A canon generated using algorithmic composition. This means that the music is composed by a computer algorithm. 

You can get some explanation and the full code to the program on my blog: 
http://a-touch-of-music.blogspot.com/2013/08/algorithmic-composition-generating.html
The algorithm used the following inputs:

  # define a chord progression that serves as basis for the canon (change this!)
  chords = "C F Am Dm G C"
  # scale in which to interpret these chords
  scale = music21.scale.MajorScale("C")
  # realize the chords using the given number of voices (e.g. 4)
  voices = 5
  # realize the chords in octave 4 (e.g. 4)
  octave = 4
  # realize the chords using half notes (e.g. 1 for a whole note)
  quarterLength = 2
  # number of times to spice-up the streams (e.g. 2)
  spice_depth = 1
  # how many instances of the same chords to stack (e.g. 2)
  stacking = 1
  # define extra transpositions for different voices (e.g. +12, -24, ...)
  # note that the currently implemented method only gives good results with multiples of 12
  voice_transpositions = { VOICE1 : 0, VOICE2 : 0, VOICE3 : -12, VOICE4: -24, VOICE5: -12 }

Piece For Piano (with Violin)

Sailor's Hornpipe

Hoson zês, phainou, mêden holôs su lupou;
pros oligon esti to zên, to telos ho chronos apaitei.

[For as long as you live, be happy and do not be distressed in any way.  
Life exists for a short while, and Time demands its due.]

Ancient Greek text from the Epitaph of Seikilos, ca. 1st century C.E.

Seikilos

I've just written this, inspired, if that's the word, by wars that have broken out and are about to break out, with all the innocent human suffering and devastation they will bring.

My contribution to the Sound On Sound One Synth Challenge (https://soundcloud.com/one-synth-challenge/sets/one-synth-challenge-4)

The piece was created while self-isolating in Amsterdam, using the open source Yoshimi (http://yoshimi.sourceforge.net/) softsynth running on a Raspberry Pi 4 driven by an Arturia Keystep. More information on the backstory is here: https://www.soundonsound.com/forum/viewtopic.php?f=23&t=70769&start=210#p661810

Yoshimisynthesis

Yoshimi is a software synthesizer for Linux with long history and great sounds, based on ZynAddSubFX. Not long ago I discovered the WebAssembly port of Yoshimi by Jari Kleimola, and wanted to have a go integrating it into my own WebAssembly music studio. This is the result of the first attempt on creating a song:

Chill and feel

Hi,
I’m new so I can use every bit of feedback. 

Can you say something about this piece? What did you feel? What are your (dis)likes? What do you think is the idea behind this piece? Every bit of information helps!

Thank you
Have a great day!
Josef
