If one knows how to dance, one knows pace, rhythm and timing. In dance, it’s where you put your foot down on the beat. Not so much in ballet but very much present in African-Jazz or pure jazz dance. It’s not a complex concept. Been around for ages. The Brits just express it that way. Look at any Bob Fosse number and that will display for you the sense of prat. Or better yet, go play a dance song, and then DANCE! Congratulations! If you put your foot down on the beat, you're DOING prat.
Baroque music (some of it) depends on prat to keep the rhythms crisp, and, in some cases, turn on a dime, because the composition of some Baroque music depends on exact timing.
