Tempo indications have no predictive value in this discussion in that while RSCDS published reels are generally in 2/4 time, often their source tunes are found in 2/2 or 4/4. The same can be found for hornpipes, except for the 3/2 hornpipes already mentioned. As posted before it is not the time signiture that makes the difference between a duple time tune a reel or a hornpipe, but the syncopation. And even there it is the predominance of such that makes the difference, in that a mostly really reel can have hornpipe syncipation occasionally, as can a hornish hornpipe, have occasional bars without syncopation. This follows over into the differench between single and double jig. While they have the same tempo indications, most of the single jigs have a syncipated 4 note rhythm (often shading into a hornpipe when played by traditional musicians - and noted as such on occasions), where the double jig has 6 notes to the bar. As in the above, this is the norm, for a piece of music, and has nothing to do with the exceptions occasionally found.
