Tiny music challenge

By which I mean, who can name the tiny musics in this clip?

The percussive noises in the background come from the birds of Hyde Park, in Perth, where this monolith hovers (around its foot frolic tiny ape-creatures, dancing to Strauss). I guess all of them are corporate. I only recognise a few, though – any clues?

Bonus points if you can spot my favourite one.
