Fretboard Biology Reference Appendix Available
We have had a number of requests for a reference appendix of diagrams presented throughout each Level to make it simpler to review the variety of chords, scales, arpeggios, and other items presented in each Level. An Appendix file has now been made available for download from the Unit 1 Practice module within each Level.
