Six-line notation is equivalent to looking at the guitar sideways. There are chords on the score, such as G and C. Just press them with your left hand. X is the order in which the right hand plucks the strings. Just press it. When you click a few times, connect them together. The strumming is the up and down arrows, such as ↑ and ↓. I just started looking for some simple bullets and found a good sense of rhythm. I don't know if the explanation is clear.
