"C" is pretty darn easy so we'll start with that
If you build triads of the chord (every other note, for 3 notes starting on the root) you here different sounds:
C E G (C major)
D F A (D minor)
E G B (E minor)
F A C (F major)
G B D (G major)
A C E (A minor)
B D F [B diminished (triad form)]
Now if you have a chord progression using only these chords, then you can use the C diatonic scale. Pretty nifty huh?
But don't let that limit you... just cuz I say you "can" use those notes doesn't mean they all sound good, they are a suggestion... Many other notes (outside the scale)sound good as well.... let your ears be your guide... and fool around with arpeggios too.
There are only two important things in life - There's music and theres girls, not necessarily in that order....
