* Root: The root is the lowest note of the chord and is the same as the first note of the corresponding diatonic scale.
* Third: The third is the second note of the chord and is related to the root by a third, which can be either major or minor.
* Fifth: The fifth is the highest note of the chord and is related to the root by a fifth, which can be either perfect or diminished.
The quality of a diatonic triad is determined by the interval between the root and the third. If the interval is a major third, the triad is a major triad. If the interval is a minor third, the triad is a minor triad.
The diatonic triads that can be formed from a given major scale are as follows:
* Major: C major, D minor, E minor, F major, G major, A minor, B half-diminished
* Minor: A minor, B half-diminished, C major, D minor, E minor, F major, G major
The diatonic triads that can be formed from a given minor scale are as follows:
* Minor: A minor, B half-diminished, C major, D minor, E minor, F major, G major
* Major: C major, D minor, E minor, F major, G major, A minor, B half-diminished
Diatonic triads are the most common chords used in Western music. They are used in a wide variety of musical contexts and are essential for understanding and creating harmony in music.
