I too first thought this was about electrical cords (forgot the "h" in there) laying out right angles and parallel's, but then I started to read the post and really got lost, no high level training here. Angular contains angle and then there's 360 degrees and I'm still trying to figure out where a chord expresses itself in all these movements, but inverted or a simple triad if it doesn't sound right, it probably won't compliment the music and melody line. My question is did Brian Wilson really know what he was playing technically or simply write a song that sounded good to his ears...playing by ear.
