Flute received and I can not put the thing down.  Music has been an untouchable skill for me for some time.  Keeping it simple with the pentatonic makes life easy and I will play this thing after biking or hiking out into the middle of the woods.  On the technical side, your tuning is letting me explore the ridiculous range of this instrument through half-hole trickery which lets me try my hand at playing some favorite tunes.
