You don't see them much anymore except in music theory books. But Roman Numerals used to be used extensively to show what chord is being used in a piece of music, and what inversion of the chord is to be used. They were musical symbols, much like chord symbols are today.
Here is a chart showing the relationship of Roman numerals used in music to classical definitions:
I Tonic
V Dominant
IV Sub-Dominant
ii Super-Tonic
iii Mediant
vi Sub-Mediant
vii Sub-Tonic
And by the way, that is the order of likelihood as well -- the Tonic (I -- the home base of any key) is the most used and most likely chord in any key. The Dominant (V) is the next most used and most likely chord, followed by the Sub-Dominant. Those are the "Big 3" -- also known a the "primary chords" in any key.
After the primary chords, the next most used chord is the ii chord (notice the lower case Roman numerals -- that indicates that the chord in it's natural, organic state, is minor. Next comes the iii, followed by the vi, with the vii bringing up the rear.
Inversions are shown by an Arabic number following the Roman Numeral, such as I 6/4 , or V 7, or IV 6.
Roman Numerals without an Arabic number following it would assumed to be root position chords. Those with an Arabic "6/4" would mean 2nd inversion of the chord, while an Arabic "6" following the Roman Numeral would indicate 1st inversion. A "7" after a Roman Numeral would mean to add a 7th to a chord.

How Can I Train My Ear To Hear Intervals -- 2nds, 3rds, 6ths, etc?
If you learn to "hear" an interval in your mind, and know what it is, then it is easy to reproduce that interval on the keyboard -- and that, of course, is what "playing by ear" is all about -- mental hearing and then reproducing what you hear on the keyboard. (This course is also excellent for singers and instrumentalists!)

Intervals: The Distance Between Any Two Notes
The interval's quality is a bit more complicated. Interval quality describes the specific type of the intervals in addition to the number; intervals can be perfect, major, minor, augmented, or diminished. But not every interval can be of every quality. While all intervals can be augmented or diminished (by adding or subtracting a half step, respectively), only unisons, fourths, fifths and octaves can be perfect; a perfect fourth is five half steps, a perfect fifth is seven, and a perfect unison is zero (since a unison represents the same two notes). Similarly, only second, third, sixth, and seventh intervals can be major or minor; like augmenting or diminishing, this is achieved by adding or subtracting a half step from the intervals.
But be careful. Since major and minor intervals are created by altering the intervals by a half step, augmenting and diminishing works a little differently here. Instead of simply adding or subtracting a half step, augmented intervals (in this case) are a half step more than the interval's major, and diminished intervals are a half step less than the interval's minor. Let's consider third intervals, for example. Major third intervals are four half steps and minor third intervals are three; in a fourth interval, that half step down that creates the minor would create the diminished. But for these intervals we have to go a half step below that, making a diminished third two half steps (which actually creates major second intervals, but that's a story for another time).

What's The Difference Between An Acoustic Piano & A Digital Piano?
What makes a digital piano sometimes more desirable than an acoustic piano (when it comes to popular music, at least) is the sheer number of features that enhance the experience of playing. For instance, one push of a button can transpose the entire keyboard on a digital piano to any key desired and middle C can be placed anywhere on the keyboard. Additionally, the keys on a digital piano can be adjusted to have as much or as little touch sensitivity as the pianist desires. A digital piano can also control a variety of audio functions, including sustain and delay, and be used as more of a synthesizer than a piano. And what's more, a digital piano can be programmed to play more than one sound when kitting a key or the keyboard can be split to put the bottom half at one sound and the top half at another. It's an extremely versatile instrument; a digital piano can be made by its user to sound exactly like a real piano or anything but.

Play That Honky-Tonk Piano!
Out of honky tonk - or at least contemporary with it - came boogie woogie, blues, and jazz. Perhaps the closest thing to that style of playing today would be Jerry Lee Lewis.
Honky-tonk piano is a very rhythmic, very rollicking style of piano playing most often associated with ragtime. The term itself comes from a name given to certain bars in the early 20th century; these were rough bars that often encouraged rowdy behavior and brought in self-made piano players to entertain the roughshod crowd. When honky-tonk piano first emerged, it seemed to be a musical representation of that type of behavior; honky-tonk piano was rowdy and rough, catering to working-class audiences who just wanted to dance and have a good time.
The honky-tonk piano style itself is extremely distinctive, enough so that a particular sound associated with it is included on modern digital keyboards. It's a slightly out-of-tune, twangy sound that reflects an old piano being played in an old bar. It's similar to ragtime; but unlike ragtime, honky-tonk piano is less concerned with overt melody and more with the percussive elements of the player. It was extremely rhythmic, extremely danceable and extremely popular among ragtime fans. And what's more, honky-tonk piano eventually went on to inspire a whole host of piano styles, including some branches of jazz and boogie-woogie; in some ways, the original honky-tonk piano was a precursor to the familiar walking bass found in a variety of musical styles.
Honky-tonk piano has since morphed into a style different from that of ragtime, a style sometimes associated with backwoods country music. It could have something to do with the honky-tonk piano's specific sound; the out-of-tune honky-tonk piano tone at times mimics the quality of instruments like banjos and fiddles, creating a great complement to the fast, vivacious music found on the front porches of southern homes. And honky-tonk piano even moved forward to influence many branches of modern country music, especially alternative country that relies heavily on rhythmic elements as opposed to melodic.

