Where the Physics of Music and the Music of (Astro)Physics Collide
Inspired by the discovery of the remarkable TRAPPIST-1 planetary system, an astrophysicist, a musician, and an astrophysicist/musician decided to explore what happens when the rhythms and harmonies of astronomical systems are translated into music so they can be heard by human ears. The result is SYSTEM Sounds, a collection of music and animations generated by numerical simulations, real data, and a little creativity.
We recently developed a sound-based planetarium show Our Musical Universe with the support of the Dunlap Institute for Astronomy and Astrophysics and the IAU’s Office of Astronomy for Development. This is an audio and visual tour of the cosmos from the night sky all the way out to the edge of the observable universe and is accessible to the visually impaired.
We have developed a sound-based planetarium show Our Musical Universe which takes people on an audio and visual tour of the cosmos from the night sky all the way out to the edge of the observable universe. It is currently showing at the Dunlap Institute for Astronomy and Astrophysics’ planetarium at the University of Toronto. For tickets visit here. More dates will be added soon! The artwork features “Myth” by Robyn Rennie, who painted it after experiencing an advanced showing.
One of the world’s most adventurous musicians plays, and plays with, one the galaxy’s most enchanting planetary systems. Dan Tepfer uses a Yamaha Disklavier in conjunction with his own looping software to record and play back the pitches and rhythms of the TRAPPIST-1 planets. These notes result from bringing the planets’ actual orbital frequencies into the human hearing range. Dan then uses this planetary harmony to launch into his own improvised exploration.

The most famous star cluster in the night sky has released its first hip hop track. Recent measurements of the brightness variations of the Pleiades have shown that these stars pulsate in complex and harmonic ways. We have converted their light curves into sound waves to create an interstellar loop. The ghostly sound that sweeps through is a sonification of the image of the Pleiades and its dramatic reflection nebula. Click here for more information.
Want to learn more about the deep connection between music and astronomy and the stories behind some of our space music? Check out Matt’s talk at Hart House Orchestra’s performance of Holst’s The Planets or his longer talk at the Ontario Science Centre’s Saturn Star Party. For the latter, he’s joined by Andrew for a live performance of Saturn’s B Ring, for electric guitar and Rhodes.
The harmonic series forms the basis of musical harmony and rhythm and now you can hear it played by a hypothetical planetary system! Click here for more!
A new, fully narrated video that explains the marvellous music of TRAPPIST-1 and how it keeps the system from destroying itself.
