An interactive history of computerized music
The Machine Sings
Hear how musical ideas became instructions, synthesized sound, and portable data.
Before a computer could make a sound
“The engine might compose elaborate and scientific pieces of music of any degree of complexity or extent.”
— Ada Lovelace, Note G (1843)
Lovelace recognized that a general-purpose machine could manipulate symbols beyond arithmetic. Her Bernoulli-number program was not a musical composition, but it gives us a practical way to hear the central idea: a rule can become a sequence, and a sequence can control sound.
1843 to today
A short history in signals
- SymbolsLovelace describes how an analytical engine could act on musical relationships.
- Audible computationCSIRAC played programmed tones, while a Manchester computer produced the earliest surviving recording of computer-generated music.
- Composition and synthesisThe Illiac Suite used rules to compose for strings; Max Mathews’s MUSIC produced digital sound at Bell Labs.
- A computer singsAn IBM 704 performance of “Daisy Bell” became a landmark in computer-synthesized singing.
- New timbresJohn Chowning published a practical method for creating complex spectra with frequency modulation.
- Instruments communicateMIDI standardized musical events such as pitch, timing, and velocity across devices.
- Systems collaborateRule-based, probabilistic, and learned systems now support composition, performance, and production.
Three practical labs
Listen to the ideas change
1843 · Symbolic instructions
Map a mathematical sequence into music
Change the rule’s interpretation, then compare the numbers with the notes they produce.
1957–1961 · Digital synthesis
Build a sound from an oscillator
Early synthesis software described sound numerically. Compare simple wave shapes, then hear a browser-rendered melody from “Daisy Bell.” This is an illustration, not a reconstruction of the IBM 704 voice system.
The 1961 demonstration by John Kelly and Carol Lockbaum, using work led by Max Mathews at Bell Labs, was a landmark in computer-synthesized singing.
1983–today · Musical events
Inspect notes as portable data
MIDI describes performance instructions rather than recorded sound. A seeded rule below generates the same event list every time.
