See the lick written out at: http://jazztrumpetlicks.com...... This is an a pretty easy ii V7 I Jazz lick that starts on the 5th of the dominant scale or the one of the ii chord, then goes up the dominant scale until you land on the 3rd of the I chord. You can land on the 3rd on the one or the V7 chord and it will still sound good. In this video I landed on the 3rd on the V7 chord. I hope you enjoy the sound sample over the Bb blues on trumpet.
