This is an excellent eclectic collection of musical instruments to keep any bard character entertained as he decides what to play in his next concert... and there are some really unusual ones that are maybe better suited to a far future campaign - after all, there will still be a need for musical entertainment.
It can be amusing in game too... I once put a #35: Laser Harp in the corner of an abandoned alien spaceship some of my Traveller characters were investigating and had quite a lot of entertainment as they tried to figure out what it was from the description. (If you don't know, watch a Jean Michel Jarre concert, it's the laser beam array that he 'plays' by breaking the beam with well-gloved hands!)
Some are more or less different names for the same thing. A Moog is just a kind of synthesizer, for example. And someone needs to pay attention to odd characters, as the A-sharp (or is it A-flat?) clarinet has come out as A? clarinet which leaves me little the wiser (possibly like the seagull which has just perched on top of the chimney on the Sistine Chapel roof - I'm writing this as the Papal election is in progress with a webcam window open to check for smoke!).
Pass me my Balalaika and I'll play you a tune!
