A major third is an interval in music that spans three scale degrees. It is the distance between the root and the third note of a major scale. The major third is often considered to be a consonant interval, and it is used frequently in Western music. The term “major third” is also used to describe the interval between two notes that are separated by three half steps.
What is a Major Third?
A major third is a musical interval that spans three scale degrees and two whole tones. It is often described as sounding bright and cheerful.
Here are some key characteristics of a major third:
- Number of scale degrees: 3
- Number of semitones: 4
- Quality: Major
- Sound: Bright, cheerful
Major Third vs. Minor Third
There are two types of thirds: major and minor. The main difference between a major third and a minor third is the number of semitones that separate the two notes. A major third spans four semitones, while a minor third spans three semitones.
This difference in semitones gives the two intervals their distinct sounds. Major thirds sound brighter and more cheerful, while minor thirds sound darker and more somber.
How to Find a Major Third
There are several ways to find a major third on a musical staff:
- Count up three scale degrees from the root note.
- Count up four semitones from the root note.
- Look for the note that is two whole tones above the root note.
For example, if the root note is C, the major third would be E. You can count up three scale degrees from C (C, D, E) or count up four semitones (C, C#, D, E). The note E is also two whole tones above C.
Examples of Major Thirds
Major thirds are used in a wide variety of musical contexts, including:
- Chords: Major thirds are found in both major and minor chords.
- Melodies: Major thirds are often used to create a sense of tension and release in melodies.

- “Amazing Grace”
- “The Star-Spangled Banner”
