I only wrote the first 14 seconds of this (the part also occurring at 2:55). All the guitar parts (both melodies and rhythm) after that are generated with a deep neural network MuseNet by OpenAI, first in the style of Journey (0:14-2:55) and then in the style of The Beatles (from 3:09 to the end).
The Journey stuff is a compilation of several runs that I cut, copied and pasted to resemble something of a song (I downloaded about a dozen Journey chunks).
The Beatles parts are one continuous chunk written by the AI with a little human guidance (it always creates four options to select from before continuing to the next part).
So what I actually did was arrange the structure of the Journey parts (lots of duplicating the parts btw, MuseNet is somewhat clueless about song structure), added The Beatles parts, played them note for note on guitar and added bass and drums. So kind of a lot of human involvement still arrangement wise on this track. It's like producing a very chaotic artist.
I'm not familiar with either Journey or The Beatles, so if you are and can spot similarities to actual songs, it would be cool if you'd point them out. I really have no idea how close it gets to actual songs. The Beatles part is just crazy and leaves me wondering whether it's really that good or did it follow some specific song very closely. Even the tempo change in the outro is AIs work.
If you haven't already, you can try MuseNet here (works in a browser):
Click "show advanced settings" and for the intro select "custom (MIDI upload)" to upload your MIDI file.
Heres the MIDI for the intro I used:
Didn't know what to call the song so I used the Internet Anagram Server to find anagrams with the words "Journey" and "The Beatles" and "They Tore Bluejeans" came up. That's probably exactly how AI will remember us by. Although, "Shat by Neuro Jet Lee" would've been funnier I guess.
Anyway, any thoughts on our new overlords? Will we have a "write a song without using AI" challenge in 2050?
