Just Intonation vs Equal Temperment

Postby rainriot » Sun Apr 01, 2012 1:13 pm

Do you think that it would be helpful for Absolute Pitch Avenue and Interval Loader to have Just / Pure Intonation?

If I had a request it would be for aruffo to add a menu item to at least switch between just tuning and equal temperament. I think that it's a standard part of MIDI programming, am I wrong?

Also can I say "thank you!" to aruffo for the infinity interesting and entertaining writing on his site. :)

(I'm glad you like the site-- thanks!)

I'm not aware of a just-intonation option for MIDI..? But I have reason to believe that absolute-pitch development relies on the stablity of each pitch category. Although each pitch sound does need to become a category-- to have some tolerance for "sharp" and "flat" sounds-- the center to which that deviance is compared remains consistent.

For generating MIDIs in exotic tunings, you might look at Scala or Tune Smithy.

Just Intonation for Interval Loader

Postby JohnMagic » Sat May 04, 2013 6:35 pm

I too would much appreciate just intonation for the Interval Loader. Ideally one should be able to switch between equal temperament and just intonation, and then select key for just intonation. The advantages as I see it,
  • People with natural absolute pitch use just intonation
  • The harmony is better so it is easier to learn and hear when it in tune
  • Equal temperament is just a compromise in order not to have to retune the piano when changing key, nobody really think it sounds better
  • The differences between different keys is emphasized with just intonation
  • Lot's of classical works were written for just intonation (or similar temperaments), if you don't practice the various keys in just intonation you can't appreciate the choice of key for the classical works

Disclaimer: I don't really know what I'm talking about, this is just my idea formed by reading stuff on the Internet :lol:

Interesting ideas here. And I like the idea of being able to listen to just vs. equal temperament- both do have pros and cons though. Personally I think it would be easier on the user if they used the same tuning that their instrument does, for if they develop AP, it's more likely to be in the same tuning system than their instrument is in. For me, for example, my AP seems to default to 12-tone equal temperament since I grew up around a piano. However, just tuning works for me as well. There is a subtle difference between the two, certainly. The whole issue of blending with others and using just tuning was interesting when I joined a high-level chorus and got to sing perfect intervals against my choirmates, as well as blend when they weren't 100% on. Point being, that one tends to develop AP according to what tuning system they use. So for example, for a vocalist developing AP, using just intonation in APA could be excellent, while for a pianist equal temperament may be of more use (at least in the beginning).
Also, keys are identifiable and characterized based on chroma. Sure, just tuning may bring out some aspects of keys more and make other keys sound quite interesting, it's really chroma that characterizes keys. I feel a lot of composers (or at least I can vouch for myself as a composer) choose their key based on this chroma, although another source of key choice is practicality. For example, D flat major is not a practical key for stringed instruments to play in.
All in all though, this idea of a button for temperament does sound like an interesting idea. I'm intrigued by it and look forward to seeing what happens in this area of APA.
