The swarmandal (Hindi: स्वरमण्डल [s̪ʋərməɳɖəl̪]), surmandal, or Indian harp is a plucked box zither, originating from India, similar to the qanun that is today most commonly used as an accompanying instrument for vocal Indian classical music.

[1][3] The strings are hooked in a nail lodged in the right edge of the swarmandal and on the left are wound around tuning pegs which can be tightened with a special key.

A sharp 1⁄2-inch (13 mm) ridge on both sides of the swarmandal stands a little apart from the nails on which the strings are tightened.

commented that good performances on the instrument were rare, because it was difficult to play and, at the time, expensive to buy.

After travelling to India in late 1966, George Harrison introduced the swarmandal into the Beatles' sound on their 1967 single "Strawberry Fields Forever".
