This is the frequency fingerprint of all 4 movements of Beethoven's 9th Symphony. For each movement, the frequencies of the notes played are tallied (weighted by the length they each note is held) and then all notes are played simultaneously, with the more frequently played notes louder. This creates an identifiable sonic fingerprint of the work that in some sense sums up the entire movement. Frequency Fingerprints can be created from MIDI files with this tool: https://www.kaggle.com/code/bre
