Blob Opera is a playful music game created by David Li with Google Arts & Culture. It uses machine learning to simulate real operatic voices, letting players compose music without any musical training. You control four colorful blobs, each representing a different vocal range (soprano, tenor, mezzo-soprano, bass). Move them up and down to change pitch, or side to side to adjust vowel sounds. The game responds in real time, making it easy to experiment with harmonies and melodies. Once you’ve created something you like, you can record and share your performance. There’s even a festive theme toggle for seasonal fun. Perfect for casual play or creative experimentation, Blob Opera turns opera into an interactive, lighthearted experience. Try it out—no singing skills required.
