I have recently been studying the nature of the fugue.
Here's my take on the art:
Fugue in C major - (v.1.2, at least an improvement)
It starts of i C and then modulates through all the major scales of the cycle of fifths, moving clockwise.
thus, C, G, D, A, E, B, F#, Db, Ab, Es, Bb, F, then at last returning to C.
