  • The quality of an interval is also influenced by accidentals. The major can become minor and vice versa.

    Hence if

    • the upper note of a major second is lowered or the lower note is raised it becomes minor second
    • the upper note of a minor second is raised or the lower note is lowered it becomes major second
    • both notes have same accidental, the interval (distance) doesn't change
