rhythm notation explanation

When I have a moment, I'll write a little more detail. But for now here's a chart showing the different parts of the measure:

 

If what these things are doesn't quite make sense, be sure to read the rhythm primer.

 

The notes above the arrows give you the timing and length of each stroke. Beneath the measure are the arrows. These indicate which direction your arm should move. A down arrow indicates to move towards the ground, and an up arrow means towards the sky. If there are "x"s on the arrow, that means to mute the stroke- sometimes done with the fretting hand and sometimes done with the picking hand. Which, depends on the song, chord, and desired effect.

Sometimes before the time signature, you'll see something that looks like a fancy looking "g". This is called the cleff sign. Or. specifically. the treble cleff. The cleff sign is useful for reading pitches. But. since the strums in this site can be used on any note, chord, or strummed instrument I don't include the cleff sign.
