The Shah Kaman
The shah kaman is a magical instrument created by Peter Biffen (www.spikefiddle.com) from Australia.
He took inspiration from the traditional 4 string Persion kemenche, but added strings, making 5 playing strings and 7 sympathetic strings.
The sympathetic strings run in a channel under the fingerboard. This design was developed in collaboration with the Iranian Master Kamancheh player Kayhan Kalhor. Kalhor named the instrument Shah Kaman, which translates into English as King of Kamanchehs.
