The Manehatten Musical Academy; specializing in String, Brass and Wind instruments. Though a quick glance at their pamphlet showed they had courses and classes for most mainline instruments, for those with a less career-centric, and more hobby-focused interest. I heard a few requests to try some of the instruments, but thankfully, they're pretty stingy about doing anything more than showing them off, pulling them back whenever an excited foal or pony tries to reach for them. I think they even write out a 'Do-Not-Touch' sign, slapping it to the front of their booth. My ears appreciated that.
