Shruti-Box: Drone Instruments for Practice and Accompaniment

Find shruti-boxes built to provide steady drone accompaniment for vocal practice, meditative music and ensemble rehearsal. This overview covers different types—hand-pumped, electronic and portable—plus features to consider for reliable pitch support.

Key characteristics

Shruti-boxes produce a sustained drone that supports pitch training and harmonisation. Stability of the drone, tuning flexibility and portability are primary selection factors.

What to look for

• Tuning options: Adjustable pitch controls or tuned reeds let you match vocal ranges and scales.
• Power and portability: Hand-pumped boxes suit acoustic settings; electronic models offer sustained, maintenance-free drones.
• Build quality: Sturdy reeds or reliable electronic circuits ensure consistent tone.
• Accessories and extras: Some units include multiple pitches, foot-pumps or cases for transport.

Choose a shruti-box based on use: acoustic boxes for traditional feel, electronic units for long practice sessions or studio use. Electronic models can be especially useful for teachers and performers who need consistent tuning and extended drone duration; you may find refurbished or clearance electronic units at a lower cost. Test for pitch accuracy and tonal richness, and consider how the instrument integrates with your practice routine. A well-chosen shruti-box becomes an essential tool for singers and instrumentalists seeking steady, tunable support.
