On subsequent listens, my ears learn to decompose the sound into parts (melodies, harmonies, voices), and to track the progress of those parts individually over time. The first time I hear a piece of classical music, I’m often overwhelmed by the complexity- there are so many instruments at play, and there is limited repetition. I have a few ideas about why these animations are so popular. Jason Forrest recently wrote about this “MIDI Sequencer” approach. Read about how it’s made - MATLAB, Excel, Adobe Premiere…įeatured in Edward Tufte’s seminars, Stephen has explored tens of rendering techniques for animating musical notes since 1985. When I think of classic “piano roll” style animations, I think of Stephen Malinowski’s work. This is a small collection of resources for progammatic live music visualization. Working with raw sound files will lead makers down the path of learning digital signal processing. Additionally, music data comes in many forms (discrete notes, or continuous sound waves). Humans are sensitive to lags of as little as 2 ms, and have reduced task performance with lag of as little as 50 ms ( source).

People feel that something is “off” when TV broadcasts are out-of-sync with the audio. In contrast, synchronizing sound to visuals requires very short delays to be convincing. Few data applications outside of high frequency trading or cyber-physical systems have sub-second latency requirements. While viewers will have their attention split between auditory and visual channels, compelling visualizations achieve synergy where noticing something interesting in one channel corresponds with interesting output in the other.ĭespite not being used for direct problem-solving, music visualization producers still face technical challenges. They may help in ways hard to explain in words, but easily understood when experienced. Without the right balance of structure and unpredictability, musical data graphics can be forgettable noise.Įffective music visuals enhance listening experiences by making the beauty of sound structures visually salient. However, there is still a gradient of effectiveness for the task of “visually describing something that is not visual” (Jason Forrest), whether for artistic or other goals. Unlike many other families of data graphics, music visualizations are rarely burdened with the responsibility of solving numerically oriented problems. You can see the data but you will not hear the music. Looking at tables of any substantial size is a little like looking at the grooves of a record with a magnifying glass.
