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

Semaphore[9] in 19-EDO

The scale is a chain of half-fourths. Here the melody always is a 5-note subset of the full scale to match the underlying chord.

The lyrics are actually in English but not intended to be easily intelligible.
