The major second (M2) is one of the most common melodic intervals in tonal music. It spans 2 semitones and is the basic whole-step motion that drives scales, melodies, and smooth voice leading.
Construction and spelling
M2 runs from a note to the next letter name, such as C to D, F to G, or A to B. In interval quality terms, it belongs to the major/minor family. Keep note spelling consistent with key context so analysis and notation stay clear.
Harmonic and melodic usage
Melodically, M2 creates natural stepwise movement and flowing lines. Harmonically, seconds can add gentle tension in clusters or suspensions, especially when voiced closely. In functional harmony, whole-step motion is central to melodic resolution and phrase shaping.
Examples
- Scale passages built from consecutive whole steps and half steps
- Stepwise melodic writing in vocal lines and instrumental themes
- Neighbor-note figures and suspensions resolving by step
In practice
Practice M2 ascending and descending from many roots, then identify it quickly by ear in melodies. Compare M2 with m2 to hear the difference between open step motion and tighter chromatic tension. Strong M2 control improves intonation, phrasing, and melodic fluency.
