Build Lines around Familiar Chord Shapes
When improvising, it is important to be able to outline the harmony of a song with single-note lines. We can start to work on improvising through a progression by creating lines that are found, for the most part, within a familiar chord shape, like the common Cm7 chord voicing in Example 1. Keep that shape in mind as you look at Examples 2 and 3, which illustrate the arpeggio and chord scale respectively.
Try to think of these examples as â€śfilling outâ€ť the basic sound of the Cm7, and notice that each note of the original chord shape is represented.
