BitCrush^♪25

Northwestern’s music tech hackathon {♪}

Nov 15, 4-7pm

Annenberg Hall

Evanston Campus

Prizes—food—music—more!

What is BitCrush?

The BitCrush music tech competition is a first-of-its-kind event for college students. Teams of 1-4 students will create and perform short musical compositions for a panel of judges and a live audience. Performances can include instruments, vocals, and dance along with live computer coding to generate music. All teams will have access to experts from Northwestern University who can work with you to develop performances. You can think of it as a kind of hackathon for music with live performances.

How do I get started?

Form a team of 1-4 people. The competition is open to all students.
Fill out the registration form.
Check out our getting started music coding tutorial.
Start thinking about the genre and structure of your performance. Will you include live instruments, vocals, or dance?

When and where is the competition?

The competition will be on Saturday, November 15, 2025 on the Evanston campus in Annenberg Hall. Setup will start at 3pm and the competition will run until 7pm.

Who can be in the competition?

The competition is open to all current college students. Undergraduate, graduate, and associate-level students are welcome.

What if I need help with my performance?

We will hold regular drop-in support hours open to any team in the competition. Just email bitcrushlive@gmail.com to set up a time.

Who runs the competition?

BitCrush is run by the TIDAL Lab at Northwestern University and is sponsored by the Northwestern Network for Collaborative Intelligence and the Center for Responsible Technology, Policy, and Public Dialogue. The event also has funding from the National Science Foundation.

How will teams be judged?

Teams will be judged based on five factors: entertainment, musicality, creativity, technical ability, and live coding. We will post a scoring guideline here soon.

Why should I be in the competition?

It’s fun. And, there will be trophies for the winning teams. It’s also part of a free event with food, prizes, and live music.

What do you mean by live-coded music?

Live coding means that you write computer code in a language like Python to generate music. You can combine code with pre-recorded samples, live instruments, vocals, dance, costumes, special effects, and more. You can use any music+coding platform for your performance. Popular options include Strudel, EarSketch, Sonic Pi, TunePad, Max, ChucK, and SuperCollider.

I still don’t understand what live-coded music means…

Where can I learn more about live coding?

Here are some learning resources to get started with live coding on different platforms.

Live Coding Example

You can also try live coding yourself! Just press play on the python code cells below.

kick = 0 snare = 2 for _ in range(2): playNote(kick, 0.75, velocity = 70) playNote(snare, beats = 0.25, velocity = 50) playNote(kick, beats = 0.5, velocity = 70) playNote(snare, beats = 0.5, velocity = 50) / /

hat = 4 # press PLAY and then uncomment these lines to add in hi-hats #for i in range(8): playNote(hat, beats = 0.25) #for i in range(2): playNote(hat, beats = 0.5) #for i in range(8): playNote(hat, beats = 0.25 / 2, pitch = i/4) / /

from random import randint clap = 10 # uncomment these lines to add in random claps ''' for i in range(64): if randint(0, 10) > 7: playNote(clap, beats = 0.25) else: rest(0.25) '''

chord1 = [ 48, 52, 55, 59 ] chord2 = [ 52, 55, 60, 62 ] chord3 = [ 50, 55, 59 ] chord4 = [ 50, 53, 57, 59 ] playNote(chord1, beats = 4) playNote(chord2, beats = 4) playNote(chord3, beats = 4) playNote(chord4, beats = 4)

chord1 = [ 48, 52, 55, 59 ] chord2 = [ 52, 55, 60, 62 ] chord3 = [ 50, 55, 59, 62 ] chord4 = [ 50, 53, 57, 59 ] for note in chord1 * 4: playNote(note - 12, beats = 0.25, velocity = 60) for note in chord2 * 4: playNote(note - 12, beats = 0.25, velocity = 60) for note in chord3 * 4: playNote(note - 12, beats = 0.25, velocity = 60) for note in chord4 * 4: playNote(note - 12, beats = 0.25, velocity = 60)
