Not just Rock or Pop. Any piece of music you like the “hook” for.
Some of mine:
The William Tell Overture bit used for The Lone Ranger
The basic riff in Pink Floyd’s Money
The riff in the Beatles’ Day Tripper
The intro to the Doors’ Riders on the Storm
There are at least 50 I could name without slowing down.
What makes a hook catchy? The beat? The melody? What?
