For Herman: A question about the porcupine ouverture

Hi Herman,

somewhere on your website, I found a few words stating something about your porcupine ouverture being played in 15-equal. If this is the case, then I'm asking: Do you also have a 22-equal version? I would love to hear it.

Thanks in advance.

I don't have a 22-equal version; actually only the last chord progression is in porcupine temperament, and that fact was discovered after I'd written it. (Which is how the temperament system got its name.) It was someone on the tuning list (I believe it was Paul Erlich) who observed that the porcupine chord progression also works in 22-ET.

However, I do have MIDI files of the final chord progression in various porcupine ET's including 22 on my web page.

There's also a continually rising 12-ET version which demonstrates that 12-ET is not a porcupine temperament.

I took the opportunity to revisit this page. I think the 22-ET
version best balances harmonic and melodic concerns (15-ET is
best for melodic alone).
