Dynamics and Their Affect on Attention

Ok the subject of this first post is dynamics! Not just dynamics in volume but in all aspects of sound. In order to save processing power and increase efficiency, the brain is programmed to acclimatize itself to static sounds. (or any static stimulus really, but we're talking about music) In the same way you grow to take something for granted, your mind will pay less and less attention to something if it does not change perceptibly over time. This is due to the fact that it can't spend attention on everything and if there's no change then there's no point in continuing to report that stimulus. Think of going to visit a website every day to check if they've published a new article. Day after day you check and most days there's nothing new. Instead of wasting your time and resources you decide to subscribe to the page by rss and ignore it until you're notified something new has been added. This is similar to how the brain handles input.
