Daws with Live style looping pattern mode.

[zzz00m]

Patterns are what catches our ear and makes a song appealing, and has usually played a big role in pop hits.

A hook is a memorable musical idea commonly used in popular music, including non-electronic forms. For example, it could be a short guitar riff played over and over. Which could simply be a one to several bar repeating pattern not involving repeat signs.

That is a form of loop.

My point was that patterns are everywhere in music, and loops are just a smaller pattern.
