It may be because I'm a teacher, but I always delight in using educational establishments as role-playing locations. So here is a music school - neglected amidst the plethora of magical academies you can get your hands on, yet music is an important part of most fantasy worlds so people are going to have to learn to play somewhere!
On the face of it, the Grand Conservatory - home to the Musical Society of Drilthenholen - is an absolute feast of musical excellence where music can be studied, played and enjoyed. It has a vast collection of compositions in its library, and you can get instruction in just about any instrument known. Impoverished or ill musicians can get help, too - worth noting as few fantasy societies have much in the way of a welfare state!
But that's the PUBLIC face of the place. Like all really interesting places, there's a lot more going on under the surface... and that presents plenty of opportunity for adventure, and provides the potential of making the Conservatory an important location in your campaign world, should you like intrigue and adventure where brains are at least as useful as brawn.
System free notes are provided on major individuals who work or frequent the Conservatory, along with six scenario seeds (which all sound rather fun, if you make the Conservatory an important location that the characters visit often, you might well be able to make use of all of them) as well as a couple of magical items, rumours and encounters and a plan of the Conservatory itself.
I like music, and playing bard or minstrel characters, so I think this will find a place in at least one of my games!
