    Helpful perspective on scale fingerings. Shows how to simplify the fretboard by seeing scale position fingerings in terms of combinations of their simplest components. Looking forward to the next part of the class.

    Simple and effective


    Any help that simplifies this “stupid” instrument is welcome. I think that We try to overcomplicate simple things. Great players play in a horizontal way not a pure vertical as normal pedagogy teaches.

    Thanks, Randy!

    This concept immediately added to my understanding and gave me things that I can use in my improvising today!!! Very clear presentation of a new way of seeing modes and scales.

    Brilliant! Absolutely brilliant concept and teaching. I love Randy’s playing and concepts and teaching. He is so concise and logical in his teaching. Everything makes sense and easy to learn. I can’t wait to work with this concept. I’m a semi professional player of many years, and I’ve never come across this concept before. Just brilliant. Highly recommended. Can’t wait for the second part and more classes from Randy. He reveals these secret gems that I find enhance my knowledge and playing.
