Surpetis
A shruti box (surpeti) gives a steady, continuous drone that helps singers and instrumentalists stay in tune during riyaz, teaching, kirtan, yoga and sound healing. Choose from small, medium and large sizes, 2 and 3 octave ranges, all-teak models and a harmonium-cum-shruti box.
Most models are tuned to standard A440, and we also offer A432 tuned shruti boxes for a softer, warmer feel.
See our harmonium FAQs for the difference between A440 and A432 tuning.
