Play an A minor pentatonic scale... right... now, a C major pentatonic scale has the same notes, so you could play a C Major pentatonic scale over a backing track in the Key of A minor, and it would work....
Chromaticism - you can play pretty much any note.... it's about how you resolve a phrase. Try it - put on an A minor backing track, and play any 4 notes within 1 octave, and finish on a chord tone (A, C# or E for this example)...
There are players who claim to know nothing about scales etc, they just play what works - Ritchie Kotzen is the best example I can think of. Playing his stuff makes no technical sense sometimes, but it sounds cool... :cool:
