you to lower the song a step so he/she doesn't screech. It might be a song leader wanting you to play a song in a more comfortable keys for a congregation or group. It might be a trumpet player looking over your shoulder and wanting to play along with you -- but when he/she plays the same note you are playing, it sure doesn't sound the same!

So....it's your job, as pianist, to get that song moved to a different key. That's transposition -- playing or writing a song in a different key than in which it was originally written.

Modulation is similar but different -- modulation means the process of getting fro
m the old key to the new key. In other words, if I'm playing in the key of C, and then want to play in the key of Eb, I have to learn to modulate -- move smoothly from one key to another without being too abrupt and jarring.

There are basicly 3 ways to transpose:

1. by intervals
2. by scale degrees
3. by solfege -- the moveable "do" system.

But since solfege applies mostly to singers, we will ignore that possibility and just take up the first two:

1. Intervals: If the new key is an interval of a minor 3rd above the old key, then all notes in the song will also be an interval of a minor 3rd higher. In other words, if you are transposing from the key of C to the key of Eb, which is a minor 3rd higher (or major 6th lower -- whichever way you want to look at it), then all melody notes will also be a minor 3rd higher:

"G" in the key of C would become "Bb" in the key of Eb. "E" in the key of C would become ":G" in the new key of Eb. "A" would become "C", "B" would become "D", and so on. All chords would also move a minor 3rd higher. The "C chord" would become the "Eb chord", the "F chord" would become the "Ab chord", and so on.

2. Scale degrees: Each key you play in has it's own scale degrees. In the key of C the scale degrees are: C=1, D=2, E=3, F=4, G=5, A=6, B=7, C=8. In the key of Eb, however, Eb=1, F=2, G=3, Ab=4, Bb=5, C=6, D=7, Eb=8. So if I want to transpose Silent Night, for example, from the key of C to the key of Eb, I need to notice what scale degrees I am using in the key of C, and then use those same scale degrees in the key of Eb. For example, Silent Night starts on the 5th degree of the scale, goes up to the 6th, back to the 5th, then down to the 3rd. In the key of C that is: G-A-G-E. But in the key of Eb it is Bb-C-Bb-G. Why? Because the scale degrees 5-6-5-3 are constant -- we just need to apply them in each key. What about chords? Same idea. If the chord progression on Silent Night is the I chord followed by the V chord, followed by the I chord, followed by the IV chord, etc. -- then in the key of C that means C-G-C-F-etc., but in the key of Eb it means Eb-Bb-Eb-Ab-etc.

Modulation means getting between keys, so let's say you are playing in the key of C, but you want to get to the key of Eb smoothly, without jarring the nerves of the listeners. There are lots of ways to do it, but the main point is that you have to get to the V7 chord of the new key. So from the key of C to the key of Eb, that means getting to Bb7. How do we do that smoothly? We look for chords with common notes. Since the V of the V of the new key would be Fm7, we have C as a common note. So we hold the C in the C chord, and move the rest of the C chord to Fm7, then Bb7, then Eb, and presto -- we are there! I realize that may be a bit hard to follow with just printed words to follow, but if you saw it happen (like on a video) you would understand it instantly, I think.

How To Tell What Major Key A Song Is In Quickly & Easily

Key signatures are a type of musical notation that indicate which key the song is to be played in. But key signatures, despite the name, are not the same thing as key. Key signatures are simply notational devices; just as a note is the notational name for a pitch, key signatures are the notational names for keys. It is what it says it is: a signature, a simple piece of information that tips you off to the physical form (the key) to be played.

What does it mean to be "in the key of F", or "in the key of Bb"?

It means that the composer based the composition on the scale of F (which has 1 flat in it), or the scale of Bb (which has 2 flats in it).

