In Carrefour I bought (for NTD60) a Chinese Whistle. It plays like a tin whistle - I can play some tunes not too fancy containing embillishments, rolls, taps etc
I looked up Chinese whistles on the internet but could not find a match
Anyway on the underside of it is a hole, that if I close with my thumb makes it sound like a C tin whistle. On the bottom is an additional hole that I leave open.
Does anybody know what these holes are for (perhaps Sandman)?
