For about a year I have played the Japanese bamboo-flute Shakuhachi, not made from bamboo but PVC. When I get above the high D I will consider a teacher and a real bamboo-flute.
Mine looks like this (and is bought here if anybody should like one)

While the real flute looks like this.

Normally the Shakuhachi is used as a solo instrument as you can see in the clip below, but is can be used in many connections. Only thing is that it is a 5 tone instrument tuned in what is called pentatonic minor. I can play the notes in between but you need only cover half or 1/3 of the holes, while moving your head back or forth while changing the air stream. But many tunes are actually more or less written in pentatonic minor most famously Gerswins Summertime
