Using empty cells to control chord duration
I'm not able to fully understand the logic of how empty cells end up specifying chord durations, especially in odd time signatures. For example, in Take Five (5/4) section A, both Ebm and Bbm7 are followed by a single blank cell, but somehow the player translates this to Ebm playing for 3 beats and Bbm7 for 2. How does that work? What if I wanted to play Ebm for 2 beats and Bbm7 for 3?
An authoritative and comprehensive documentation of the beat scheduling logic would be great!
