DescriptionMusic 3-2 set class brightness diagram.svg
English: All variants of the set classes 3-2A and 3-2B, with brightness (sum of pitch classes) depicted by increasing the shade used for each interval. The 3-2A normal form {0,1,3} has a brightness b=4, and 3-2B {0,2,3} has b=5; both are dominated by the large dark-shaded i⟨3,0⟩ interval. Conversely, the bottom left variant {0,9,E} has brightness b=20, and a much "brighter" shading.
