This is a work in progress. It’s a bit long now. I’ll have to figure out a way to shorten it up a bit.

Martin Luther is credited with this hymn in 1529. Today i present a simple statement of the opening few notes. Familiar? I can’t decide if the penultimate chord, on the word “Our” should be
D 10/9 - F# 25/18 - A 5/3
or D 9/8 - F# 45/32 - A 27/16.
Decisions, decisions. Here it is as the latter.

I just noticed this video of a 60×60 concert in NYC with my short piece for
bassoon, bent wire spring, and percussion board.
60×60 Dance (2008 International Mix) performed at the World Financial Center Winter Garden in New York City on Friday, November 14, 2008. Music: Prent Rodgers Dance: Elana B Cohen
The rules stipulate that all compositions be no more than 60 seconds in length, which are assembled into concerts of 60 at a time. The whole operation is run by Robert Voisey. More information here: http://www.VoxNovus.com
For this 2008 performance, Robert enlisted a group of very talented dancers. More here.
He has also worked with Aaron Krister Johnson on a microtonal 60×60, which I think has been assembled for a concert in Chicago that Aaron is organizing for April 27th MCA Chicago 60×60/UnTwelve mix.

Update: Here is a picture of the “Bent Wire Spring”, an instrument I built back in the 70’s. It is a block of birch, about 3/4″ by 4″ by 10″, with a groove cut out for an angle iron fabrication with mid-gauge piano wires coming out. In the middle of the angle iron is a hand wound magnetic pickup that goes to an amplifier. The piano wires are bent into random shapes. You pluck the wires and each makes its own enharmonic spectrum with deep bass tones and an assortment of harmonics. Click the photo to enlarge. 
I worked with CDBaby (and paid them $45) to put my last CD up on iTunes. It took a few weeks, but you can find it now on iTunes. It’s an experiment.

This is a final version of this piece

O Sacred Head, Now Wounded is one of my favorite hymns. It started life in the 11th century as a poem, later set to music. Bach harmonized it around 1734.
This version is scored for mallet instruments and woodwinds, specifically marimba, vibraphone, finger piano, flute, oboe, clarinet, bassoon, and sine waves. The basic idea is to keep the marvelous Bach harmonies but stretch it out a bit. Each chord is repeated or held and arpeggiated before moving to the next one.
The tuning is low integer just, approximated in 72 EDO. You can see the specific ratios used in the chart above. Click on the image to make it bigger.

This still needs a lot of work, but the basic outline is done. This piece has 63 chords, compared the the previous one with only 37. The specific deconstruction technique I’m using doesn’t scale very well: it takes lots of keystrokes to do each manipulation. The basic idea is allowing a chord to arpeggiate for as long as it wants to before moving to the next one. Scored for woodwind quartet and mallet instruments for now.
This is a work in progress.

Revised to increase the variability of the attack time. There’s a variable in each note that adds a few random milliseconds on to the start times of notes. I had it in place for the marimba, and now it’s in place for the vibe, finger piano, and harp as well.
