So, I've been recording and crit-ing for a few weeks... and I've heard the phrase "song Dynamics" come up a lot. So, I was wondering... WTF does that mean?

Please keep in mind that I know next to nothing about music... like, I'm so poorly intellectual about it... that I don't even know what note is what on a guitar... I just play by what sounds good, and where the tabs tell me to put my fingers. I don't understand time signatures either... I just basically play until something sounds right... so please don't bash me on either of those cases.

anyone care to explain?
it means like: loud and soft, fast and slow, heavy and soft. stuff like that
