Cubic polynomial of the word “honestly”

Csound makes it possible to multiply an instrument times a function table. Here’s the function table for the pitch modification taken from the word “honestly” spoken by Hillary Clinton. This is a GEN06 function table, which allows you to specify a cubic polynomial through three points. It starts at 1.0000, and then goes up to 1.4419355 passing through 1.2209677. A sure sign of someone being nervous is pitch shifts like these.

f 761 0 257 -6 1.0000000 3 1.0000000 3 1.0000000 4 1.2209677 7 1.4419355 7 1.4935484 8 1.5451613 9 1.6384409 8 1.7317204 6 1.7204301 5 1.7091398 8 1.6978495

Which looks like this when graphed:

I then chose a pitch and Csound changes the pitch from that to follow the function table.

One thought on “Cubic polynomial of the word “honestly””

  1. This is fantastic work. The obviously many hours put into this turned into a very emotive piece of music – somehow you managed to capture the tragic nature of this sad piece of history.
