  1. Tetrachord Scales-Part 1-Randy Johnston


    Always loved Randy’s playing-this is my first exposure to his teaching. Have to say, his approach makes jazz guitar a whole lot simpler and much more logical-not necessary to learn endless fingering patterns. This system allows you to actually play much more melodically, which is really what it’s all about!

  2. Very helpful, taught in a relaxed, fun manner


    Randy seems like the kind of guy you could easily talk to over drinks between sets at Fellini’s in Charlottesville (oh, wait – I DID do that!) This is a great lesson that teaches a concept that I wish I had learned years ago. In just a few short minutes I feel like I’ve learned an easy way to escape the box pattern of playing on the fretboard. Not to mention an easy way to play a diminished scale! That alone was worth the price!
    Really looking forward to part 2 (and beyond).

  3. Insightful


    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.

  4. 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.

  5. Tetrachord Scales --Part 1


    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.

  6. Fantastic!


    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.
