A triad chord has three notes: a root, a third and a fifth. The root depends on the scale name. Lets use C major as an example, the root would be C. The third can be either a minor third or a major third, if it was a minor third I would use E flat. I will use E as the third. Next is the fifth. There are many types such as a diminished fifth, augmented fifth, and perfect fifth. For simplicity’s sake I will use the perfect fifth of C major: G. If I put all these notes together, C,E and G, this will make a major triad. If the notes were C, E flat and G, it would be a minor triad. I will use this page to gain more knowledge on triads.
