Tenth
The
interval of a compound third, in other words, an octave plus a third.

Third
The interval between two notes which are three notes apart on the
scale. The notes could either be one after the other in melody, such as in the start of "A Day In The Life," or both together in harmony, such as in the first note of  "Bye Bye Love".

Time Signature
A fractional number placed at the beginning of a composition to indicate the number of
beats in each bar and the value of each beat. Examples include 2/4, 4/4, and 6/8. The first of the two numbers indicates the number of beats in a bar, and the second number indicates the type of note that equals one beat. 2/4 time signifies two beats in every measure, with each beat having the time value of a "crochet".

Tonic
The "home" note, or
chord, of a key or scale - the "mice" in "Three Blind Mice" is the tonic note, and the tonic chord is where the vast majority of songs end unless they're fading out.


Trilling
The repeated playing of two
notes in rapid succession. This technique can be used as a substitute for sustaining a note in those instruments, such as the piano, which cannot naturally sustain.

Twelve bar blues
A form of song construction that relies upon a fixed sequence of
chords occurring over twelve bars. Its form comes from a three-line verse or chorus. Each line consists of four bars (3 x 4 bars equals 12). Many of the rock 'n' roll songs of the 1950s followed the twelve bar blues chord progression.
