Instrument Study: Structure, Tuning, Maintenance and Technique
Structure and tuning (sitar model)
A sitar has a tumba (resonator), dandi (neck), tabli (soundboard), jivari (bridge), pardas (frets), and strings including baj tar, jod tar and cikari. Tune baj tar to Sa, jod tar to Pa (or Ma when the raga requires), and cikari to the upper Sa. If Sa is C, the common tuning is C-G-C'. Tune by comparing octaves and fifths, then check with a tanpura or electronic drone.
Maintenance and technique
Keep the instrument in its case, control humidity, change strings before they corrode, check the jivari for buzz, and never force a stuck peg. Right-hand technique uses a mizrab with da (inward) and ra (outward) strokes; left hand produces meend, kan and murki. Adapt these headings for tabla (dayan/bayan, syahi, gatta), flute (cork, embouchure) or violin (bridge, pegs, bow).
Worked example
If a sitar's Pa string sounds dull, first check the jivari contact and string gauge, then tune the jod tar against the baj tar's Pa. Do not tighten all strings to Sa: that destroys the drone and the instrument's designed register. For a raga without Pa in aroha, the jod tar may still be tuned to Pa as a drone; the raga's phrase, not the tuning, decides its use.
Traps
Tuning every string to Sa; over-tightening; ignoring bridge placement; describing tabla's dayan and bayan as identical; giving generic 'practice daily' instead of structural detail.
