Cithrinchen
The Cithrinchen or Bell cittern was a distinctively shaped instrument of the renaissance and baroque periods. It was usually strung with doubled courses of thin, light tension brass or steel strings. It usually had 3 soundholes and 5 courses of strings. It was popular in Germany, England and Sweden.
Most such instruments built nowadays are reconstructions of historical instruments, or modern mandolin-type instruments which simply use the same body shape as the historical Cithrinchen.
