New musical instruments

A presentation for Berklee BTOT 2015 http://www.berklee.edu/faculty

Around the year 1700, several startup ventures developed prototypes of machines with thousands of moving parts. After 30 years of engineering, competition, and refinement, the result was a device remarkably similar to the modern piano.

What are the musical instruments of the future being designed right now?

  • new composition tools,
  • reactive music,
  • connecting things,
  • sensors,
  • voices, 
  • brains

Notes:

predictions?

Ray Kurzweil’s future predictions on a timeline: http://imgur.com/quKXllo (The Singularity will happen in 2045)

In 1965 researcher Herbert Simon said: “Machines will be capable, within twenty years, of doing any work a man can do”. Marvin Minsky added his own prediction: “Within a generation … the problem of creating ‘artificial intelligence’ will substantially be solved.” https://forums.opensuse.org/showthread.php/390217-Will-computers-or-machines-ever-become-self-aware-or-evolve/page2

Patterns

Are there patterns in the ways that artists adapt technology?

For example, the Hammond organ borrowed ideas developed for radios. Recorded music is produced with computers that were originally as business machines.

Instead of looking forward to predict future music, lets look backwards to ask,”What technology needs to happen to make musical instruments possible?” The piano relies upon a single-escapement (1710) and later a double-escapement (1821). Real time pitch shifting depends on Fourier transforms (1822) and fast computers (~1980).

Artists often find new (unintended) uses for tools. Like the printing press.

New pianos

The piano is still in development. In December 2014, Eren Başbuğ composed and performed music on the Roli Seaboard – a piano keyboard made of 3 dimensional sensing foam:

Here is Keith McMillen’s QuNexus keyboard (with Polyphonic aftertouch):

Experiments

Here are tools that might lead to new ways of making music. They won’t replace old ways. Singing has outlasted every other kind of music.

These ideas represent a combination of engineering and art. Engineers need artists. Artists need engineers. Interesting things happen at the confluence of streams.

Analysis, re-synthesis, transformation

Computers can analyze the audio spectrum in real time. Sounds can be transformed and re-synthesized with near zero latency.

SMS-tools

by Xavier Serra and UPF

Harmonic Model Plus Residual (HPR) – Build a spectrogram using STFT, then identify where there is strong correlation to a tonal harmonic structure (music). This is the harmonic model of the sound. Subtract it from the original spectrogram to get the residual (noise).

Settings for above example:

  • Window size: 1800 (SR / f0 * lobeWidth) 44100 / 200 * 8 = 1764
  • FFT size: 2048
  • Mag threshold: -90
  • Max harmonics: 30
  • f0 min: 150
  • f0 max: 200
Many kinds of features
  • Low level features: harmonicity, amplitude, fundamental frequency
  • high level features: mood, genre, danceability

Can you jam over the internet?

What is the speed of electricity? 70-80 ms is the best round trip latency (via fiber) from the U.S. east to west coast. If you were jamming over the internet with someone on the opposite coast it might be like being 100 ft away from them in a field. (sound travels 1100 feet/second in air).

“Robots and AI will help us create more jobs for humans — if we want them. And one of those jobs for us will be to keep inventing new jobs for the AIs and robots to take from us. We think of a new job we want, we do it for a while, then we teach robots how to do it. Then we make up something else.”

“…We invented machines to take x-rays, then we invented x-ray diagnostic technicians which farmers 200 years ago would have not believed could be a job, and now we are giving those jobs to robot AIs.”
