Wow that's pretty amazing, it sounds like you have a bright little boy! And so interested in playing <img src="i/expressions/face-icon-small-happy.gif" border="0">
To answer your questions yes I have played since transplant, in my senior year (the year after transplant) I actually made it to honors band <img src="i/expressions/face-icon-small-happy.gif" border="0"> Since college has started I haven't picked up my flute <img src="i/expressions/face-icon-small-sad.gif" border="0"> since they really don't have a band here and I'd have no clue where to practice without bugging my roommates, though I have been looking for other places to play.
How I kept my flute clean. Directly after Transplant ( I was a bit paranoid ) I took my flute to the nearest music center and had it stripped, cleaned, repaired, repadded, the works. This can only be done a few times in an intstruments life because what they do is each time they clean it they remove a small layer from the inside the flute, if they do it too many times the sound changes way too much and the flute becomes brittle. Anyway, after that I just cleaned it out after practice and never let anybody play on it. The whole flute cannot be like... dunked under water and cleaned because of the pads on the flute are made out of, believe it or not, onion skin. (I'm not sure about trumpets because I think the pads are removable) Well... wow, I typed more than what I thought, I hope this helps <img src="i/expressions/face-icon-small-tongue.gif" border="0">
