Maybe this is the cause of my own self-imposed writer's block. Very rarely do I ever write down a musical phrase and a chord progression, because I play it and sing it and think to myself "boy that sounds an awful lot like X".
-As this question depends on how long the song is, I have written a rule at the bottom in which given the number of seconds measuring the duration of the song it is possible to calculate how many songs are possible in that period of time. (The following numbers I work with are also theoretical but will give you a reasonable answer based on the human processing capabilities).
The human hearing range is 20Hz to 20000Hz. Therefore range is 19980 (humans can't detect 10ths of hertz). Humans can hear from 0.00 to 250.00(any greater and you're deaf) decibels.
So that's 25,000 (for the loudness distinguishing). 25000 * 19980 = 499500000
Planck's time (smallest unit of time) is about 3.3 x 10-44 sec. So that would be about (1.64835 * 10^53)*seconds of duration = number of possible songs.
For 2 seconds there are a possible 329,670,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 songs possible, theoretically of course...Read more: Will we ever run out of combinations of musical notes, so that no more new songs can be written? | Answerbag http://www.answerbag.com/q_view/35088#ixzz1nDMbgeyw
What I mean is, we can never truly create something original again. Our minds are stuck in a mode that sees only a small fraction of all possibilities. We might *think* we have all of the base components covered, but we can't, right? There has to be more than this. The phrase "there is nothing new under the sun" might have been the last time there was an utterance of a completely original thought. I'm pretty sure I'm not saying anything that someone didn't already say.
We can. And we will. Scientists are colliding atoms that one day might lead into something new. There are billions of spices waiting to be mixed and experimented on that might cure a disease. One day the common cold will be cured... one day there will be no more cancer... one day there WILL be completely NEW discoveries! Be patient!
