Algorithmic Choral Compositions

Dear All,
 
I'm looking for algorithmic choral compositions that are not canons or rounds, and not compositions by Arvo Part! Already have an ample sampling of those.
Looking forward to your suggestions!
 
Best,
Judith

Hi Judith,
Not sure if my SSA piece "Winter Stars," will qualify for you---
but it's 4 verses..... all parts are derived from the opening soprano melody.

This may demonstrate my lack of training here...but what exactly do you mean by algorithmic as it relates to choral music? Repeated patterns and melody lines?
on August 25, 2013 11:12am
Hi Joy,
 
I mean that there is a constructive principle according to which the elements of the music are created. Rounds and canons are good examples, but I'm looking for other types - for
instance, generated by a computer algorithm that chooses pitches according to a markov chain. Or, every note is extended by a certain amount, or the number of notes is specified by some kind of mapping.

ah! I was wondering if that's what you meant. Thank you!

John Tavener's "The Lamb"?

A piece based on the Golden Ratio and the Fibonacci sequence. The sequences forms the harmonic progression throughout the piece.

There are other mathematical connections as well. Is this what you were thinking?

OK, now that's SERIOUS geekdom!

Hi Timothy,
 
Very interesting, and yes! Thankyou.

Hi Judith,
 
My friend David Stutz is a mathematician, composer and top-notch singer here in the Portland-Seattle area. I recorded a set of songs for him called Iolet (a CD to accompany Neal Stephenson's book tour for "Anathem"). It consisted of mathematically-based choral compositions, including a derivation of the quadratic formula, and he did a recent installation project on Turing. He is brilliant, and his music might be just what you are looking for. See his website here:
 
 
You can contact him there. Hope this helps!

Thank you, very intriguing!

Judith, I am interested in such compositions too. Outside the area of choral composition have you suggestions for some noteworthy compositions/authors? A more specific question: with "algorithmic" do you mean a composition totally determined from some initial "seeds"?
on August 27, 2013 10:03am
Hi Fabio, 
 
Well, initial 'seeds' is one option. Basically, I mean a composition worked out according to a strict constructive principle, computer generated or not.  I'll reply off list to your larger question, as there is a large field of work in this area. 
 
All Best,
Judith

Prof. Shatin,
 
You might be very interested in Mark Timmings' Narvaez Bay (Tidal Predictions for 2012) in which the music reflects daily tide levels, lunar cycles and solar equinoxes and solstices.
 
If you wish to contact me directly, I can put you in touch with him.
 
Sincerely,
