The Pipe Sergeant, commonly abbreviated as "P/Sgt", is the number two person in charge of the pipers in a Scottish pipe band or pipes and drums. In terms of seniority, the Pipe Sergeant is secondary only to the Pipe Major, who is the director of bagpipe music in a pipe band. A Pipe Sergeant shares much of the Pipe Major's responsibilities in tune selection, compilation and arrangement. He or she is responsible for tuning up the band before a performance.
