The Cellular Approach is a practical method for developing the ability to create convincing jazz solos in a wide variety of playing situations.
It takes actual jazz lines recorded by master players and then slices them up into small "cells" that can be re-combined into longer lines to fit almost any harmonic situation.
This enables the player to improvise his or her own lines that sound just as interesting and melodic as the masters without resorting to simply copying others. Fingerings and string choices are often given too, making it particularly valuable to guitarists who want to actually master their instrument.
