Using two horizontal and two vertical lines to organize your art work, is using this general guideline: a) space
b) the elements of art
c) composition
d) the rule of thirds

It depends on what type of third separates the three notes.for example: if you have two mayor thirds is an "aumented chord"if you have two minor thirds is an "diminued chord"if you have one mayor first and then one minor is a "mayor chord"and inverted is a "minor chord"
