Hi, I'm just going through my music collection and I noticed some versions I have are called "callout hooks". They are short, usually a bit over ten seconds long and contain a part of the chorus. Would someone please explain how these are used? Thanks!
radio ads is probably a tad vague. Commercial radio stations will use a callout hook for ads, to play a snippet of songs coming up next or for surveys and sometimes even for competitions etc. I hope this gives an idea. A type of ad may have several hooks of popular songs to promote say a new club in town.