Key signatures appear right after the clef (before the time signature) and show a sharp or flat on the line or space corresponding to the note to be altered. Key signatures placed at the beginning of songs will carry through the entire song, unless other key signatures are noted after a double bar, canceling out the first. For instance, it's entirely possible to start a song in the key of F but end it in the key of E flat; it all depends on the key signatures and where they're placed throughout the song (a key signature can change at any point). Accidentals can also show up throughout a song and only once or twice flatten or sharpen a note that was not previously indicated; this cancels out the key signatures, as well, but only temporarily, for as long as the accidental lasts.

Beginners just learning to read music often have a hard time with key signatures because the key itself is not expressly written, and it's sometimes difficult to remember what goes where.
Key signatures with five flats or sharps have been known to terrorize new musicians -- how in the world, they think, are we supposed to remember all these note changes while we're playing the song? It's obviously possible, though, and there are some rules that can help beginners identify and remember the key as it relates to the key signatures, rules that go beyond rote memorization. If there is more than one flat, the key is the note on the second to last flat. If there are any sharps at all, the key is a half step up from the last one noted. F major, a key frequently found in beginning sheet music, only has one flat (B), and C major has no sharps or flats at all. Key signatures, when viewed in light of these rules, are much easier for beginners to digest, ensuring that a proper knowledge of key signatures is on its way through the door.
One fact that most people don't realize is that sharps and flats always occur in the same order:

The order of the flats is B, E, A, D, G, C, F.

The order of the sharps is just the opposite -- F, C, G, D, A, E, B.

So if there is one flat in the key signature, it is always B. If there are two flats in the key signature, they are always B and E. Three flats are always B, E, and A. Four flats in a key signature spell the word BEAD. And so on.

It's the same in sharps, too, except backward. If there is one sharp in a key signature, it is always F. Two sharps in a key signature are always F and C. Three are F, C, and G. And so on.
So once you have memorized the order of the flats, all you have to do is apply the rule mentioned earlier: the next to the last flat is the name of the key. For example, if you have four flats in a key signature, they are Bb, Eb, Ab, Db. The last flat is D, so the next to the last flat is A. So the key is Ab.

With sharps, just mentally go up 1/2 step from the last sharp, and that is the key. For example, if a key has 4 sharps, they are F#, C#, G#, D#. One-half step above D# is E, so the key is E.
Memorize the order of the flats and sharps and those two simple rules, and you'll be able to identify what major key any song is in quickly and easily. (Minor keys are just as easy, but beyond the scope of this article.)

How To Color Without Crayons: Adding Color Tones To a Chord

How To Color Without Crayons: Adding Color Tones To a Chord

http://www.playpiano.com/Articles/23-colortones.htm

Adding color tones to a chord is like adding colors to a black and white drawing; it adds depth and dimension and well as bringing it to life.

There is a time and place, of course, for "black and white" music, just as there is in art. And many times as a musician I choose to use shades of grey to color my improvisations on the piano, just as an artist uses light and dark to create the feeling and mood of the sketch.

But there are also times when adding a splash of color can do wonders for your piano playing (or guitar or electronic keyboard or organ or whatever). These musical colors create nuances of texture and feeling that are just not available using shades of grey.

So what colors are available from your musical palate? And how do we blend them in to the existing framework of a song?

I'm glad you asked, because you will be astounded at the number of combinations or color tones that can be blended together into any given chord.

First, though, lets review what a basic black and white chord is made of. Every basic triad is composed of 3 notes: a root (the lowest note of the chord), a 3rd, and a 5th.

A major triad consists of a root, then the 3rd note of the major scale, then the 5th note of a major scale. For example in the key of C the major triad is C, E, and G. In the key of D the major triad is D, F#, and A. Why the F#? Because in the scale of D F# is the 3rd degree. So in the key of Db the major triad is Db, F, and Ab. Why the Ab? Because it is the 5th note in the scale of Db.

A minor triad consists of a root, a 3rd lowered one-half step, and a 5th of the major scale. So instead of E as the 3rd of the chord we use Eb. In the key of D, instead of F# being the 3rd we use F, since it is 1/2 step lower than F#.

