Beau Sievers

I'm a PhD student in Cognitive Neuroscience at the Dartmouth Social Intelligence Lab with Professor Thalia Wheatley. My research has focused on how we understand emotion in music, movement, and other sensory modalities.

I am also a composer. I help organize Indexical with Andrew C. Smith and David Kant.

Bouncing Ball

Bouncing Ball is open source software for comparing the dynamics of music and movement as described in Sievers, B, Polansky, L, Casey, M, & Wheatley, T (2013). Music and movement share a dynamic structure that supports universal expressions of emotion. Proceedings of the National Academy of Sciences, 110(1), 70-75.

Morphological Metrics

Morphological Metrics is a Ruby implementation of metrics described in Larry Polansky's article Morphological Metrics. Larry's work on Morphological Metrics is of interest for anybody who wants to quantitatively compare contours; I came to it as a composer and continue to return regularly as a scientist.

Ruby PCSet

Ruby PCSet is a simple Ruby library for performing musical pitch-class set theory operations. It has a few nice things which similar tools lack, including evaluation of some properties described by Balzano (coherence, uniqueness) and Huron (aggregate dyadic consonance).

My master's thesis, containing research which became the basis of Sievers et al. (2013): Follow the Bouncing Ball: Music, Motion, and Emotion.

Sometimes I am a mixing and mastering engineer. I've worked on Larry Polansky's album The Theory of Impossible Melody, Kui Dong's album Since When Has the Bright Moon Existed?, and an album by Brendan Landis called Slow Names.

I have made some art. Every Tour of Elysian Park, volumes 1 and 2 was a project for the Elysian Park Museum of Art. I wrote a computer program to combinatorially generate every possible tour of Elysian park, and printed out the first 10,000 possible tours. The printouts were exhibited at the LACE gallery in Los Angeles, California. Recording boxes for Mondrian and Travel recording with contact microphones: from Brooklyn to Den Haag were two collaborations with Joanne Cheung exhibited in Carry-On, a David Horvitz show at Galerie West in Den Haag, then at Maison populaire near Paris, then again at Galerie West in Den Haag.

As an undergraduate in the Music Synthesis department at the Berklee College of Music, I wrote a introductory guide to sound synthesis with examples in PureData: A Young Person's Guide to the Principles of Music Synthesis.

Around the same time, I built Metropolis, a polyrhythmic metronome built with Max/MSP. You can download it here: Download OS X application. Download Max/MSP patch. Watch screencast.

In 2005 I was commissioned by Cambodian Living Arts to produce and engineer Khmer Passages, an album of traditional Khmer music, along with Yun Theara and 2004-05 Rufus Choate Scholar Parker Barnes.

While working with Studio CLA in Phnom Penh in 2003-04, Parker Barnes, Eli CP, Ben Lerer, myself, Yun Theara, Savy Ouch, and numerous other talented Khmer musicians recorded an album. Here's a San Francisco Chronicle Magazine article about the project. And here's the All About Jazz review.

I play drums with Pineapple Island Tribesmen. When I lived in Boston, I also played with ...and people and crocodiles...
