Cuechtli · the shells worn to walk

It is worn, not played

This is the difference that sets it apart from all the others. The cuechtli is not held in the hand: it is small shells hung from leather strips, sewn to clothing. They sound because whoever wears them walks.

Sahagún describes it in Book II, speaking of the citlalli icue skirt of Ilamatecuhtli in the veintena of Títitl: when she walked, he says, «hazían gran ruido que se oían lexos» — they made a great noise that was heard from far off.

It appears in four veintenas: Tecuilhuitontli, Teotleco, Títitl and Izcalli.

What exactly was measured

Synthesised from original recordings. The process was this: a replica of the instrument was played and recorded, and from that take the parameters the engine uses were extracted by analysis.

A replica is built today, by someone with their own view of what measurements and materials the original had. Its timbre is that replica's — not that of a museum piece, and still less of one that sounded in Tenochtitlan.

That is why the timbre is declared measured and not attested: the measurement started from a real object, and that object is recent.

The original takes are not kept. What is published here is the sound the engine produces from them, with its fingerprint so that anyone can check it is the file it claims to be.
