Text: The material of which music is made is tone, in recognizable, orderly chord groups. The simplest chord group is the Triad, or three tone chord. (Also called Fifth, where two thirds makes a Fifth). The Triad always consists of fundamental (root), third and fifth. A Triad may be constructed upon every degree of the scale, Major and Minor. Upon the Major Scale tones the Triads of the key, in C Major, are shown above. These seven Triads occur in exactly the same form in every Major Key. There are three different Triad groupings in the above: Major Triad: Major 3rd and Perfect 5th on the 1st, 4th and 5th degrees. Minor Triad: Minor 3rd and Perfect 5th on the 2nd, 3rd and 6th degrees. Diminished Triad: Minor 3rd and Diminished 5th on the 7th degree.
