For more advanced players, if you don't feel totally confident when improvising on the guitar, these courses will help you.

This course can be taken with an acoustic or an electric guitar.

Joe is playing an electric guitar throughout the course, but teaches higher and lower positions of the upper shapes, to allow for playing on an acoustic with no cutaway.

A level 3 course is tentatively planned for late 2026.  The level 3 course would cover the harmonic minor, melodic minor, diminished and altered scales, for soloing over jazz based material.
