About Blob Opera
Blob Opera is an online music game where you can make your own opera performances by controlling four colorful "Blob" characters.The game was developed by David Li in collaboration with Google Arts & Culture and pairs operatic vocals with machine learning technology to allow players to make music without having to learn how to read musical notation.
The technology behind the voices
A standout feature of Blob Opera is its audio system, built using vocal data from four opera singers: tenor Christian Joel, bass Frederick Tong, mezzo-soprano Joanna Gamble, and soprano Olivia Doutney.
The artists spent hours recording to provide data for the machine learning model. Players do not hear the original recordings directly; instead, the system uses what it has learned about operatic vocals to generate new sounds in response to your movements.
How to play Blob Opera
You simply use your mouse to interact with the four Blobs on the screen. There are no complex control panels or key combinations to memorize. To start writing, do the following things:
Shifting pitch
Drag a Blob up or down to change the note the character is singing. You can experiment with different pitch levels and listen to how the four voices blend together.
Changing the sound
Move a Blob horizontally to switch the vowel sound. Changing the characters' positions can create different nuances for the same musical passage.
Creating harmonies
You don't have to control all four Blobs at once. You can hold some characters steady and adjust the other voices to find a combination you like.
Selecting a stage
Blob Opera has a number of different settings to pick from, including locations based on different cities and performance spaces. Each stage gives the performance its look and feel.
Filming Yourself
When you have created a piece of music that you are happy with, you can record your performance using the recording function. It is also a convenient way to share your creation with friends.
