What is a melodic hook?

Answer 1

Hooks: repeated melodic, lyrical and rhythmic devices that are usually the most memorable part of most pop songs. These include:

melodic hook: hook based on the instruments and the singers

rhythmic hook: hook based on the patterns in the drums and bass parts

verbal hook: hook based on the rhyming and/or repeated words of the chorus

I take it that the harmony he created to the main hook resulted in a sound like brass instruments.

(I often use 'brass' to refer to money - usually in the negative - 'I haven't got any brass, have you'?)
