The Intermediate courses are not what most would call intermediate! Most students would call them advanced, and to be fair, they are. I consider KNOWING the fretboard an intermediate step, rather than advanced. So don't feel bad. But do take each step fully, one at a time. Music requires that you DO the drills and not read about them. They are designed to make a musician out of the student. All of the basics are covered. The neck is to be understood and no longer a mystery to the student. Confusions are handled and technique is developed. The focus isn't necessarily jazz, as the information contained can be applied universally to any music style, but jazz tunes are explored for the purpose of applying improvisational techniques and for learning to use the chords we're working on. Chords are learned comprehensively and basic chord melody is explored.
It is also expected and required that the student know how to read music. If there are any hesitations in the students reading ability, the Reading Course is recommended and it is suggested that it be done in conjunction with the first Intermediate Course.
These are hefty courses. My private students pay $75 a lesson and it took 2 to 3 or more lessons to get what is given in one lesson here. And those students who applied themselves and did the lessons, improved dramatically as players.
