Blob Opera

Google's Blob Opera lets you sketch little vocal pieces with four wobbling singers. Each blob covers one opera range, from bass up to soprano, and real recorded voices give the notes their stage-sound edge. Drag them around, stack odd harmonies, test long vowels, or let the group slide into something surprisingly polished. Hit the holiday icon when you want preset Christmas songs sung by the same rounded cast. Save what you make and play it back like a tiny opera experiment.

How to play?

Look over the quartet, then click or tap one singer. Pull upward to raise pitch. Move sideways to swap the vowel sound. Try another blob and build the chord a voice at a time. Pause on different positions to hear how the group blends. Use the recording option when the melody sounds right. Tap the tree icon for seasonal presets, then edit the arrangement from there.
