I'm familiar with the chord-scale system (https://en.wikipedia.org/wiki/Chord-scale_system) that dictate what scales go with what chord, and vice versa.
But I can't find much info about how jazz musicians choose WHAT chords and scales to play given this information.
For example, if a jazz pianist is putting together a tune or improvising something in C lydian over a C7 major chord, how'd they decide what chord or scale to move onto next? Stay in C lydian, but change the chord to G7? Keep playing over C7, but change the scale to harmonic major? Or do something crazy like change the chord to Caug, and play the whole tone scale?
So, are there any rules or guidelines that are used in jazz to decide:
1a) If one chord will sound 'good' (won't clam) after another chord
1b) Likewise, if one scale/mode won't clam after another scale/mode
2) When are good times in a song to change between chords and scales
