Epsilon-Delta – Music for Recurring Decimals (Cassette)

Algorithms
—————

[Side A]

A1. <97/111=0.873873…> (1:48) A base note was chosen in the sequencer, and notes were set 3,7 and 8 semitones above the base note. The 378 sequence was played repeatedly, and then the whole track was reversed, forming a stream of 873873 notes.

A2. <4/7=0.571428…> (4:33) A base note was chosen in the sequencer, and notes were set 0,5,7,1,4,2 and 8 semitones above the base note. A few rest notes were set after the 0571428 pattern. The sequencer was played with the varying number of rest notes, resulting in a change of length of each 0571428 pattern.

A3. <7/9=0.777777…> (1:06) Samples of sevens, pronounced in German, French, Spanish and Chinese, were cut and pasted, forming a stream of sevens in different languages.

A4. <1/3=0.333333…> (3:25) A single note, representing 3, were played continuously. Various synth configurations were changed, forming a droning soundscape.

A5. <1/17=0.0588235294117647…> (2:36) A stream of notes were played continuously without rest, forming a sequence of cyclic numbers with degree 16.

[Side B]

B1. <1/7=0.142857…> (3:25) A base note was chosen in the sequencer, and notes were set 1,4,2,8,5 and 7 semitones above the base note. The C key (base key), being encoded as 1, was pressed, playing the 142857 sequence in C. F (representing 4), D (representing 2), C’ (representing 8), G (representing 5), B (representing 7) were then played on top of the basic C pattern.

B2. <23/99=0.232323…> (2:10) 2 and 3 were encoded as rhythms of groups of two and three notes. A tribute to Kraftwerk’s Trans-Europe Express.

B3. <1/41=0.02439…> (5:18) The sequence was set in a way similar with the algorithm mentioned above, but notes were intentionally blurred in an inaudible manner, forming an ambient soundscape.

B4. <3/11=0.272727…> (2:53) The 2 and 7 notes were played repeatedly with varying rhythms.
