The problem ( as I see it) is it is not just the need for more chords per bar, but also the resolution of the bar for where you can place the chords. With quarter note reolution only 4 chords are posssible, with eight note, 8 chords... and so on. Now BIAB can push a chord to place in at an 8th note resolution but then it can't place a second chord an the next eighth note... So while John has a good point and I agree (this is unusual ), rarely do I like to play four chords, or more) per bar except slow tempo stuff however, However, where these chords are placed in the bar can be critical.. Does that make sense?
