I went to a Chinese concert recently and was intrigued by one of the Chinese wind instruments Hulusi葫蘆絲 (photo below). It has a Calabash葫蘆 head connected to a bamboo body.

The bamboo has finger holes which the performer blocks/ unblocks while blowing through the mouth piece on the top. It sounds a bit like flute but as the Hulusi is made from Calabash, a full bodied fruit that has been emptied and dried. It has a rounder sound. Click here to have a look at Hulusi >>
