In my piece, a video is used to capture the data and then sequences of numbers were selected to put together the score (letters are converted into numbers A=1 B=2 etc.) For instance, the opening sequence of the piece is 13 10 13 10 (1-core) then 9 6 5 7 6 9 6 5 8 5 7 6 9 (2-core). The 1-core sequence is the beginning of the video and the 2-core sequence was found at 2’47”. Converted back into letters they are: L J M J (1-core) then I F E G F I F E H E G F I (2-core). You probably can’t tell just by looking at the video, but each node is an intricately performed action on the horn using irregular and unstable states, such as a half valve pitch technique, split tones, irregular breathing, vocalisations, dynamics changes, wavering flutter and rapid alternations between single, double and triple tonguing. There are also theatrical elements such as delicately caressing the horn with a large white goose feather. And another where two people stand either side of a horn player each holding long pieces of black fabric tied to the outer tubing, and they walk around the horn player, slowly wrapping, ‘suffocating’ the player in the fabric while the piece is being performed. The outside performers move in a spiral formation, restricting and covering the player’s movements. The horn player needs to make the best effort to continue playing even with hand and vision restrictions as this process unfolds.
