Thanks to everyone who replied to my request. I didn't have time to reply so often, but its really appreciated.
I learned a lot from what has been said here. I am into shakuhachi for shakuhachi, and shakuhachiness and exploring silence and the mind and nature and... . Any detour into western music will be just for fun on an occasional occation. I took shakuhachi up about two yrs ago, and have absolutely no musical background, if I really wanted jazz, rock or something else I would have picked another instrument I expect that my many yrs of meditation and yoga will reward me somehow in my shakuplaying, will be fun to see!
Learning a little bit about music theory helped me understand that there is "more space" between certain holes and the shakuhachi, therefore we more reasonable have one more meri there. I expect to learn and understand more, but time is limited so 99.9 % of the time is devoted to practice traditionally what my teacher tells me - and there is enough universes in there to explore!!
When kids are playing in the grass, and we lounge in the sound, my friend (http://youtu.be/pvTX37ynAOI) takes out the guitar and I bring my woodenflute or Yuu, I will ask him to tune it to D, or open D dropped D tuning as he knows this much better me!
Can moderators decide if this thread is better placed in beginners section. _________________ -------------------------- I belive in life before death.
