Okay, campers, listen up: it’s time to talk about…
SEQUENCE.
Yes, sequence. A fundamental building block of music, and a very handy device in the improviser’s toolkit.
What is sequence? There’s nothing mysterious about it. Sequence is simply the repetition of a melodic idea beginning with different tones. Sequence can be diatonic within a key, and many scale exercises consist of scale material organized sequentially. Sequence can also be an exact, interval-for-interval repetition of a motif (or lick), which often–indeed, almost inevitably–will take you out of key.
The beauty of sequence lies in the coherency it brings to a solo. Sequence is a means of organizing melodic material in a way that the listener can immediately relate to. In the midst of a free-form flow of melody, sequence provides a sense of logic, a momentary theme for the ear to latch onto and follow through one or more permutations.
In its simple, diatonic form, sequence creates interest as you navigate your way through a single scale, chord, or ii-V7-I cadence. But sequence can also be used to take you out of key The strength of repetition has a way of making “wrong” notes sound right–a quality that becomes increasingly important when you’re playing tunes with little in the way of harmonic interest. When you’re in the midst of a two-chord jam, diatonic scales get boring pretty quickly. You’ve got to create energy. How? By using chromaticism–tones outside the key center that add color. Sequence is a great way to do so in an organized fashion.
Now, one picture is worth a thousand words, right? “Don’t tell me, show me,” is what you’re thinking. Relax. I’m not going to leave you hanging without a few examples. I’ll provide some material you can practice in an upcoming post. Right now, I just want to introduce the concept of sequence and whet your eagerness to get a few exercises under your fingers.
“But I want to start noooowwww!!!”
Patience, Grasshopper. It’s Saturday afternoon, it’s spring, and I want to get out and enjoy the day. Stay tuned, though. I’ll be back with a few goodies. Promise.
