Can AI Make You an Opera Star?

What if you could compose and perform a four-part opera without any musical training? 

Here's a Cool Tip: Blob Opera!

Google's Blob Opera, an AI experiment by artist David Li in collaboration with Google Arts & Culture, makes this possible. 

This interactive tool allows users to create harmonious operatic music by manipulating colorful, animated blobs—no prior musical knowledge required.

What Is Blob Opera?

Blob Opera is a machine learning experiment that enables users to create operatic music through an intuitive interface. 

Each of the four blobs represents a different vocal range: bass, tenor, mezzo-soprano, and soprano. By dragging the blobs up and down, users can change pitch; moving them forward and backward alters vowel sounds. 

The AI harmonizes these inputs in real-time, producing rich, operatic performances.

The underlying AI was trained on 16 hours of recordings from professional opera singers: Christian Joel (tenor), Frederick Tong (bass), Joanna Gamble (mezzo-soprano), and Olivia Doutney (soprano). 

The result is an engaging tool that captures the essence of operatic singing through AI-generated voices.