An augmented triad consists of a root, a 3rd, and a 5th raised one-half step. So the C augmented triad would be C, E, and G#.

A diminished triad consists of a root, a 3rd lowered one-half step, and a 5th lowered one-half step. So the C diminished triad would be C, Eb, and Gb.

Those are the "black and white" chords: no color, but appropriate in most instances.
But when you want to add a flair of creativity to your playing, here is the color palate you have to work with:

2nds: the 2nd note of a major scale.
6ths: the 6th note of a major scale.
major 7ths: the 7th note of a major scale.
7ths: (also known as dominant 7ths): the lowered 7th of a major scale.
9ths: the 9th note of the major scale (same as the 2nd note except an octave higher). If you're wondering why the 9th is not just called the 2nd, it's because the 9th is combined with other color tones, whereas the 2nd is not.
Flat 9ths: the 9th note of a major scale lowered one-half step.
11ths: the 11th note of a major scale (same as the 4th except an octave higher).
Sharp 11th: the 11th note of a major scale raised one-half step.
13th: the 13th note of a major scale (same as the 6th, except an octave higher).

So you can add a 6th to a major or minor triad to create a brighter sound. You can add a major 7th to a major or minor or diminished triad to create another kind of sound. You can add a 7th (dominant 7th) to a major, minor, diminished, or augmented chord to create another kind of sound. Or you can add a 7th along with a 6th; or a 9th along with a major 7th; or a 9th along with a 7th; or an 11th along with a 9th and a 7th; or a 13th along with an 11th and a 9th and a 7th.

And on and on. We could go on combining color tones until the cows come home, but the best way for you to learn what's possible is to just dig in and experiment. You'll find many, many exciting combinations you can use in various musical situations that will brighten your song and add a rainbow of colors to your creative improvisations.

Inversions: How To Stand a Chord On Its' Head

Inversions: How To Stand a Chord On Its' Head

Many people get all confused when chords are turned upside down. They recognize them when they are in root position, but when you stand them on their head...well, it gets kind of fuzzy for folks.

That's understandable. We grow up playing chords in root position, which means that the name of the chord is on the bottom, with the other two notes an interval of a 3rd above each other. (E is a 3rd above C, and G is a 3rd above E). For example, when we play the C chord in root position, C is the lowest note in the chord, so it seems obvious that it is the C chord.

But when we see the C chord with E on the bottom, or G on the bottom, it's not so obvious, partly because the chord is no longer a stack of 3rds.

Chords upside down are called "inversions".

Here's the deal:

Every 3 note chord (called a "triad" -- trio -- tricycle -- meaning "3") can be played in 3 different positions -- inversions:

Root position = The name of the chord is the bottom note
1st inversion = The name of the chord is the top note
2nd inversion = The name of the chord is the middle note

So when C is the lowest note of the C chord, it is called "root position". When C is the top note of the C chord, it is called "1st inversion". And when C is the middle note of the C chord, it is called "2nd inversion".

So a root position triad (a triad is a 3-note chord) is a stack of 3rds; actually, a minor 3rd on top of a major 3rd. A first inversion triad is a stack with an interval of a 3rd on the bottom and a 4th on top. A second inversion triad is a stack with an interval of a 4th on the bottom and a 3rd on top.

So what?

Here's what: Each inversion has it's own sound, so you can get a variety of sounds by using one inversion and then another. Each inversion also has its own feel, so some pianists find it easier to use a particular inversion than others, particularly to move smoothly from chord to chord.
So what happens when there are more than 3 notes in a chord, as in a 6th chord or a 7th chord?
Same deal -- it's just that now there are 4 positions of the chord instead of 3 as in a triad; root position, 1st inversion, 2nd inversion, and 3rd inversion. That gives the pianist lots of choices for voicing and fingering.

