Mutations [disquiet0281] by dascott

I *really* had fun with this project! Where do I begin? First, the assignment called for a short pattern of musical notes played as a palindrome. I went several steps further.
I created a 9-note pattern in C which purposely plays all 7 notes in the scale plus 2 repetitions. Played as a palindrome this gives a 17-note series with seven unique pitches (I love primes!).
Next, the beat durations of the 9 original notes form a palindrome over the nine: 1,1,2,3,5,3,2,1,1. So this rhythmic palindrome repeats twice over each single repetition of the pitch palindrome. Some of you may notice the numeric sequence for the durations -- I brought Fibonacci in for the fun.
Then I created two additional 9-pitch lines in the same key and same duration pattern which harmonize with the original line, so now I have 3-part palindromic harmony! All these are played back using lovely pianissimo piano samples I got from the University of Iowa Electronic Music Studios.
Next, the assignment said to "add notes in its midst as it proceeds". Did I mention that I am creating this whole thing algorithmically with an RTcmix script? I added a chunk to my generator which, with odds of 1-to-50, splices a new pitch randomly into *one* of the three lines (pushing the existing ones to the right). These new pitches are all below or above the range of the original 3-part harmony, and may or may not be in the same key, and are all played with *fortissimo* piano samples! This makes each note set gradually longer and longer, so each line's pattern takes longer and longer to repeat, but the original 9-value duration palindrome keeps steadfast throughout.
The resulting effect is a gradual corruption (buildup of unfriendly mutations) of the original. Everything was done with a single RTcmix script. I really had no idea how it would turn out until I let the script run!
