@.@

It can now be deduced that the major scale with four flats is Ab major (Bb, Eb, Ab, Db), that the one with five flats is Db major (Bb, Eb, Ab, Db, Gb,) and that the one with six flats is Gb major (Bb, Eb, Ab, Db, Gb, Cb).
Gb, however, is the enharmonic if F#, and F# (as already seen) is the key note of the scale with six sharps. We seem to have come to a halt: we now have a major key signature for each note on the keyboard, indeed two for one of them (F#/Gb). But if we were to carry on further, we would continue to get enharmonic alternatives. For exaple, if we extend the sequence of keys with sharp key signatures, (G, D, A etc.) we get .....

is it me, or is music theory just getting more chimology with every page i turn? woah @.@ i'm going bonkers lol.
