Band Improvisation Lesson

I try to get right to three things:

1. Chords, scales, theory.
2. Improvisations.
3. Arranging on the fly.

So I taught students three riffs based on blues scale.  We also practiced the major scale do-sol-do.  I asked them to decide what riff they would play and when they would switch.

There are 13 musicians in the room.  Some are 2nd-3rd year players, 5 of the 13 are on their 3rd lesson on their instrument.
