Watched a great lecture on the relationships between rhythm, pitch and color given by Adam Neely at Abelton’s Loop 2017 conference. It gets “out there” at times, but he pulls it all together as he demonstrates how everything is essentially rhythm.
Particularly liked this “The Color of Sound” chart from Nicolas Melendez and Clint Goss that Adam referenced. It shows the direct correlations of pitch and light frequencies. It would be cool to use this when putting together a concert’s light show!
