Fictional nine-stringed instrument played by Gurney Halleck from the 1984 science fiction novel Dune.
Paul watched the rolling, ugly man set himself back in motion, veer toward the training table with the load of weapons, saw the nine-string baliset slung over Gurney's shoulder with the multipick woven through the strings at the head of the fingerboard.
Gurney laughed, and he swung into "Galacian Girls," his multipick a blur over the strings as he sang:
"Oh-h-h, the Galacian Girls
will do it for pearls,
And the Arrakeen for water!
But if you desire dames
like consuming flames,
Try a Caladanin daughter!"
