]]> ]]> A diagram of the cycle of 4ths/circle of 5ths,
lists of key signatures written on the treble-clef,
and formulas of intervals that common scales are built with.

Starting at the top of the cycle of 4ths/circle of 5ths:
Keys written with sharps progress clockwise,
keys written with flats progress counter-clockwise.

The scale formulas are all listed relative to C as their scale root.
Brackets above each scale identify the intervals between scale tones.
(H = half step) (W = whole step) (-3 = minor third)
