Blob Opera: a corner simulator game where you can create your own opera
Blob Opera is a singing game or experiment developed by David Li in collaboration with Google Arts & Culture where you can create your own opera using four singing bubbles.
The game has a brief tutorial introducing the four voices and showing how you can create your own opera using the mouse. The up and down positions change the note within a scale and the left and right options change the sung syllable.
The combination with the notes and syllables, using the time and the division of the voices give your music, even without any skill, a real appearance.
