Music museum
Many music museums have musical instruments on display, which gives the sudden urge to play them. In most cases, examples are out there somewhere.
Interactive Music Museum, Málaga, Spain
Interactivity?! Fuck yeah!
Museum of Making Music, Carlsbad, California
This one has a lot of playable instruments. Maybe you could record a song or two using some, or even all of them.
Musical Instrument Museum, Phoenix, Arizona
The granddaddy of 'em all, with instruments from every single country. There's also a room with playable instruments.
