“Wendelstein 7-X” an impression for processed sound, brass and percussion in adaptive just intonation is a piece inspired by the first successful test of a large scale stellarator fusion reactor. Click on the graphic for more information. NOTE: this piece has a wide dynamic range

La cathédrale engloutie for Brass and Double Bass Ensembles Tuned in Adaptive Just Intonation is an adaptation of a piano performance of Debussy’s composition that I used Kontakt’s adaptive just intonation setting with “natural seventh” engaged. This sounds a bit off in places since using sustain to smear brass (as in the piano piece) doesn’t work too well, yet then again I think parts sound rather majestic. Your mileage may vary.
The ice is thin, the ice is thin –
the shore more distant year by year,
and nearly sixty since I left it now.
There is no going back again.
And I am old yet not so very old –
I bless the ice. I pray for cold.
Thin Ice is a piece for Alto (Christiane Offenbar in adaptive JI), Female Choir in 16 edo, Harp in 8 edo, bass drum and tamtam.
Fretless Classical Guitar Improvisation – to be honest I didn’t think the guitar was going to have as much sustain on fingered notes as it did and I ended up having quite a bit of fun playing with various JI intervals and a touch of 24 edo. The guitar cost only $20 at my local Guitar Center because it had Grateful Dead stickers plastered over it, perhaps in an attempt to hide the slight impact on the soundboard. But for that price I can remove stickers, live with cracks and gleefully remove the frets. This will probably end up being a harmonic series fretted guitar. I just put on new strings the day before so I have to tune the guitar a little here and there during the performance. The tuning I used is a modified Dante Rosati tuning of CGCGCC – the duplicated C’s on top are because the high tension string set just wouldn’t make the high G without breaking. Luckily breakage is a lot easier to deal with on a classical. You can see from the above pictures that I back filled the kerfs (fret slots) with plastic wood and sanded. It looks sloppy but that excess is actually filling in the slight dents in the wood – I used a straight edge to remove the excess plastic.
Here is a comparison of La messa de Nostre Dame Sanctus in different tunings as rendered via Kontakt’s choir sample set. The midi file I used is here. (S.Takahata transcribed the piece to midi) The score with Sonar’s brain-dead accidentals is here.
First version uses Kontakt’s built in adaptive JI (adaptive JI = dynamic pure tuning like this live example video that shows the changes in intonation in real time https://www.youtube.com/watch?v=WB6I6EWWdr4 )
