Tonic, dominant, and subdominant chords are the three main chords that form the foundation of Western harmony. Each chord has its own unique characteristics and function within a musical progression. The tonic chord, which is built on the first degree of the scale, provides a sense of stability and resolution. The dominant chord, which is built on the fifth degree of the scale, creates tension and movement. The subdominant chord, which is built on the fourth degree of the scale, provides contrast and support. Together, these three chords form a harmonic framework that can be used to create a wide variety of musical compositions.
Tonic, Dominant, and Subdominant Chords
These are the three main chords used in western music. They form the foundation of most major and minor scales and provide a strong harmonic framework for melodies.
Tonic
- The tonic chord is the “home” chord of a scale.
- It is built on the first note of the scale and is usually played as a major triad (1, 3, 5).
- Example: The tonic chord of the C major scale is C major (C, E, G).
Dominant
- The dominant chord is the “strongest” chord in a scale.
- It is built on the fifth note of the scale and is usually played as a major seventh chord (1, 3, 5, 7).
- Example: The dominant chord of the C major scale is G7 (G, B, D, F).
Subdominant
- The subdominant chord is the “weakest” chord in a scale.
- It is built on the fourth note of the scale and is usually played as a minor chord (1, 3, 5).
- Example: The subdominant chord of the C major scale is F minor (F, A, C).
Relationships
The tonic, dominant, and subdominant chords have a natural relationship to each other:
- The dominant chord resolves to the tonic chord.
- The subdominant chord leads to the dominant chord.
This relationship creates a sense of movement and resolution in music.
Common Progressions
Some of the most common chord progressions in western music use the tonic, dominant, and subdominant chords:
- I – IV – V – I (tonic – subdominant – dominant – tonic)
- I – V – IV – I (tonic – dominant – subdominant – tonic)
- I – V – vi – III – IV – I (tonic – dominant – minor sixth – minor third – subdominant – tonic)
Question 1:
What are the key characteristics of tonic, dominant, and subdominant chords in music theory?
Answer:
– Tonic chords (T) are the primary chords in a key, establishing the tonal center and providing a sense of stability.
– Dominant chords (D) create a sense of instability and drive the music forward, often leading to the tonic chord for resolution.
– Subdominant chords (S) provide a contrasting element by introducing a different scale degree and adding depth to the harmonic progression.
Question 2:
How do tonic, dominant, and subdominant chords interact in common chord progressions?
Answer:
– The most common chord progression is the T-S-D-T sequence, where the subdominant chord leads into the dominant chord, which then resolves to the tonic chord.
– Variations include adding a ii chord between the S and D chords or using a minor subdominant chord for a darker effect.
Question 3:
What is the significance of the intervals used in tonic, dominant, and subdominant chords?
Answer:
– Tonic chords typically feature the perfect fifth and major or minor third intervals, establishing the tonal center.
– Dominant chords have a major third and diminished fifth, creating tension that drives towards resolution.
– Subdominant chords use a perfect fifth and minor third, providing a contrasting element to the tonic and dominant chords.
