The musicians were free

“The musicians were free. Musicians on Gor, that is, members of the caste of musicians, are seldom, if ever, enslaved. Their immunity from bondage, or practical immunity from bondage, is a matter of custom. There is a saying to the effect that he who makes music must, like the tarn and the Vosk gull, be free.”

Kajira of Gor, p. 297
