In my experience nearly every Google campus has a music room, and nearly all of them have at least a weighted keyboard.

In the Bay Area there are a lot of acoustic pianos available. There's even a special building that has like 12 practice rooms, each with an acoustic piano.

While an employee, I stashed 6 colored "p-bone" plastic trombones in google colors in various Google Cloud offices... (tokyo has blue, green in UK, etc)

Yeah i was thinking of full size acoustic ones since electronic keyboards are pretty common everywhere

Even some smaller ones too. The Google Montreal office has an excellent music room!

Google Pittsburgh has a music room. We're definitely a smaller office.
