@Tuxedokman you bring up some fantastic points that I neve considered before. It is unlikely that the Lizardmen could (in the real world) use anything resembling a blowpipe or a flute, simply because of their anatomy. They very well would probably be restricted to drums or gutteral cries/screams. Maybe even a xylophone type of instrument? Or a pipe organ? Anatomical issues aside, my favorite music to play in reference to the Lizardmen is from the old Pitfall: Mayan Adventure game. Here is an example: Link to the thread where I posted more info on this game. Its pretty old at this point... so many memories!
