Compose? It's only 3 notes in a pre defined order, is that composing?

Of course BBC Local Radio has a B B C motif in its jingles (although I'm not musical, not sure if it is actually the notes B B C)

I guess the composing part is looking at things like how you space out the notes and the instruments chosen rather than just the notes themselves.

The visual equivalent would be that there's more to the BBC logo than just putting 3 letters together onscreen.
