Holi · Rhythm · Sholay
Every Holi song is the same song, and that is the point
Dholak, a call-and-response chorus, and a woman threatening a man with coloured water. Fifty years of it, and the formula has not moved because it was never trying to.
Put the four best-known Holi songs next to each other and the family resemblance is almost comic. All four are in a fast six or a fast eight. All four have a dholak doing the same figure. All four are call-and-response, and in all four the woman has the upper hand in the lyric.
That is not laziness. Holi songs are not written to be listened to; they are written to be sung over, by a crowd that is already drunk and already throwing things. A melody that rewards attention would be wasted. What the form needs is a phrase short enough to shout back, and every one of these has exactly that.
Rang Barse is the outlier only in who sings it: Amitabh Bachchan, not a playback singer, on a lyric written by his father. The roughness is the reason it works. A trained voice would have made it a performance instead of a room.
Aaj Na Chhodenge is R.D. Burman doing the formula with better musicians, and Holi Ke Din is the same composer doing it again three years later at twice the scale. Forty years on, Balam Pichkari changes the instrumentation completely and changes nothing else, which is the strongest evidence that the shape, not the sound, is what the occasion needs.
The whole set is on होली.
