was passing thro' and saw this.
yep, you got what a loop is. it's a sequence of one or more bars repeated. used in sequencers - computer software used to compose music either using notation like finale or piano-roll like cubase where you draw the duration of your notes along a grid.
it gets its name from the way its done - you compose what instruments you want to happen where in the bar(s) then join the end up to the beginning so it repeats [ the computer does that for you]. you can literally have it running though the entire song or use it just when you need it. most composers intermix several loops to prevent monotony or make the loop 4 bars long to give variation.
any help?
