I have been asked to sit in with a local high schools jazz band for a few Miles Davis tunes in their spring concert in a few weeks. Three are pretty up-tempo (Milestones, Seven Steps to Heaven, and So What) and the fourth (Blue in Green) is anything but. When I began shedding I expected the first three to give me the most trouble but actually I have struggled more with Blue in Green. They are playing it at about 55 beats. As a bluegrasser, I am having trouble adapting to this speed. Tips? Ideas? Advice? Prayers?
