[album] PLATO Computer Music 1977-1982 by Bill Schaeffer

Here's some of the best chipmusic from before chipmusic was even invented.


This music was made on a Gooch Cybernetic Synthesizer at the experimental music lab of the University of Illinois. The GCS was one of the first wavetable synths ever made. It generated sound from looped 256 step waveforms, and was programmed through a PLATO computer terminal.

The CD is available from CDbaby, if you're interested.

Computer Music in 1949?

Some time ago, it was revealed here on Ancient Wonderworld that CSIRAC was not the first machine to play computer music, and that actually Frances E. "Betty" Holberton programmed the UNIVAC I to perform music to the public a couple of months prior to the Sidney events in 1951.

Ever since, I have been wondering if there are perhaps even earlier examples of computer music. There are some claims that US Air Force Lt. Herb Finney wrote a music routine for the UNIVAC I serial #2 before B. Holberton did hers for the #1. Unfortunately, I have not been able to find any substatial information backing up these claims. Furthermore, considering that the performance by B. Holberton might have been already in March 1951 rather than June as previously assumed, we cannot be sure who was first based on the currently known facts.

Then some time ago I stumbled across this odd CYHIST newsgroup message from 1997, wherein a certain Kathryn Kleiman claims that Betty Holberton told her that

"[...] in the spring of 1948, on the eve of the introduction of the BINAC, a party for all the employees of Eckert-Mauchly Computer Corporation was thrown. As a highlight of this party, she programmed BINAC to play "For He's A Jolly Good Fellow" for all the employees who had worked so hard to get the machine out the door. The performance was quite a hit!"

Now that would be quite amazing. Especially considering that the BINAC only ran it's first test program on February 7th, 1949, and certainly wasn't operational in 1948. So until now I had good reason to believe that K. Kleiman's claims are incorrect, and that she got confused with the events surrounding the UNIVAC I. There is evidence that Louis D. Wilson installed a diagnostic speaker on the BINAC; but that's about it.


The BINAC

Or so I though. Until I came across this fascinating oral history interview with Jean J. Bartik and Betty Holberton, conducted by Henry Tropp in April 1973. On to page 169:

BARTIK: Well, we had it singing songs and stuff and playing music.

HOLBERTON: Well, that was done at the demonstration because that I did the night before the demonstration, and I don't remember when —

BARTIK: And when was the demonstration?

HOLBERTON: When was the demonstration in relation to shipment?

TROPP: That would have been fairly late

HOLBERTON: Fairly late.

TROPP: in '49.

HOLBERTON: It would have been in the spring. Yes.

Based on this, it is safe to say the above statement by K. Kleiman is indeed true, save for the year. I have not been able to pinpoint the date with certainty, most likely they are talking about the official verification test, which took place on April 7th, 1949.

Betty Holberton at the ENIAC

In any case, there you have it: The world's first computer music was made as early as 1949. So next time you write something about Betty Holberton (then still known as Betty Snyder), don't just mention her pioneering programming work on the ENIAC, the writing of the first computer manual, the development of the C-10 and COBOL programming languages, or the design of the UNIVAC console. Also mention that she invented computer music.

Sadly, no recordings were made of that historic achievement. Perhaps the papers by Betty Holberton contain some information about the inner workings of the music routine at least, so if anybody happens to stop by the Charles Babbage Institute in Minneapolis, I urge you to take a look at them and let me know about any possible findings.

Also, if you do have any other stories about early computer music, please do share them in the comments below.

[album] Tartare de Biscotte by Thiaz Itch

A new Thiaz Itch album, horray! No, it's not chip. But it's awesome, and more importantly, it's absolutely nuts. So I urge you to check it out anyway.

[demo] Abre los ojos by oobc

This gotta be one of the craziest demos I've seen this year. First of all, the platform: CBM 8032 aka Commodore PET! If that alone isn't crazy enough, the demo itself is rather... different. It starts out with something which sort of resembles a twister, but then takes a rather unexpected turn. I don't want to spoil it too much, so let me just say that I have rarely ever seen something so unique and sinister. An absolute masterpiece in my opinion, and well-deserved first place in the Wild compo at Zoo this weekend.

Though right now my favourite track from the compo is "hexamerica" by Pulselooper.

Update: Now also available on bandcamp in a slightly remastered edition.

1-Bit Forum Competition 2015

As I mentioned earlier, the 1-Bit Music Forum just recently re-opened after a complete database loss. To get things rolling again, we've now launched a big fat music competition with contests on various platforms, a category for tiny (1KB) tunes, as well as an opportunity to show off your coding skills.

The compo will run till September 1st and is open to everyone, although only registered members of the 1-Bit Forum may vote.

Read up on the full details and join the party here.

[demo] Travel by Resistance

Sorry for the silence folks... real life was getting a bit in the way recently, but I hope to make up for it in the coming days.

So, today we have a neat Sega Megadrive/Genesis demo by Amiga veterans Resistance. Actually not so veteran at all, as this is not only the groups' first Megadrive dempo, but supposedly it's also Nainains' first forray into coding.

Not that many effects to see here, but the graphics and music are slick, and on top of that, some fresh Sega stuff is always highly welcome of course. The demo came in 3rd at Solkogens' oldskool compo, by the way.

Rekengeluiden van PASCAL - The Oldest Dutch Computer Music Recording

(c) Philips 1962
On my quest of documenting the beginnings of computer music history, I've come across another gem from the early days. Here's the story behind this amazing time capsule in audio form, whose significance has been largely overlooked so far.

