Pipe bands play a variety of tune types. When they are not marching, they form a circle and the Salute has been titled a Circle tune. It has also been composed for use by lone-pipers.
Note for non-piping musicians. The grace notes or twiddly notes don't affect the bar addition as they are to be ignored. They, of course, "rob" the following proper note.
See a list of Circle tunes here , second section - Sets are,on the right of the page.
Here is the score for pipers: The audio tune above is set at 125 bpm and is a bww.file. Keen musicians will see that the audio version above differs from the score. My IT skills don't reach the level needed.
