Scale Degrees
The name and role of each note in a scale, from the tonic to the leading tone.
Once you can name the notes of a scale, the next step is understanding what each note does. Every note in a scale has a number and a traditional name that describes its musical role. Together these are called scale degrees, and they are the key to hearing why music feels tense, restful, or pulled in a certain direction.
Numbers and carets
In a seven-note major or minor scale, the notes are numbered 1 to 7 starting from the note the scale is named after. To show that a number means a scale degree rather than an interval or a fingering, musicians write it with a small caret above it, so degree one looks like 1̂ and degree five looks like 5̂. After 7 the pattern repeats: the eighth note is 1̂ again, one octave higher.
The seven names and why they matter
Each degree also has a name that hints at its function. The most important idea is home. Degree one is the tonic, the note the whole scale gravitates toward and the note a piece usually ends on. Everything else is heard in relation to it.
- The dominant (degree 5) creates the strongest pull back toward the tonic. Chords built on it want to resolve home, which is why it drives so much harmony.
- The leading tone (degree 7) sits just a half step below the tonic, so it feels unstable and seems to lean upward, wanting to resolve to 1̂.
- In natural minor, degree 7 is a whole step below the tonic instead of a half step. Because it no longer leans up as strongly, it is called the subtonic rather than the leading tone.
All seven degrees in C major
| Degree | Name | Note in C major | Role |
|---|---|---|---|
| 1̂ | Tonic | C | Home; the point of rest everything resolves to. |
| 2̂ | Supertonic | D | Just above the tonic; often leads into the dominant. |
| 3̂ | Mediant | E | Midway between tonic and dominant; colours the scale as major or minor. |
| 4̂ | Subdominant | F | A gentle departure from home; balances the dominant. |
| 5̂ | Dominant | G | The strongest pull back to the tonic; the engine of tension. |
| 6̂ | Submediant | A | A softer, often more lyrical degree; the relative-minor home. |
| 7̂ | Leading tone | B | A half step below the tonic; leans strongly upward to resolve to 1̂. |
Notice the names above and below "dominant": the subdominant sits a fifth below the tonic just as the dominant sits a fifth above, and mediant and submediant sit a third above and below. The naming mirrors the structure of the scale itself.
Hear it for yourself
The best way to make these labels real is to play scales and listen for the pull. Use the scale explorer below: play a major scale up to degree seven and stop. You should feel it straining to go one more step up to the tonic, because degree 7 pulls up to 1. Then play degree 5 followed by degree 1 and notice how the dominant settles onto home.
Scale explorer
Choose a root and scale to see and hear it, spelled correctly.
Try the same in a minor scale and listen to how the flattened seventh, the subtonic, leans up far less than a leading tone. Once you can hear these tendencies, scale degrees stop being labels and become a map of where the music wants to go.
