PaulTheOwl/Ripper/MxBv As a massive fan of Meshuggah, Orbital, Behold The Arctopus, Aphex Twin, Orthrelm, King Crimson and a bunch of others that are amazing at counting rhythms and doing odd things within and around those patterns, this album makes my brain feel happy and does all the things that the above mentioned artists do in a stripped down playful electronic manner.

Listen to the melody / the riff, get into it, and then realise just as you were really feeling it, it's been changed slightly. A brilliant record.

Jean-Paul DuQuette Strangely listenable electronic music math experiments. Favorite track: A1. 97/111=0.873873....

gachaluna i like how all the tracks have the same theme but how different the tracks seem Favorite track: B1. 1/7=0.142857....

aquasnowetto Cool method for making music and maths connected Favorite track: A5. 1/17=0.0588235294117647....

Cassette HK The idea (of encoding digits into notes) is wise, unique and creative! Some songs are unexpectedly melodic (and hypnotic), while some are droning.

1.	A1. 97/111=0.873873... 01:48	lyrics
Algorithm: 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.
2.	A2. 4/7=0.571428... 04:33	lyrics
Algorithm: 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.
3.	A3. 7/9=0.777777... 01:06	lyrics
Algorithm: Samples of sevens, pronounced in German, French, Spanish and Chinese, were cut and pasted, forming a stream of sevens in different languages.
4.	A4. 1/3=0.333333... 03:25	lyrics
Algorithm: A single note, representing 3, were played continuously. Various synth configurations were changed, forming a droning soundscape.
5.	A5. 1/17=0.0588235294117647... 02:36	lyrics
Algorithm: A stream of notes were played continuously without rest, forming a sequence of cyclic numbers with degree 16.
6.	B1. 1/7=0.142857... 03:25	lyrics
Algorithm: 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.
7.	B2. 23/99=0.232323... 02:10	lyrics
Algorithm: 2 and 3 were encoded as rhythms of groups of two and three notes. A tribute to Kraftwerk’s Trans-Europe Express.
8.	B3. 1/41=0.02439... 05:18	lyrics
Algorithm: 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.
9.	B4. 3/11=0.272727... 02:53	lyrics
Algorithm: The 2 and 7 notes were played repeatedly with varying rhythms.

about

<Music For Recurring Decimals>
by Epsilon-Delta

Studying Mathematics and Engineering in Universities, Hong Kong-based electronic musician Epsilon-Delta uses synth to represent Mathematics musically, forming a unique soundscape of “MathSynth” music.

In his debut experimental concept album “Music for Recurring Decimals”, Epsilon-Delta created soundtracks for cyclic numbers/ recurring decimals (E.g. 0.333333...) by encoding them with notes and/or beats, making various “number pattern driven” monotonic minimal compositions.

“Music for Recurring Decimals” is the maiden production of 433 Records, a Hong Kong label which upholds John Cages’ famous manifesto: “Everything We Do Is Music”.

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.
