Blob Opera is an experimental online music-making game developed by David Li in collaboration with Google's Arts and Culture team. It was released in December 2020 and quickly gained popularity.
In the game, the player controls four animated "blobs" that represent different vocal parts: bass, tenor, mezzo-soprano, and soprano. Each blob can be manipulated by the player to produce different pitches and sounds, allowing the player to create their own unique operatic compositions.
The game is based on machine learning technology that was trained on thousands of hours of real opera performances. This allows the blobs to produce a realistic and harmonious sound when combined, giving players the ability to create their own unique operatic performances.
The game has been praised for its accessibility and educational value, as it allows anyone to experiment with the fundamentals of vocal music-making in a fun and engaging way. The game has also been used in classrooms to teach students about music theory and vocal harmony.
Overall, Blob Opera is a fun and innovative game that showcases the potential of machine learning technology in creative applications.
