Ludwig van Beethoven was a famous composer who is well known for going deaf in the middle of his musical prime. Instead of forgoing his dream, he found other ways to experience the music, such as feeling the vibrations of his piano through the floor. The Beethoven app is similar, in that it offers another way to sense and communicate music. For those who cannot write sheet music, but wish to show their creativity to the world, or for the average person who wants to transcribe the audio of their favorite piece into a sheet that they can play, this web app is the perfect creation. The Beethoven app boasts the ability to filter through background noise to find piano frequencies, and can work with single notes at very fast speeds.
