MIDI used to complete Beethoven's 10th symphony

MIDI Association contributor Walter Werzowa was featured on CNN today (Dec 26, 2021)

One of the best things about the MIDI Association is the great people we get to meet and associate with. After all they don't call it an association for nothing.  This year during May Is MIDI Month, we were putting together a panel on MIDI and music therapy and Executive Board member Kate Stone introduced us to Walter Werzowa. 

So we were pleasantly surprised today when one of Walter's latest projects was featured on Fareed Zakaria GPS show. 

As I'll detail on GPS in this week's Next Big Idea, musicologists, composers & computer scientists have used AI to complete Beethoven's unfinished 10th symphony.

The result of that work: https://t.co/omGX7VCfIn

HealthTunes®  

We first got interested in Walter because of Healthtunes.org. HealthTunes® is an audio streaming service designed to improve one's physical and mental health was founded by Walter in 2016. It uses Binural Beats.

Binaural beats and isochronic tones are embedded within our music (the low humming sound some may hear), which are two different methods used for brain wave entrainment. Binaural beats work by using two slightly different frequency tones sent to each ear. Isochronic tones use a single tone with a consistent beat being turned off and on regularly. Your body automatically reacts to both binaural beats and isochronic tones with a physiological response allowing one's brain to reach a more desired mental state by influencing brain wave activity.

musikvergnuegen- Audio Branding 

We soon learned that Walter had done many things in his career including memorable sonic branding themes from his company- musikvergnuegen. Vergnuegen could be translated as joy or fun and is used in the German word for amusement/theme park -vergnugungspark.  

Almost everyone on the planet has heard his audio branding signatures.  The Intel Boing and T mobile 5 note theme are all brilliant examples of simple mnemonics that could easily be described as ear worms.  

By the way, the term ear worm comes from the German  öhrwurm invented over 100 years ago to describe the experience of a song stuck in the brain.

Beethoven's "finally finalized" 10th Symphony 

But Walter's latest project is perhaps his most impressive yet. He was part of a team of AI researchers and musicians that used AI to "finish" Beethoven's Unfinished Symphony #10.  How was MIDI involved? Like most AI music projects,  the AI algorithm was trained using MIDI data of not only all of Beethoven's completed symphonies, but all of his other works as well as works from Beethoven's contemporaries that he would have listened to and been influenced by.  You can watch the NBC's Molly Hunter's interview with Walter or just listen to the results of Walter's work below.
