All About Guide Tones

Guide tones, also known as target notes, are commonly used in jazz improvisation and usually refer to only the 3rd and 7th of a chord. But, for our purposes, we’re going to apply a more generous definition where all notes of a chord can be used. There are two benefits to using guide tones: They create a predetermined melodic structure that serves as a framework for your solo, and they provide an inner melody to your lines that carry the sound of the chord changes.

The first two examples show a couple of possibilities when building a guide tone melody over a ii-V-I chord progression in the key of C major. The only requirement is that the guide tones should be played on the strong beats of the measure (beats 1 and 3). Next, spell each chord to see what notes you have to work with. For our progression, our choices will come from Dm7 (D-F-A-C), G7 (G-B-D-F), and Cmaj7 (C-E-G-B). Since these examples have one chord per measure, I have chosen to use only one guide tone in each measure. But, I could have used two guide tones in a measure, one on beat 1 and the other on the beat 3. Other than what has already been discussed, there is no right or wrong way to do this. Basically, pick some chord tones, put them on the strong beat(s), and see how it sounds. Change or edit as you see fit!
