Is it really common to perform easy jazz standards with 4 modulations? My band hosted an open mike a few days ago on New Years Eve and I doubled with elec. and upright bass. After our opening set, a drummer and guitar guy ask me to play 3 with them for the open mike. OK, first off, a bit of background. I've only been playing upright 12 months with jazz instruction. And I don't play a lot of open mikes but I have more time to get out now. What are we playing? "Blah,blah and Mack the Knife. We like to hit hard and fast. We like to make it interesting" guitar guy says. "Sure, no problem. Vi-I-ii-V right?" I reply. "I've never played it but I'll pick it up." The first 2 songs are all sounding good. Then we started Mack the Knife. Guitar guy is good but he's playing Green-style four changes to the measure and I'm having a h-ll of a time figuring out the song. I'm looking at the drummer who advised me to just walk the chords. Sure, why not : ) THEN, the modulations start. Guitar guy did (I confirmed later) 4 key modulations in that one arrangement. I just couldn't keep up and it wound up sounding like a train wreck. Luckily we ended with an easy Willie Dixon number and kept the packed bar happy. Now, I've got long-time supportive friends at this place and it IS only an open mike. But I practice every day, work on my theory, and like to hold my end up musically. So I like to be prepared for the call, so to speak. Anyone else here do this or play with people who insist on 4 modulations with on-the-fly performances?
