Computer Generated Music Presentation by Alex Whetham
Focus This presentation will be more focused on … ● Early examples of computer generated music ● Keygen Music ● Computer Generated Midi Music + for Human Performance ● Modern Technology Generating Music without Midis or Midi Composing
So … What is Computer Generated Music? ● There are many types of definitions for Computer Generated Music, spanning a wide variety of music fields ● But the simplest definition? ● Using computer technology to aid in the creation of music, whether it be in composition, sound design, or sound synthesis
Earliest Example of Computer Generated Music ● 1951 - Alan Turing ● Alan Turing - the man famous for breaking the Nazi’s enigma code during WWII, the 2015 film the Imitation Game starring Benedict Cumberbatch was about him. ● He was a mathematician, but he also built a giant computer capable of outputting notes with human programming.
Alan Turing’s Computer Generated Music ● Less focused on making a tune, more just around notes, made during an all night programming session ● In 2016, the recording was restored: ● https://soundcloud.com/guardianaustralia/first-ever-recording-of-computer- music The guys who restored it
Now let’s jump forward to the 90s...
Well, What is Keygen Music? ● To start, Keygen is software that develops a licensing key for a program ● During the 90s, this was used legally and illegally to generate keys and licenses for a variety of programs ● Focusing on illegal side, there were teams of hackers who would generate keys by “cracking” into the code of the programs they would generate keys for ● These teams would often try to outdo each other in many ways and create some healthy competition
Keygen Music ● One of the ways these teams of “hackers” would compete would be to use the software and their programming knowledge to create crazy intros and use the computers cards and ocassionaly the programs themselvesto create music and visuals ● These would play whenever you generated a key ● An example of the music: https://www.youtube.com/watch?time_continue=94&v=rFv7mHTf0nA
However... Keygen was music made by What about music made by humans with a little help from computers with just a little help from computers... humans?
Computer Generated MIDI Music ● MIDI - Musical Instrument Digital Interface ● Summing up simply is hard, but basically it is how musical interfaces in electronic and computer interfaces speak to each other ● How a keyboard you plug into your computer can play notes on programs that make music
How Does Something Like This Work? ● Very complex to make computer generated midis, but … ● Computer Programmers program an algorithm, that a computer reads when you run the program and based on what computer has been programmed to do, outputs a midi file that the computer will attempt to read as music. ● Example: Computoser ● This stuff is not composed by a human, but it still needs a human’s help to tell it what kind of music to play
Computers Composing Music for Humans ● There have been a couple versions of computers that have been created to compose music but not output it itself. ● May sound more primitive, but the example here: Iamus, can create full classical symphonies in 8 minutes ● Humans then would play the symphony based on what Iamus has written A Symphony by Iamus
Midi-less Computer Generated Music ● Dadabots ● Taking music that doesn’t necessarily rely on notes, but more on atmosphere and mood ● Math Rock, Black Metal, etc. ● I’m not too familiar with either of these genres, so here’s an example to get us all into what Dadabots has made: ● Math Rock: Battles - Atlas ● Black Metal: Kralice - Diotima
DadaBots’ Versions of What We Heard ● They programmed their computers that they made to “listen” to the songs that I played for you for a certain amount of time and output their version of the song ● This is not dissimilar to the Google Deepdream picture algorithms ● Dadabots - Black Metal ● Dadabots - Math Rock ● Pretty strange stuff … ● … but it seems to retain the atmosphere ● And better than simple midi instruments
Who knows where the future of computer generated music and computer music can go?
