I'm not sure if this is where this topic belongs, but I'm curious; What exactly is a Bright or Dark tone? My band director says that my low register is dark, but my high register is the opposite, bright. Honestly, I can't tell. But what I want is my tone to be dark on all registers. What causes it to be split like that? Is there anything I can do without buying a new horn? Can someone post some examples of bright and dark toned players?
