AQA GCSE Music Practice Exam

A major interval is defined as being larger than a corresponding minor interval by a whole tone. For example, if you take a minor third interval—which spans three half steps or semitones—a major third spans four half steps or two whole tones. This distinction is crucial in music theory as it affects the harmonic and melodic qualities of music.

The difference in the size of intervals is foundational to understanding scales, chords, and overall music structure, as it provides the necessary elements that evoke different emotional responses. Major intervals typically sound brighter or more uplifting compared to their minor counterparts, which often sound darker or more melancholic.

Recognizing this relationship between major and minor intervals allows musicians and composers to create desired moods and feelings in their work.
