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".[citation needed]
In other temperaments
In just intonation a 16:15 minor second arises in the C major scale between B & C and E & F, and is, "the sharpest dissonance found in the [major] scale."[2] <phonos file="Just minor second in scale.mid">Play B & C</phonos>
