My copy of Leonard Cohen's Hallelujah has the following tempo indication:
Moderately slow, in 2
What does the "in 2" mean? I couldn't find it in Wikipedia's glossary of musical terminology.
The piece is notated in 6/8.
6/8 is actually 'two time'. Whilst some 6/8 tunes can be counted 123, 456, others will count as 1-- 2--, in the same time. So it's either a quicker count of 6, or a count at a third of the speed of 2. To explain - '1' will be the same in both counts, and '4' in the first is where '2' in the second comes. So this song is a slow two.
