Dizi is a traditional chinese travers flute.
In china the declaration of tonality is different to europe. They don't sign the deepest note, but the note at the third hole from the bottom. That means a flute in chinese F is C-major (deepest note C).
We have a simple Dizi, black vanished light bamboo, one part
and a good quality Dizi: bitter bamboo, red string winding, two parts, with luck-knot and bag
Please ask which tonalities are actually available.
