I think I understand the timing a little bit better after a brief lesson. I played an easy song, "A Horse With No Name." It's very simply. Only two chords throughout the entire song but as the lesson stresses, a song is not a song if it is not in rhythm. "The rhythm of the song is in 4 / 4 time (four beats per measure) and the chords change each and every measure." Any guitarists out there care to give a little explanation? I understand a little and try to count along with the strokes 1..2..3..4, then switch to the other chord and do the same thing. I could be counting at an incorrect pace though...
