"Xenharmonic" music with alternative tuning (e.g. Just Intonation, Bohlen-Pierce, Wendy Carlos scales). Also some noise/concrete music, and a few otherwise typical pieces with a single odd aspect such as uneven rhythm.

Mohajira improv

This is a chiptune-type piece I wrote in 2009, based on my daughter's imaginary characters (played by her fingers, acting as puppets). It uses Csound to evoke something approaching an 8-bit style (purests may disagree, since I used band-limited oscillators!)...neverthess, I hope you enjoy this piece.

Puhlops & Laugua's Big Adventure

A slow, graceful piece written for a 19 edo piano. You can clearly hear how 19 EDOs major and minor chords are FAR more in tune which is why the ninth sounds like an essential part of the chord in this piece.   

Mostly diatonic with occasional polytonality  

Moon - Nocturne for 19 EDO

This track was written to demonstrate the harmonic possibilities of using higher harmonics freely whenever the composer wishes, without the bounds of a traditional scale, but within the bounds of major/minor/seventh harmony. It is also quite funky!

Harmonics of 11ths, 13th, 23rds etc are prominent in this composition, without being overwhelming in their unusualness. The highest prime harmonic used was the 127th harmonic in the final melody! E#''' was also used (125th harmonic)

It was written using a new notation system which has been devised to make accessing higher harmonics as intuitive as possible (it still takes a bit of getting one's head around!). Please contact me if you would like to see the score written in this notation system, or for details about how this notation system enables interesting harmonic composition outside of the bounds of the Western 12-note scale to be realised.

It qualifies for chiptune since although it is (much to my shame) 16-bit 44100Hz audio instead of the pure 8-bit, the sounds were synthesised from scratch using modified sin/saw waves, with a bit of band-limited noise thrown in for good measure. The synth took as input CSV 6xN matrices as sequence files, and processed in Octave/MATLAB to give MP3 output which you hear here.

update 10th Apr 2015:

Here is a brief description of how the MP3 track was generated:

Just Intonation Notes (1/1 4/3 7/4 etc) <-> New Notation System (C F `Bb~7 etc) which is easier to read than pure numbers and where the letter corresponds (roughly) to the position in the 12ET scale
-> Excel block of chords and melody notes for visual presentation to composer (.txt)
-> Excel long (~1700 columns) of calculated note letters, frequencies, note lengths, etc
-> Excel final sequence file with 6 columns: channel, start time, frequency, note length, loudness, stereo position (.csv)
-> Octave/MATLAB code to take the 6 columns and turn them into chiptune (.mp3 or .wav)
-> Sometimes extra post processing in Audacity for final .wav

Boris Bunnik dons his Hexagon scuba gear before diving into electronic abstraction and aquatic electricity. Counter Utopia brings together three works of machine textures. “Cerebral Trauma” is submerged in a simmering liquor of smelted metal, molten melodies bubbling to the surface as ball bearings fizz and rattle. Industrial experimentation undercuts the entire EP. Soulful chords are stretched, contracted and contorted against the clean percussion lines of “Utopia.” Machines echo in the finale. Gears groan against a backdrop of soaring synths and pulsations in the depths of “Paranormal.”

Ok my new album 'Harmony Hacker' is out! Here's a track in the Bohlen-Pierce scale. Bohlen-Pierce is one of the wackiest microtonal tunings discovered.

Ask Yourself

hi i occasionally post bits of ""music"" here.
also anything labelled with another artist name is definitely by that artist, and not by me.
