This four parts jig was composed by Pipe Major Alexander “Sandy” Hain (from a family of pipers) in honour of another piper, Donald McKillop.
As for the Reels, there are many tempi to play a jig, ranged from about 110 to 136, according to the piper or his audience (dancers or listeners).
The tune is of course essential for choosing a beat.
That being said, tempi under 130 are often a good option to preserve all the musicality and the grace notes clarity.
We can even agree on a range of 112 to 120-122 bpm.
NB: the score displayed on the tutorial bellow has some slight differences with the tune i've heard played by PM Bill Robertson.