There's no law, either, that a pianist has to use all the notes of a given chord. If I want a more open sound, I might leave out the 5th of a 4-note chord, and just use the root, 3rd, and whatever the other note is -- 6th, 7th, major 7th, 9th, or whatever.

For example, I might voice a C7 chord with E on the bottom, skip the G, then include the Bb and C. Or I might play it as an arpeggio (broken chord) by playing a low root an octave lower, then play the 5th, then the 3rd an octave higher, and then come back to the Bb.

The choices are almost infinite, and the more complex the chord, the more exciting voicing choices there are.

So don't settle for just one position of a chord -- stand it on it's head and experiment with all the luscious choices for voicing it to create a sound all your own.

Sprinkle Some Pepper On Your Musical Meal Through The Use of Augmented Chords

Sprinkle Some Pepper On Your Musical Meal Through The Use of Augmented Chords

Augmented chords are to a piece of music like pepper is to a meal; you would never sit down to a meal of pepper alone, but you might sprinkle a little on your food to liven up the taste a bit.
Augmented triads (triads are 3-note chords) are one of the 4 basic chord types, yet they are used very little compared to major and minor chords.

There are four basic kinds of triads in music:

Major triads: composed of the root, major 3rd, and perfect 5th of a major scale.
Minor triads: composed of the root, minor 3rd, and perfect 5th of a major scale.
Diminished triads: composed of the root, minor 3rd, and diminished 5th of a major scale.
Augmented triads: composed of the root, major 3rd, and augmented 5th of a major scale.

As an example, the C major scale is:
C, D, E, F, G, A, B, C

So a C major triad would be:
C, E, G
A minor triad would be:
C, Eb, G
A diminished triad would be:
C, Eb, Gb
An augmented triad would be:
C, E, G#

Most of the songs we know or hear on the radio or TV (or on our IPOD's or other MP3 player) are written in a major key. That means that most of the chords in those songs are major chords -- only 20% or so are minor chords.

The other 10% of songs and musical compositions are written in a minor key, which means that there will be several minor chords within the context of the piece.

So if nearly 100% of all songs contain major and minor chords, what place is there for diminished and augmented triads?

They are the salt and pepper of a musical meal.

In other words, major chords are like the main dish -- the steak, if you will, of a song. Minor chords are like a side dish of corn or broccoli (yuk!) or whatever. You would never sit down to a meal of just pepper or just salt, would you? Same way here; you use diminished and augmented triads to add spice to your meat and potatoes. We covered diminished triads in an earlier article, so this time we will focus on augmented triads.

Here are the 12 augmented triads:

C aug: C, E, G#
F aug: F, A, C#
G aug: G, B, D#
D aug: D, F#, A#
E aug: E, G#, B# (enharmonic with C)
A aug: A, C#, E# (enharmonic with F)
Db aug: Db, F, A
Eb aug: Eb, G, B
Ab aug: Ab, C, E
Gb aug: Gb, Bb, D
Bb aug: Bb, D, F#
B aug: B, D#, Fx (F double-sharp, which is enharmonic with G)

So like diminished chords, augmented chords are used to add spice to your musical meal. You don't linger on them, but use them as transition chords between a major and another major chord, or between a major and a minor chord, or sometimes even between two minor chords.
As an example, let's say you are playing "Battle Hymn of the Republic" in the key of C and your first chord is C major on the entire first phrase "Mine eyes have seen the glory of the coming of the Lord" As you transition to the F chord on the word "trampling", you can insert a C augmented triad on the words "He is". It only lasts one beat, but it adds interest to the song by leading smoothly from the C chord to the F chord.

You could also use a C augmented chord in the chorus as you move from the 1st phrase "Glory, glory, hallelujah!" to the second "Glory, glory, hallelujah!" You are moving from a C chord to an F chord, so insert a C+ chord (the symbol for an augmented triad is a + sign) right before you play the F chord.

As you play various songs, look for opportunities to use augmented triads as transition chords. And just like pepper is to a meal of food, so augmented triads are to a musical meal.

