Studio J: John deLaubenfels' Just Intonation project







I can't hear 12-tone music (the octave divided into 12 equally-spaced intervals) any more, especially piano music,
without missing the sound of intervals well-tuned, their harmonics aligned. At the bottom of this page I experiment with
retuning existing works, with somewhat limited success. So, to experience music that is well-tuned from beginning to end,
I've been composing. Here's a sample (listen with headphones if possible):

Project Retune: the retuning of General MIDI files to adaptive quasi-Just Intonation (qJI).

Hardware requirements: to play the following files, you need General MIDI (GM) capability. Most computer sound cards made in the last five years have this, as do most stand-alone modules in the same time period. If in doubt, give one of the tuned files a try. If notes are missing, you probably don't have GM. If notes seem poorly tuned, see below.


June 27, 2001: new results using "melodic springs":

Gershwin "Rhapsody in Blue" (2-hand piano reduction), sequenced by Gary D. Lloyd:
rh-n-blum.zip Positive, negative, and zero-strength melodic springs with 7-limit adaptive tuning.

Chopin "Fantaisie-Impromptu", Op. 66, sequenced by Larry Ellis:
lechi4jm.zip Positive, negative, and zero-strength melodic springs with 5-limit adaptive tuning.

May 23, 2001: David J. Finnamore "Romantic Sixth Chords Experiment", sequenced by David J. Finnamore, copyright (c) 2001 David J. Finnamore.

May 8, 2001: Chopin "Fantaisie-Impromptu", Op. 66, sequenced by Larry Ellis:
lechi4j.zip Original and some tunings
lechi4jx.zip More tunings

Feb 8, 2001: Bach/Busoni "Chaconne in D-", sequenced by Bunji Hisamori, with chorus commands removed:
b-b-bj.zip

Jan 31, 2001: Mozart Sonata No.2 in F, K.280, sequenced by F. Raborn.

Here's some of the recent (December 2000) multi-voice stuff I've been doing:
caravan.zip
pearls.zipA String of Pearls"
KeyedSeqs.zipKeyed instruments restricted in tuning.
verk-nac2.zip:Monz's sequence of Schoenberg's "Verklarte Nacht", 01-06-01




Having trouble with these sequences: do they sound badly out of tune? You might have a different pitch bend range. Try downloading this to check your bend range; you should hear E, F#, and D. Try downloading this to fix the problem. Send me e-mail and let me know how it goes...


And now for something completely different:
Political rants


The following is version 1.000 of JI Relay, April 4, 1999... A newer version, containing some of the tuning in Project Retune, above, was hoped for by this time, but has been postponed, sorry!
