1. Any note to the next higher note with the same name above it is called an octave.
2. There are 12 notes to an octave.
The pitch of notes are intervals of frequency.
Frequency is measured in hertz (hz).
3. The mathematical relationship between octaves is 2:1.
For example: If a 'C' is oscillating at 100 hz, the "C" above that is oscillating at 200 hz, and
the "C" above that on is oscillating at 400 hz.
3. A scale is a series of notes in an octave. Our major and minor scales have 7 notes. For example:

the notes of a 'C' major scale are C,C,E,F,G,A,B and then you repeat the C one octave higher
than the first starting C.
