Shruti Box (Indian Drone)
Generate hypnotic Indian classical drones using hand-pumped air and fixed pitches
The Shruti Box is a rectangular instrument used in Indian classical music to provide a constant drone foundation for other instruments and singers. Operated by a hand pump, it produces continuous, meditative drone tones on fixed pitches. The minimalist design and meditative function make it perfect for yoga, meditation, or as an accompaniment to vocal practice. Unlike melody instruments, the Shruti Box encourages deep listening and harmonic exploration rather than technical prowess.

Repetitive, rhythmic pumping action is soothing and meditative. The fixed drone removes decision-making, allowing focus on listening and breathing.
The Shruti Box has been used in Indian music for centuries, helping musicians practice ragas (melodic frameworks) by maintaining the harmonic foundation.
