A Thelonius Monk rhythm changes bebop head for unison playing. Playing a less known head in unison at a jam online can be a bit tricky. Some people are good readers, others are not. Each one has a more or less personal idea about phrasing.
Another question is how the sound of the different instruments might blend. In this recording there is a trumpet, a flute, a trombone and a tenor sax plus my violin. They are not exactly together but close enough.
Rhythmically this head is a bit odd, that is why I recorded it to serve as an example of how we might do it. It is rather minimalistic with little rhythmic traps where counting may be good thing to do.
