Thought I'd give this method a look-see. I have not started it yet. One thing that Claude Gordon stresses, "It is absolutely essential that you practice these routines in the prescribed manner." So my question is, if I were to try the Systematic Approach, would I play anything else? The first lesson (repeated daily for at least 7 days) is long tones down to your lowest pedal tone, rest 15 minutes, long tones up to your highest note, then rest at least one hour. OK, then what? I'm not sure how I would work this into the rest of my playing day.
