scales ??

Thanks for your help. I wasn't lost about using scales for solos, just the whole playing them over chords thing. Even more lost if the guitarist is the only guitarist in the band.

I actually made a solo using a scale, to try and understand it more. Used the Ab Major scale and came up with this:

D|-------------------------------------|
A|-------------------------------17-15-|
F|-------14-15-17-------14-15-17-------|
C|-15-17----------15-17----------------|
G|-------------------------------------|
C|-------------------------------------|
