To the musician, the set list for any given performance can help them remember what songs to play, in what order and in what key. Sometimes notes are added as to who sings or plays during that song. The set list can be a constant reminder of what to do so that they can focus on playing the music without thinking “Oh Shit, what’s next?” Set lists are not always followed exactly, for example troubadour folk singer Ramblin’ Jack Elliot often does set lists, but usually doesn’t follow them. He jumps around, singing songs that may or may not be on the list, often taking requests from the audience or completely ignoring a song he was set to play in lieu of another.
