Cymbals

- There are various sorts similar to the ones found on Urth.

Czehar

- Musical instrument having 8 strings, it is held across the lap when sitting cross-legged and is played with a horn pick

Flute

- Same as Urth flute and the players always keep them polished.

Kalika

- A six-stringed instrument; it, like the czehar, is flat-bridged and its strings are adjusted by means of small wooden cranks; on the other hand, it less resembles a low, flat box and suggests affinities to the banjo or guitar, though the sound box is hemispheric and the neck rather long; it, too, of course, like the czehar, is plucked.

Kaska

- A small hand drum.

sticks

- Played by sliding a polished tem-wood stick across its surface.
 

Tabor

- A small drum.

Tambourine

- Bits of metal on wires; gourds filled with pebbles and slave bells mounted on hand rings.

Zills

- Finger cymbals.

Some interesting quotes from the scrolls:

I have never seen a bowed instrument on Gor; also, I might mention, Ihave never on Gor seen any written music; I do not know if a notation exists; melodies are passed on from father to son, from master to apprentice.
--Nomads of Gor, pg 153

Among Gorean musicians, incidentally, czehar players have the most prestige; there was only one in this group, I noted, and he was their leader; next follow the flutists and then the players of the kalika; the players of the drums come next; and the farthest fellow down the list is the man who keeps the bag of miscellaneous instruments, playing them and parceling them out to others as needed. Lastly it might be mentioned, thinking it is of some interest, musicians on Gor are never enslaved; they may, of course, be exiled, tortured, slain and such; it is said, perhaps truly, that he who makes music must, like the tarn and the Vosk gull, be free.
--Nomads of Gor, pg 154
