Alright....now I asked a question about chords in another post, now this question is about using scales when filling in. Now let's say you are in the key of again a simple Cmaj.....let's say the keyboardist is holding or just played let's say a Emin chord and you to put a fill in bringing you in to your next bass note (after you applied your bass note for the chord) if using a scale as a fill would you use the scale corresponding to the key the song is in or the note or root of the chord that is being played, or the scale of the note that you are approaching??? Thanks a lot guys, you have been excellent help so far!!!!
