Overview

The minor triad is one of the four basic triad qualities. Inversions, doublings, and voicings may rearrange its notes, but its root-relative interval structure remains the same.

Construction

The authoritative definition supplies the three chord tones. The minor third establishes minor quality, while the perfect fifth completes the same stable outer frame found in a major triad.

Characteristics

Changing the third from major to minor transforms the chord's quality without moving its root or fifth. Musical effect still depends on voicing, register, timbre, dynamics, and harmonic context.

Applications

Minor triads function as tonic, predominant, dominant-related, or colour sonorities according to context. They also provide foundations for minor seventh chords, arpeggios, diatonic harmonisation, and fretboard study.
