The interval between the ninth harmonic (9X) and the eighth harmonic (8X) gives the major second interval.
The interval covers two white positions of the C major scale.
There are two semitones spanning the notes of a major second interval.
This major second distance between the root and second notes of chords are known as suspended chords.
The frequency ratio of the major second is 9X/8X= 9:8.
A major second is equal to a Tone.
A minor second is equal to a semitone.
