So, here's a thought. While we know a few instruments, we don't know much - if anything - about music for a lot of groups. What we do know is that this is a setting with materials with frankly bizarre and physically impossible (or at least to the rules of physics as we understand them) properties and straight-up magic. So, while the natural tendency is to draw from real-world comparisons for 'appropriate' cultures (translation: whatever the people writing think is cool and 'fits'), I wonder if that might not be a mistake, at least for say, High Elf and Draenei. While the Draenei love their harps, why not have bizarre musical instruments built around the crystalline vessels they inhabited? Sounds like a theramin-piano, for instance, working in conjunction with harps, vocalists, and deep resonant bass tones could be astonishing.
