When elbow or knee deep in VBA coding I like to drown out noise from others so will usually listen to either 80's music or rock. Blink 182 is usually the band of choice (love the drumming and power chords). I can also shut the door to my office if things are a bit noisy (luxury!).
I have often wondered why music? What is going on with the body that makes us choose music through headphones? How does bombarding ourselves with music help us concentrate more?
I think we want to control the noises we are hearing, which we couldn't normally do. Our subconcious can readily pre-process the noises we are about to hear, being music we are familiar with. Given we know the sounds that are coming we don't have to concentrate on them and we don't have to consciously process any unexpected noise. In effect we are blocking one of our senses so that we limit the amount of external uncontrolled information received (to almost nothing given we are visually glued to the screen). Which means we can concentrate more on what we are trying to do (hence the 'concentration' music).
Some personal observations that this:
1) try it with unfamiliar music and it doesn't have the same effect;
2) the speed with which the songs seem to fly by (just the one chorus!?),
3) the inability to recall in sequence the songs you have just listened to, and
4) the number of seconds it takes to re-engage your brain to an external interruption (e.g. a simple question like "tea or coffee?" - it may take say 5 seconds to respond.)
