that's it! the phrase "enhanced performance"- that's what an arranger gives us..it is presumed in the phrase that we know how to perform. If we don't know how to perform, and use the backgrounds as the presentation, then we are not really musicians. But if we know how to make music on our own, then the arranger enhances what we do--that's the art of arranger playing. but that presumes there is an audience that appreciates the difference
