Half-Step Slips By Michael Hoffman
Here's a great way to spice up your solos. The concept is simple: While you're improvising with a scale, momentarily move your line a half-step up or down to create tension. Slipping back to the original scale releases the tension. Moving up or down -- going out -- is easy. Getting back in smoothly takes a little practice.
Outside in. This example illustrates the process. Begin by playing A Dorian (A, B, C, D, E, F, G) over Am7 as notated. Notice how the line shifts to B Dorian (B, C, D, E, F, G, A) on the and of beat four. This tension-producing "half-step higher" state lasts through bar 2, beat three. The F passing tone (labeled PT) adds even more drama within B Dorian. After returning to A Dorian, the line drops to A Dorian (A, B, C, D, E, F, G) for four beats and then rejoins A Dorian for one final note.
Other flavors. Once you've learned this phrase, try giving major and dominant scales the half-step slip. For best results, establish the sound of the inside scale before you move outside -- and be sure to wind up back inside!
