Meaning of Subdominant Chord in Music
In music, the subdominant chord refers to the chord built on the fourth degree of the diatonic scale. It is called the subdominant because it is the same distance below the tonic as the dominant is above the tonic. The subdominant chord is typically symbolized by the Roman numeral "IV" in a major key, indicating that the chord is a major triad. In a minor key, it is symbolized by "iv", indicating that the chord is a minor triad.
The subdominant chord has a distinct harmonic function and creates a sense of tension and movement away from the tonic chord. It is often used as a precursor to the dominant chord, which creates a strong resolution back to the tonic. In this way, the subdominant chord helps to establish the tonality and structure of a musical piece.
The subdominant chord is commonly used in various musical genres and can be found in chord progressions and harmonies. Its role in music theory is essential for understanding the relationships between chords and creating harmonic progressions.
Example in the Key of C Major
To illustrate the concept of the subdominant chord, let's consider the key of C major. In the C major scale, the fourth note is F. Therefore, the subdominant chord in the key of C major is built on the note F. The F major chord (F-A-C) represents the subdominant chord in the key of C major.
Conclusion
The subdominant chord in music refers to the chord built on the fourth degree of the diatonic scale. It plays a crucial role in establishing tonality and creating harmonic progressions. In a major key, it is symbolized by the Roman numeral "IV", while in a minor key, it is symbolized by "iv". The subdominant chord creates tension and prepares the listener for the resolution back to the tonic chord.
A chord which uses as its root the subdominant note of a key; the IV chord, the chord based upon the fourth tone of the scale.
