Which functional chord symbol indicates the subdominant note of a minor key?

• A. I
• B. iv
• C. V
• D. V7

Answer: (B)

In music theory, the functional chord symbol that represents the subdominant chord of a minor key is indeed denoted as "iv." This symbol indicates the minor chord built on the fourth scale degree of the minor scale. In a minor key, the scale degrees are often represented as follows: i, ii°, III, iv, v, VI, VII, where "i" refers to the tonic, "iv" represents the subdominant, and "v" refers to the dominant chord. The "iv" chord consists of the first, third, and fifth notes from the minor scale, forming a minor triad. For example, in the key of A minor, the "iv" chord would be D minor, consisting of the notes D, F, and A. Understanding the roles of these functional chords is important for compositional analysis and improvisation, as each chord serves a specific function and creates different harmonic progressions.
