A minor interval is a musical term that describes the distance between two notes. It is one of the basic building blocks of music theory. In Western music, a minor interval typically consists of two notes that are a whole step and a half step apart. For example, the interval between the notes C and D♭ is a minor second, while the interval between A and B is a minor third. Minor intervals are important in creating a sense of tension or sadness in music. They are often used in various genres, including classical, jazz, and pop. Understanding minor intervals helps musicians and composers create more expressive melodies and harmonies, enhancing the emotional impact of their music.
