The C major scale is the simplest in Western music — seven white keys, no sharps, no flats. It's where every theory student starts: the natural reference for what "major" sounds like. Every other scale is, in some sense, measured against this one.
Interval pattern
The C major scale is built from this fixed pattern of whole steps (W) and half steps (H):
- Wwhole
- Wwhole
- Hhalf
- Wwhole
- Wwhole
- Wwhole
- Hhalf
Every major scale uses this same pattern, transposed to start on a different tonic. The half-steps fall between scale degrees 3–4 and 7–8.
Scale degrees and intervals
Each note of the scale, with its scale-degree name and interval from the root:
| Degree | Note | Interval from root | Function |
|---|---|---|---|
| 1 | C | Root | Tonic |
| 2 | D | M2 | Supertonic |
| 3 | E | M3 | Mediant |
| 4 | F | P4 | Subdominant |
| 5 | G | P5 | Dominant |
| 6 | A | M6 | Submediant |
| 7 | B | M7 | Subtonic / Leading tone |
In melody and improvisation
Beginning piano repertoire from Bach to The Beatles is full of C major. It's the default key for sight-singing, ear-training drills, and theory examples because there's no key-signature distraction — every note is exactly what it looks like. The relative minor (A minor) shares the same notes; only the centre of gravity shifts.
Relative key
The C major scale shares its notes with A minor. Same seven pitches, different tonal centre — when a piece moves between them, no accidentals change.
Common mistakes
Beginners sometimes assume "white keys = C major", but A natural minor uses the same seven notes. What makes a scale a *scale* is its tonic — the note the music resolves to. Watch for B → C as the half-step that gives the scale its strong leading-tone pull.
Drill it
The Interval Trainer gives you a root note and an interval, and asks you to name the result. Practising the intervals of the C major scale is the fastest way to internalise it as a melodic shape rather than a memorised string of notes.
