I cannot understand time signatures. Here's what I know.
4/4
The top numbers is the number of beats per measure; the bottom number is the note duration (?). Right? But, I can't seem to apply that knowledge to anything practical. I don't necessarily understand it. Like, how do I count? And is there a certain, um,
speed you should count at? Are time signatures dependant on tempo? I mean, do they have anything to do with bpm? How do you count the weird-looking signatures (6/8, etc). I just bought a metronome. Have no idea what I'm doing with it.
Triplets, etc are also confusing.

Please help.

I'm totally lost. =D
