Animated Score Rite of Spring Fragment D in Adaptive JI for Brass Ensemble

Wednesday, July 20th, 2016

rite

I have been archiving past projects and I ran across this fragment of The Rite of Spring (French: Le Sacre du printemps; Russian: «Весна священная», Vesna svyashchennaya, ‘sacred spring’) and decided it would be interesting to render it in adaptive just intonation since that has been a recent topic of interest on the Facebook group Xenharmonic Alliance II. The video is an overlay of the score and the real time adjustments made by the Kontakt included factory script. I selected the factory brass ensemble which in my opinion rendered a nice version of one of my favorite passages of the piece. YMMV of course. You can find the video here for download.

NOTE: Sonar has a a very odd sense of accidentals if you do not explicitly apply a key.

Etude for Piano in 22 edo Superpyth [12]

Thursday, July 7th, 2016

etude22


Etude for Piano in 22 edo Superpyth [12] is another in my series of writing something playable for a piano student that has modest skills in a microtonal tuning. Since this tuning is in a 12 note per octave subset of 22 notes per octave the score is to be played as written after setting your sound source to the tuning below. For the sake of comparison the 12 equal version is here.

The full score is here. Academic performance in a setting where a fee is charged is allowed. Any other commercial use without my permission is not. Please write me for permission in such a case, I haven’t told anyone no as of yet 🙂

Piano Exercise in 15 Notes per Octave

Sunday, May 22nd, 2016

piano_in_15


Piano Exercise in 15 Notes per Octave is another attempt to write something playable for a piano student that has modest skills. The score is purposely scordatura because I think that notating in various microtonal accidentals is simply a burden when a person with a 12 equal midi controller and microtonal aware sound source set to 15 notes per octave (like a free Xen-Arts VSTi) can simply play the scare as if it was written for 12 equal but the sound will be in 15 equal and produce the microtonal music of the score. A note on the composition – it is a of a ABACC’ form with held chords as a sort of compositional ‘glue’.

Piano Version

Michael S. from the Facebook tuning forums asked me to improvise in his new tunings (there is another version on the way). In this case I used my Linnstrument and Pianoteq for both voice options. I left the 8 note tuning in “linear” mapping since with the Linnstrument there are no white / black key problems.

Nevadatite for Two Classical Guitars (24 edo) with score

Thursday, February 25th, 2016

Score for two classical guitars tuned a quartertone apart – Named after the rare mineral pictured.

Rendered from Sonar using two instances of “Strum 2.0” – higher quality though a bit less exciting to listen for me.

Rendered from Sibelius using two instances of Kontakt 5’s nylon guitar which added funky slides and some ugly slaps.

This was a proof of concept – I had to fight Sibelius to work with two instances of Kontakt to get the tuning right.

Spectral Greetings is a piece that started as a Linnstrument improvisation and then was harmonically filtered with Paul’s Extreme Stretch at the above frequencies to create a justly tuned spectral piece when all four frequencies were combined. The score is represented by the sound spectrum.

17 edo I-IV-V Cadences

Tuesday, December 8th, 2015

17triads
17 edo triads – framed in a perfect fifth are sus2 (212 cents), minor (282 cents), neutral (353 cents), major (424 cents), sus4 (494 cents) and then walked back down ending on a resolution of the sus4 – more on 17 edo
NOTE: all examples are scordatura – if you have software in 17 notes per octave and play these notes on a regular keyboard you will get these progressions.
The trade off is one of sacrificing clear notation for playability
145a
I root -IV 2nd inversion – V 1st inversion – I root
145b
I root -IV 2nd inversion – V7 1st inversion – I root
145c
I 1st -IV root – V 1st – I 2nd – IV 1st – V 1st (sorry for the missed F# – should be Gb)
145d
I 2nd -IV 1st – V7 1st inversion – I root
145e
i root -iv 2nd inversion – V 1st inversion – i root
145f
i root -iv 2nd inversion – V7 3rd inversion – i root
145g
i root -iv st inversion – V7 2nd inversion – i root

every example in one file

Discussion: The above illustrates the use of 17 edo within the context of common practice as developed for 12 notes per octave tuning. 17 works acceptably in this context. Adding a seventh or using inversions tends to soften the very sharp 423 cent major thirds. In the context of a minor key with the only major third being in the V to i the sharpness becomes an asset as a leading tone.

Fantasy for Piano Tuned to 10 edo (with score)

PDF of the score is available by clicking the picture


Fantasy for Piano Tuned to 10 edo started off as an exercise to break try to disrupt common rhythmic patterns. It starts out a bit mad but soon tones down. 10 edo is an interesting tuning because it doesn’t sound as foreign (to me) from 12 as one might expect.

clouded days for just intonation piano (animated score)

Tuesday, August 11th, 2015


best viewed at higher resolution.

“clouded days” was recorded directly into Sibelius 6 while watching the video, sort of – something I’m still experimenting with. The intent was to try to following the video and react musically to it. Frankly it was hard to do. After recording the piano I did fix some fat finger flubs. The recording and playback are at actual speed though this was recorded with Sibelius’ “Live Tempo” so the playing flows better than the score because there are unseen tempo changes. Also, frustratingly the pedaling I did was not reflected in the score…. and other oddities are there, too numerous to mention. However, in general, the score is much better than Sonar’s score. The animated score was captured by SnagIt and put together with Sony movie studio 13. I can’t take credit for the clouds though, only filming them.

A word about this tuning. It has a bluesy flavor right out of the box which is why I play the mostly diatonic run at the start. I found the tuning in the Scala archives. Below is Scala’s interval assignment. I can’t say it is readily apparent to me why the tuning sounds strikingly that way to me. But…. in the end its what you hear that matters.