We are writing the year 1960. After a somewhat sluggish start the computer revolution is getting into full swing in the Netherlands. At the Natuurkundig Laboratorium in Eindhoven, Philips just completed their second computer, the Philips Akelig Snelle Calculator (Philips Frighteningly Fast Calculator), or short PASCAL.

The head of the NatLab at the time, a certain W. Nijenhuis, had the idea of installing a small amplifier and loudspeaker on the PASCAL, which would pick up radio frequency interference generated by the machine. Unsurprisingly, the usual course of events unfolds: While actually intended for diagnostic purposes, people quickly discovered that they could abuse the speaker to make simple music. But Mr Nijenhuis, rather than scolding his staff for the waste of precious calculation time, actually decides to record those rekengeluiden (computing noises) on a 45 rpm vinyl.

Thus, "Rekengeluiden van PASCAL" was born. Side A of the record contains recordings of the computer during regular operation, including some of the mechanical noises the machine would make. Likewise, the first track on the B-side is a recording of a prime number calculation. Listening to these recordings may already give us an idea of how the whole radio frequency interference music business came about: These algorithms don't just produce random bleeps and bops, they actually sound quite beautiful themselves, and are remniscent of some modern day bytebeat compositions.

Track number two on the B-side is a nice rendition of a Mozart minuet. But Nijenhuis doesn't stop there. The last track on the B-side, "Stochastische melodie", takes things one step further - it's not just performed by the computer, but the machine also composed it.

The record was distributed as bonus material with Philips' in-house magazine, the "Technisch Tijdschrift" in Spring 1962. Chances of finding a copy nowadays are probably close to zilch, but fortunately a kind soul has uploaded an mp3 version. So, I hope you'll all enjoy this one-of-a-kind piece of computer history!

CSIRAC Was Not The First: Rewriting Computer Music History Once Again

For many years it was believed that the first experiments in computer music were done by Max Mathews at Bell Labs in 1957. In the early 2000s however, a research team concerned with the history of the CSIRAC mainframe at the University of Sidney, Australia found documents confirming a musical performance by that machine on August 7th-9th, 1951. Also, in 2008 the BBC unveiled a hidden gem from their archives: A computer music recording from autumn of 1951, done by Christopher Strachey on the Ferranti Mark I at the University of Manchester just a few weeks after the Sidney performance.

In fact, Geoff Hill's 1951 experiments have held the status of the first computer music in history ever since. However, according to my most recent research, it's time to change the record once again.

The UNIVAC I control panel, designed in part by Betty Holberton

In May 1990, the Charles Babbage Institute, the Smithsonian Institution, and
the Unisys Corporation brought together many of the pioneers and masterminds behind the UNIVAC I computer for a commemoratory Univac Conference. During the main panel, the attention suddenly turns to the little lpudspeaker that was installed on the machine for diagnostic purposes. Louis D. Wilson recalls:

When we were testing BINAC out, we were working two shifts and we worked all night long, and we had a radio going. After a while we noticed that you could recognize the pattern of what was happening at the moment by listening to the static on the radio. So I installed a detector in the console and an amplifier and a speaker so that you could deliberately listen to these things.
At this point, Frances E. "Betty" Holberton starts to wonder:
Does anybody know who actually wrote the first generator for the UNIVAC or for any computer that played music? [...] Herb Finney?
Morgan W. Huff responds:
Herb Finney, Air Force. Office of the Air Comptroller.
Hmm, interesting, but that doesn't really help us, since nobody puts a date on it. What does help us however is the conversation between Wilson and Holberton that now follows:
WILSON: Well, if you remember it, the dedication party, when we got the first machine running, John Mauchly programmed...

HOLBERTON: No, I programmed that.


WILSON: Oh, did you do that?


HOLBERTON: I certainly did. It was supposed to have been a surprise, and we did it at 2 o'clock in the morning. There were some engineers working on the BINAC and they heard it. It was actually an interpretive routine. It only had eight notes and it played "For he's a jolly good fellow," or something like that. But it was supposed to have been a surprise and it wasn't.
That "dedication party" Wilson mentions can indeed be dated. It's the dedication event of the completion of the first successful UNIVAC I installation for the US Census Bureau, which took place on June 14th, 1951.

Frances E. "Betty" Holberton


In fact computer music history might go back as far as the early days of the BINAC computer, but unfortunately we may never know. Betty Holberton is not around to tell her story anymore, she passed away in 2001; and I have yet to find more information about Louis Wilson or the mysterious Herb Finney. So, for the time being, the date of June 14th, 1951, may stand as the first ever public demonstration of computer music.

All quotes in this article are taken from the transcript of the 1990 Univac Conference at the Smithsonian Institution in Washington, DC, pages 72-73. The transcript as well as the original audio recordings can be found here.

[album] Corrosão Seletiva by Pulselooper

Gotta take a break from all these mindblowing demos. Instead, I'm gonna promote this excellent new Gameboy release, by no other than the mighty Pulselooper. He's back, and he's pissed! From the release notes:
Over the past decade, a new Middle Class has emerged in Brazil. Very partly due to government aid that since 2002 had as its main point the extinction of extreme poverty, leveraging classes C to B and B to A. This new Middle Class, abnormally, took for itself a point of view of hatred and rancor to the same popular programs that, in a way, helped create their new status. And they recently went to the streets, asking for demands like the obligatory prison of young people under 18 years, dreading an absurd so-called "communist government in Brazil" and also supporting the back of the military dictatorship from the 60s and 70s. This album is a tribute to them.
