If you were in a jam where everyone(guitar, Bb trumpet, bassist, drummer, and you on keys) was in G minor, and the tempo was 115 bpm, and all the jam was was just a repeating two bar sequence of one bar of Gmin6 then one bar of Gmin, how would you solo, without a prior melody to framework how you should play? or would you typically avoid this kind of situation?
this should be a very open jam. a lot of room, everyone should listen to each other. g dorian should technically be your home base but you're free to go to mars. especially if you are the only chordal instrument and it's your solo, you can go anywhere really. the bass player should be listening and supporting where you're going. technically your home base is g minor / g dorian but there is plenty of room to go totally wild, because there is nothing really happening in the chords
