Question
In harmony: triads
Answers
GPT-4o mini
In music theory, a triad is a set of three notes that can be stacked in intervals of thirds. Triads form the basis of harmony in many styles of music. Here’s an overview of triads, including their types and how they are constructed:
### Types of Triads
1. **Major Triad**: Consists of a root, a major third, and a perfect fifth.
- Example: C Major (C, E, G)
2. **Minor Triad**: Consists of a root, a minor third, and a perfect fifth.
- Example: A Minor (A, C, E)
3. **Diminished Triad**: Consists of a root, a minor third, and a diminished fifth.
- Example: B Diminished (B, D, F)
4. **Augmented Triad**: Consists of a root, a major third, and an augmented fifth.
- Example: C Augmented (C, E, G#)
### Construction of Triads
- **Root**: The primary note upon which the triad is built.
- **Third**:
- Major third (4 half steps) above the root for major triads.
- Minor third (3 half steps) above the root for minor triads.
- **Fifth**:
- Perfect fifth (7 half steps) above the root for both major and minor triads.
- Diminished fifth (6 half steps) for diminished triads.
- Augmented fifth (8 half steps) for augmented triads.
### Inversions of Triads
Triads can be played in different inversions based on which note is the lowest:
1. **Root Position**: The root note is the lowest.
- Example: C (C, E, G)
2. **First Inversion**: The third of the triad is the lowest.
- Example: C/E (E, G, C)
3. **Second Inversion**: The fifth of the triad is the lowest.
- Example: C/G (G, C, E)
### Function in Harmony
Triads are often used to create chord progressions, which are sequences of chords that provide a harmonic foundation for melodies. They can also provide tension and resolution, making them essential in the context of Western tonal music.
Triads are commonly indicated in music notation using chord symbols (e.g., C for C Major, Am for A Minor) and can be represented on guitar, piano, and other instruments.
Understanding triads is fundamental for composing, arranging, and analyzing music, as they are the building blocks of harmony.
