Building Major and Minor Seventh Chords in Music Theory
Seventh chords in tonal music theory constitute a four-note structure formed by extending basic triads with intervals defined relative to the octave. The core mechanism distinguishes three categories based on the quality of the seventh interval: major (11 semitones above the root), minor (10 semitones), and dominant (minor sevenths applied over major triads). These constructs function within harmonic analysis as extensions that generate specific tension levels, with the term "seventh" strictly denoting the interval distance rather than implying a singular chord quality.