What are those little short lines above and below the staff?
On the other hand, however, multiple leger lines can be too difficult to read. Notes located on three or four leger lines are usually engrained into a musician's sight-reading knowledge, but anything more than that can trip up the efficiency of a reading. It's difficult to smoothly read a piece of music while trying to count leger lines and figure out a very high or very low note. In these situations, a clef change is absolutely necessary. Still, it's the composer's choice whether or not to use leger lines here. If he or she is confident that those reading the music will be able to decipher it, leger lines may be used uniformly without a clef change, even if a clef change would be theoretically correct.

What does "metre" mean in terms of musical rhythm?
The metre of a song is indicated by that song's time signature; metre is the physical form of that notation. Just as a note is the written form of a pitch, time signature is the written form of metre. It gives us the specifics of a metre, but doesn't replace it. Understanding how time signatures function in the way that they do is the very basis of metre.
A song's metre is understood by two elements: how many beats are in one measure and what type of note constitutes one beat. A 4/4 metre, for instance, has four beats per each measure with the quarter note making up one beat. A 3/4 metre has three beats per measure with the quarter note making up the beat. A 6/8 metre isn't read like this, however; it has two beats per measure with a dotted quarter note making up the beat. This type of metre, the kind shown by a time signature with a top number of six or higher that is divisible by three, are compound and found by dividing the top number and multiplying the bottom number by three.
Metre comes in tons of forms, straightforward or syncopated. A 4/4 metre is the most common, used almost without exception in rock and pop songs because of its straightforward beat that makes writing to it (and following it) very easy. 3/4 metre is the second most common, creating a swingy, syncopated beat; this is also found in rock and pop songs, most typically in slower ballads. 6/8 metre is home to the waltz, 12/8 metre is used by blues musicians, and 2/2 metre (also called cut time) is what marches are made of. But other sorts of metre, like 6/4 or 5/8 or even 13/4, are often used to innovative effect, creating an effect that makes the rhythm hard to pin down. Though this type of metre, known as irregular, are largely known for being hard to follow, some musicians have made it clear that a song does not have to be in 4/4 to be catchy. Consider Dave Brubeck's "Take Five." Sure, it isn't 4/4, it has an offbeat nature, but it certainly isn't hard to follow, and those 5 beats per measure kind of keep us constantly surprised. The metre provides the heartbeat, and the rest of the song follows it; if that heartbeat keeps going strong, the listener is bound to follow it as well.

Chords Are LIke Us -- They Take Familiar Paths Too, Called "Chord Progressions"
Is that the only way I could get there? Of course not. There are probably a dozen or more ways I could go, but like most people, I am a creature of habit, and so day after day, year after year, I drive the very same way.
Chords are like that too. There are an infinite number of ways chords could progress, but if you toss all the songs ever written into a giant computer and have it spit out the most common chord progressions, you'll find that the top 5 or 6 progressions are used perhaps 80 or 85% of the time.
Why is that? Because songs are composed or made up on the spot by people -- not some music machine. And people take familiar paths, just like I drive the same way to town day after day.
Chord progressions are based on a series of chord changes, and these changes form the basis for the melody to be formed. Chord progressions are the harmonic backbone of a song, and they often dictate the song's tone and mood. Modern music tends to frequently base chord progressions out of the first, fourth, and fifth degrees of the scale; in C major, this would be C, F, and G. Of course, these chord progressions can be varied in a number of ways (chord substitution allows heavily for that), but these basic chord progressions tend to be the framework for a decent portion of modern music -- especially rock and pop.
Some of the most used chord progressions are: I, V7, I; I, IV, V7, I; I, vi, ii, V7. These progressions happen over and over and over and over again in literally thousands of song. For further information please check out Familiar Chord Progressions.

For a good overall musical education, join a choir
Though some types of choir, such as the community choir, don't require much out of an audition (if they require an audition at all), there are certain traits a vocalist must possess in order to be able to handle the duties of choir membership. First and foremost, the choir member must be able to sing in tune; it seems common knowledge, but many would-be choir members are impervious to this ability. But singing in tune isn't enough -- choir members must also be able to blend their voice within the presence of other voices, to control vibrato and volume; the point to a choir, after all, is to hear an amalgamation of voices not one in particular. It is also vitally important that a choir member be able to read sheet music. An inability to read music will inevitably lead to the choir member never being able to learn his or her parts. Sight-reading, or the ability to read a piece of music without ever having seen it, is especially preferable for choir members, as a conductor will frequently ask the choir to sing through an entire piece immediately in order to get a sense of the music. Lastly, a choir member must have an independent ear; that is, they must be able to sing their part even while hearing a different part coming from the alto or tenor section. If a choir member has this problem and it's very slight, the conductor will usually place them in a position far from any imposing alternative parts, but a consistent inability to hear one's own voice will ultimately lead to a choir member having a difficult time with the entire performance.
