Disquiet Junto Project 0712: Zebra Code
The Assignment: What rhythm do you hear in a bar code?

Step 1: Locate something you purchased or received that has a zebra code, or bar code, on the packaging.

Step 2: Interpret the bar code from Step 1 as a rhythm.

Step 3: Make music using the rhythm from Step 2.

This project was proposed thanks to Jason Richardson (aka Bassling), who shared this Boing Boing post:

Disquiet Junto Project 0712: Zebra Code

Disquiet Junto 0712 invited us to interpret a barcode as a rhythm.

The first barcode patent was issued in 1952, but they didn't look like the ones we usually see now: they were bullseye-shaped. Today's linear barcodes use what is called "many-width symbology", meaning that the vertical lines ("modules") in the barcode are different widths, from 1 to 4. The lines are printed vertically instead of horizontally so that if the ink smeared during printing, the code would still be legible and no information would be lost. 

Barcodes almost failed in the retail space, because no one wanted to be the first to invest the money to adopt them when they were unproven. They were a lot  more popular more quickly in the railroad business, where by the early 1960s optical scanners could read the color-coded barcodes on train cars as they rolled past at full speed.

The barcode I chose as source material for the prompt was from a tape dispenser that I bought to help my daughter pack to leave home. This piece is probably an aural photograph of the feelings I'm having right now, but that's neither here nor there. Where was I?

Instead of reading the barcode as if it were visually measuring out beats, I decided to decode the modules and transcribe the widths. This turned into the sequence 2 1 3 2 1 4 4 1 / 2 1 2 3 1 1 1 3 / 3 1 1 1 3 1 1 1 / 1 1, which I incorporated into this piece in several ways.

First, the percussion pattern is built by breaking the sequence into chunks of four numbers. These four numbers indicate the beat position of a series of drum kit components on a 16-step grid. So 2-1-3-2, the first sequence, means the kick drum hits on the 2nd, 1st, 3rd, and 2nd beats of the four divisions of the pattern. Next would be the snare, then the tom, and finally the hihat with 1-1-1-3. The sequence also determines the note length and note number of the "melodic" sequence. 

Finally, I translated the sequence into steps in a custom arpeggiator, with the width of the modules transposed into the vertical axis of the beats in the pattern. There are two arpeggiated synth tracks, running at different rates, played on the Logic ES2 and Alchemy software synths. A triggered vocal sample rhythmically reflects the numeric sequence. The rest of the synth parts came from the Roland boutique Studio Electronics SE-02, a reissue of the "Moog-adjacent" SE-01 analog monosynth of 1982.

There's a lot going on in this piece, but there's a lot going on over here, too. The sound that a single mom makes in her empty nest. Snapshot of a moment in time at 90bpm.
