D minor

D minor is a musical key centered around the note D, characterized by a somber, melancholy sound. It uses a specific set of notes—D, E, F, G, A, B♭, and C—built in a pattern called a minor scale that creates a darker, more reflective mood compared to major keys. Composers often use D minor to evoke feelings of sadness, introspection, or seriousness. It provides a tonal framework for melodies and harmonies, influencing the emotional tone of a piece of music.
