Music is embedded with mathematical logic -- But it can be hard to hear the patterns beneath the sounds.
Which is where visualizations come in. While bar graphs call to mind business presentations and third grade science fair projects, YouTube user musanim has repurposed these little lines to help you out.
Using Music Animation Machine MIDI Player, classical favorites including Ludwig van Beethoven's Fifth Symphony, Claude Debussy's Clair de Lune and more, appear as colored lines that scroll along as the music plays. Lines are different lengths depending on the time they're held in the song, and different colors depending on the note being played.
Other kinds of visualizations -- like this interval graphic used in one of Chopin's nocturnes -- also appear on musanim's page.
