Q: I like how news programs on tv always have some music with that dramatic one-note staccato type riff. Like BAH-da-da-da bah-DA-da-da-da BREAKING NEWS..
A: traditionally those shows had just the sound of typewriters in the background for the opening titles. i believe the music evolved as an emulation of that soundtrack. it also resembles morse code, which was no doubt a defining sound in the news industry at one time
