The taus, Persian for peacock, is a large bowed instrument with a long fretted neck and a body carved in the shape of a peacock, its head and beak at the base and sometimes real feathers set into it. It has four or five main strings and many sympathetic strings.
Sikh tradition credits Guru Hargobind with its invention, after hearing a peacock sing; others link it to Guru Gobind Singh's court at Anandpur. It became a central instrument of Sikh kirtan, played by court musicians and later by the Namdhari Sikhs, who preserved the tanti saaz when most gurdwaras turned to the harmonium.
The dilruba, a lighter version without the peacock, was developed later for easier playing. Both are now at the heart of the revival of classical Gurmat Sangeet.
