Learn to scout a song before you play it

It's always a good idea to scout a song before you play the song. In other words, take a look at the key signature and the time signature and see if there's any repeats in the song. In the key signature note which sharps or flats or being used. If there is one flat in the key signature then the song is in the key of F. if there are two flats in the key signature then the songs in the key of B. flat. If there are three flats in the key signature then the song is in the key of E. flat. If there are four flats in the key signature then the song is in the key of a flat. If there are five flats in the key signature, the key is D. flat. If there is six flats in the key signature, the song is in the key of G. flat.
 If there is one sharp in the key signature the song is in the key of G. If they are to sharps in the key signature the songs in the key of D. If there are three sharps in the key signature than the song is in the key of A.If there are four sharps in the key signature the song is in the key of E.  If there are five sharps in the key signature the song is in the key of B. if their sex sharps in the key signature of the song is in the key of F. sharp.
As far as time signatures are concerned, be sure to notice the top number of the time signature. That tells you how many counts are in each measure. The bottom number of the time signature tells you what kind of note gets one count.

Changing Keys

Modulation is a fancy word for key change -- switching from one key to another in a single piece of music. It is a common practice in composition (both classical and rock or pop) and can be used to a variety of effects. Modulation can be subtle and smooth or abrupt and startling. It can cast an eerie glow on a piece of music or completely change the mood and direction. The effect achieved, however subtle or abrupt, is largely dependent on the type of modulation used.


The most common type of modulation is called pivot chord modulation. In this type of modulation, the key changes based on a chord shared by both keys; the destination chord often has the same root note or quality as the original chord. This allows for a smooth, almost foreshadowed modulation. A good example of this is found in the last chorus of rock songs; this type of modulation is used there to an almost triumphant effect.

Another common type of modulation is pivot tone modulation. Similar to pivot chord, pivot tone modulation uses a common pitch to move from key to key. This type of modulation is also subtle, depending on the piece of music in which it is used. It can, however, be used to a startling effect if the two keys have few notes in common. In songs using pivot tone modulation, the common pitch is often sustained or repeated and used a bridge between the two keys.

The most abrupt kind of modulation is direct modulation. The name is exactly what is says it is: a direct modulation using no common note or chord to bridge the two keys. When used correctly, direct modulation is shocking and can easily change the song's mood. This type of modulation switches keys either at a phrase's end (phrase modulation) or at a point in the middle of the song (static modulation).

What do those numbers at the start of a piece of music mean?

Numbers such as 4/4, 3/4, 2/4, 6/8 and so on which appear at the beginning of a line of sheet music are called "time signatures". The top number tells how many beats are in each measure, while the bottom number tells what kind of note gets one beat (one count).

For example, in 3/4 time there are 3 beats in each measure, and a quarter note gets one count. If the time signature was 3/2, there would still be 3 beats in each measure, but a half note would get one count.

In 6/8 time there are 6 counts per measure and an 8th notes gets one count.

There can be "odd numbers" such as 3, 5, 7, 9 on top, but never on the bottom, because the bottom number describes the kind of note that gets one count, and there are no "3rd notes", "5th notes", and so on -- just half, quarter, eighth notes, etc.

How the piano got its name

Prior to the invention of the piano there was an instrument called a harpsichord which was played by playing a keyboard but the result was plucking of the strings similar to a guitar. And prior to the harpsichord there was an instrument call the psaltry which was played by actually plucking the strings. Later the psaltry had a keyboard, and that led to the harpsichord.
When the piano was invented somewhere around 1700, it was novel in that instead of the strings being plucked they were struck by a hammer which was inside the piano.As a result music could be played both soft and loud which was not true with the harpsichord or the sultry. So it was named the "pianoforte" which in Italian means the "soft loud instrument." It was refered to this way for many years until finally the "forte" part of the name was left off and was just refered to as the "piano." Kind of strange in a way, since in Italian the word piano means soft. So to be literal, you are playing the "soft." when you play the piano, even though you play it using a variety of dynamics.

What Does "SATB" Mean?

On certain types of music you will see the notation "SATB", and unless you have been in a choir somewhere along the line, you might not understand what it means.
It means "soprano, alto, tenor, bass", and so music that is written in this way was obviously written for voices, not for the piano or some other instrument. But most every hymn book is written SATB, so what is a piano player to do?

If he or she plays it as it is written, it sounds vacant, because 4 piano notes cannot adequately mimic 4 human voices. So a piano player needs to be able to "see through" the 4 parts and come up with the chord those 4 notes are spelling out. Once the chord is known, then the pianist can fill in with a much larger sound to accompany the singers, or if playing solo, improvise based on the chord structure of the song.
