The March, Strathspey and Reel or MSR is a set of tunes consisting of a march, a strathspey and a reel, three different simple time metres.
It is a common format in light music solo bagpiping and pipe band competitions.[1]
Sometimes the march is played separately from the strathspey and reel.
The contrast between the time signatures is an important feature of the MSR.[2]
The other common format for pipe band competitions is the medley.
