Mine took me a while. I'll go through my musical career to get to it:
When i was a baby till maybe around 3 or four my mom would play Beethoven's "Moonlight Sonata" on the piano. (To this day it remains one of my all time favorite songs.) I would just sort of wale away at the keys having fun making the instrument make prett noises.
When I started being able to comprehend things a bit better, (I man as well as a small child can comprehend anything) I started off at an early age wanting to play the xylophone, because to me those where the most interesting sounding instruments playing. I thought this because of our high school marching band, and instead of watching the funny formations i was listening to those phones.
Then 4th grade came along and I instead went towards orchestra and wanted to play the Double bass, but because of the expense and my teacher didn't have the knowledge to teach the bass along with the other instruments at the time. So i got the cello. Things went a bit bumpily with it, i didn't hardly practice and i had a couple times where i just plain didn't want to even touch it.
Years later, still playing the instrument. My music teacher, in which I had from 4th all the way till my last year of High school. (Don't ask how this worked, but it did) She helped introduce more of the classical side of music. I had also taken a music theory class and learned more about chords and scales.(This is just a very summarized thing of what i learned)
I had eventually picked up on learning the Bass and normal guitars.
This all may be useless info to some, but to me it's all just the build up to the epiphany that is to come. But so far my biggest epiphany has been, just how amazing a song can sound when just the right amount of harmony, dissonance, syncopation and very passionate individual instrument parts are used. And that the world has become far to structured, and people are too afraid to try anything strange, even things that may not be liked by people. And because of this nothing new and amazing can be made.
