Hi Grant
So how about, “ the association of a music and sound with a product, company, or broadcast program.”
A variant of this is assocaition is an “Earcon.”
An “Earcon” is the audio branding signature that is played to identify/reinforce a product. Think of using a pay-phone a few years back and hear “AT&T;… >perdlewing<” , Duracell Batteries “Peern, peern, PEERN” or Intel’s four note cadence. You can take this all the way back to the NBC earcon, though they never called it that, which were the notes G-E-C (picture the peacock) because they were owned by General Electric Corp!
I have recorded Earcons for a variety of companies and it is very interesting how many pick very “retro” sounds. (I don’t complain… if they realize that their earcon sounds “dated” in a year, they come back to me looking for something more “progressive.”
