About Minor Second

The minor second is the distance between any two adjacent notes in the chromatic scale — C to D-flat, E to F, or B to C, for example. It produces a sharp, tense, dissonant sound when two notes a minor second apart are played simultaneously, and this dissonance makes it one of the most expressive intervals in music.
