In modern Western tonal music theory a minor second is the interval between two notes on adjacent staff positions, or having adjacent note letters, whose alterations cause them to be one semitone or half-step apart, such as B and C or C and D.[1] The interval is also called a diatonic semitone.

Its inversion is a major seventh.

A helpful way to recognize a minor second is to hum the first two notes of Rosemary's Lullaby.
