I had a great practice session yesterday. I spent an hour playing the minor second between low B-flat and low B like Steve Lacy advocated in the chapter Tight Corners of his book Findings. It was not boring at all. Loud/quiet, vibrato/no vibrato, tonguing/not tonging, etc.; it's all there in the minor second interval. I've been reading a lot about shakuhachi players and listening to their music. They have inspired me to blow Ro-buki. I usually play long tones for about half an hour per day anyway, but yesterday was a special practice. Focusing on the sound, the breath, and the tone of just two notes for an hour was very worthwhile. I plan to do this practice once per week with different intervals. If you haven't tried this, I suggest that you do.
