Example of what I mean. Chord progression as I said before would be in C major. While the scale you might use for the solo is the C minor pentatonic. This is common practice in rock and blues. The third of C minor (Eb) is the blues major tone (b3) of the C major blues scale.

Lots of great stuff, noticingthemistake. However, I reacted on this little paragraph you wrote.

The chord progression is in C major. Then you suggested using C minor pentatonic for soloing? Wouldn't that sound rather... unpleasing? I mean, the C minor pentatonic has got notes that don't appear in the C major scale. That's why I thought it would sound strange.

How about using the A minor pentatonic instead (as all of it's notes are present in the C major scale), over a progression in the key of C major. Let's say the tonic chord of the progression is A minor. Then use A minor pentatonic for soloing. Or, why not use the A minor scale (Aeolian/6th mode), as long as the chord progression starts and ends on the A minor chord.

What do you think?