Learn Music Fast -- Online!

Learn music fast online

With the advent of the internet there is no longer any excuse for not learning music if a person wants to learn. Learning music online has revolutionized learning, since it is the first time in history that anyone with a computer can virtually find out anything they want to know about music -- and find out quick!

There are sites galore teaching everything about music from chords to trombone lessons to drum lessons to music theory lessons to guitar lessons to piano lessons, and a whole lot more. Many are free while others charge a very reasonable tuition. But think what a bargain that is; no travel, no traffic jams; no rescheduling lessons; no missed lessons; and because the lessons are online (or in some cases on CD's and DVD's) they can be replayed over and over until the lesson is thoroughly learned, which is not the case in a personal lesson or a college classroom. You have one chance to understand, and if you don't, you're immediately behind the curve and have to do extra studies to catch up. Not so with online music lessons.

Back just 15 years ago if an individual wanted to learn music, about the only places he or she could do so would be from a private teacher, a music school of some sort -- private or public or correspondence, or self-taught from a music book. All of which is fine, but slow if an individual is really chomping at the bit to learn, and learn fast.

But today there are literally hundreds of sites on the internet from which any ambitious person can access and learn virtually anything they want about music. There are sites dealing with music instruction for beginners as well as college-level sites that deal with figured bass and advanced music theory and composition issues, as well as improvisation and arranging music.

For example, there are piano lesson sites that teach how to improvise -- all styles of improvisation including jazz, rock, gospel, new age music and more. There are piano instruction sites that shows you how to play piano sheet music as a map, instead of having to sight read the printed music as it is written. By learning how to do this, you can create your own free piano sheet music by creating a song and then notating it in a music software program such as Finale using piano tabs, piano chords, and chord symbols. A person can learn to play piano notes by the fist-full by learning piano chording music styles.

Learning to play the piano, learning to read piano music, learning piano songs from classical music to popular music is one of the most fun things a person can do. There are piano lessons online using major chords, minor chords, 7th chords, and all kinds of chord progressions. Learning to play the piano music of your dreams using piano chords & piano chording techniques is now within the reach of anyone with an internet connection! And don't forget harmony and music theory -- including scales and fingering of scale and chord passages in musical scores and sheet music -- it's all available online. Music history and music appreciation is important too -- guys like Bach & Mozart & Beethoven & Chopin knew what they were doing -- and we can learn much from them and stand on their shoulders simply by accessing the biggest library in the history of mankind -- the cyber library of the internet.

Here are just a few of the sites online where you can learn music:

http://www.workshoplive.com/ Guitar lessons online using video. Song writing instruction.

http://www.berkleemusic.com/ The Berklee School of Music in Boston has long been one of the two or three top schools in the world for aspiring jazz musicians. Now it has an online division, so you don't have to pack your bags for Boston -- you can learn music right at home.

http://mto.societymusictheory.org/ Music theory and criticism for advanced musicians, teachers, composers, and scholars.

http://www.musictheory.net/ Includes introductory and intermediate music theory lessons, ear training.

http://www.murraystate.edu/qacd/cfac/music/MUS109e/intro/chapter_index.htm An interactive internet course for learning music fundamentals. Designed to be a high school AP course or freshman college level remedial theory course.

http://www.teoria.com/tutorials/index.htm Tutorials on reading music, scales, intervals, chords.

http://www.playpiano.com/101-tips/FreeLessons.htm 101-part online newsletter teaching piano chords & chord progressions.

This list just scratches the surface; if you type "music lessons online" into the Google search box, you will come up with something like eight million results! "Piano lessons" will call up about a million and a half, while "guitar lessons online" will bring up over two million search results.

With this abundance of material online, there is no excuse for anyone who really wants to learn music to not avail themselves of the opportunity, especially when they realize that this is the first time in the history of the world that this riches of knowledge has been available with just the click of a mouse.
