Black Midi is also the name of a rather excellent band: https://bmblackmidi.com/

Their naming is quite inspirational. If I ever start a popular band I will also try to make some existing thing completely un-googleable. The band Franz Ferdinand also tried this and seem to have failed.

My favorite little band naming micro-trend was bands naming themselves after Python projects, but doubled. Eg, there are bands named "Django Django" and "PyPy".

A sample, very popular composition for anyone who is interested in giving the genre a listen: https://m.youtube.com/watch?v=Ay8vzCHkgEk

Here‘s another one from Queen, to give an impression of a more popular song: https://m.youtube.com/watch?v=HjwzR3BqMZ4

These are great. They must be abusing note velocity for the "art" sections, right? The melodic parts are obviously being played much more loudly (velocity in MIDI terms) than the beautiful tapestry-like backgrounds. Although I realise a lot of the crazy stuff is also a valid part of the composition (the big blocks of notes emulating drum beats etc).

Some (most?) of the black midi scores do cheat a bit. They have bajillions of notes but most of the notes are not audible. Their presence gives cool visual effects (either static if you decide to print it out as classic music notation or dynamic when an app plays the tune) and that's it. Edit: they typically still have enough audible notes to make it sound like a dozen clones of Chopin played together.

> They have bajillions of notes but most of the notes are not audible

Good point; and if they would be audible the latency would have been unbearable, since the MIDI 1.x protocol only supports ~31kbit/s; each note requires 3 bytes for on an off each; so e.g. a chord with more than ~20 notes no longer sounds like a chord, but like an arpeggio; many expanders I had were even slower.

Earlier quoted context omitted.

It doesn't seem ungoogleable to me: if you google "black midi" all you find is that band.

You've misinterpreted the comment, this is exactly what they mean. The recent band, has made the term ungoogleable.

Yep, I don't keep up with new music that much anymore but when I saw the title of this post, my mind immediately went to these lads. Perhaps they thought that naming themselves after the genre would prompt more people to discover it but it backfired?

The article says they sometimes play them slowly and speed the recording up to the correct speed afterwards.

I don't believe black midi can be played on normal instruments, it's mostly computer-based (barring the punchcard pianos). In fact even standard pre-black-midi software would probably crash when trying to open such files.

This would hit physical limits with MIDI 1.x, since you would then have to somehow transpose down the music (to correct for the transpose up because of the much faster playback speed) which would cause a greatly reduced quality (or not work at all) since the frequency range by MIDI expanders and audio equipment was less than 20kHz. And the auditory masikng caused by the ear sets yet another limit.

More history: https://bedrocksolidmc.wixsite.com/blackmidi/history

According to that article, this should be the first Black MIDI composition (also mentioned in the Wikipedia article): https://youtu.be/6P9ISmtWUKI

I also enjoy this newer version: https://youtu.be/GCIPZrwOBSU?t=35

Both of them never fail to get a visceral reaction out of me...

Tau ("the Song with 6.28318 Million Notes") is an extreme example : https://www.youtube.com/watch?v=b0gyQMJHQ78

I like the "no arts" version that removes silent notes, as it makes it more enjoyable (for me!) to follow what's happening : https://www.youtube.com/watch?v=VcfmPZVqVtw

However, one other interesting aspect of a song like Tau is the "performance" of playing these note-heavy midis. You are effectively recording a live performance of your computer processing/performing the midi file, it is not like playing a recording.

This implies that for a good portion of black midi history, it was not possible for most computers to play those files without screen freezes, heavy skipping notes, and then recovering after the hard portion has passed.

It was/is necessary to overclock CPUs to avoid or minimize these artifacts on songs like Tau.

And it can be said that screen freezes/note skips are integral parts of the performance. At least that's my take and I really do enjoy seeing the computer almost giving up to then recover and finish the song.
