    Finally! An explanation of how to determine intervals on a guitar fretboard that makes sense. Clear, concise, straight forward. This should be the de facto presentation in every music theory book for guitar. Thanks a million!

    I have had a headache trying to learn from to many so called experts. This is clear and I actually understand it. Thank you so much! I agree with Jack ?
