"Piobaireachds (piobrochs) were often written to commemorate an event (e.g., Laments for death are very common) or had practical uses in Highland society (e.g., Gathering of the Clans). These tunes are generally several minutes in length and, when well played, are some of the most inspiring music of the bagpipe".

I am not a piper but that may explain the tradition of the Scots or those of Scottish decent having a piper "to pipe them home".
