The chord Dsus4 is a suspended fourth chord built on the note D. It consists of the notes D, G, and A. The term "suspended" means that the third note, which would typically be F# in a standard D major chord, is replaced by the fourth note, G. This creates a unique sound that adds tension and anticipation, often resolving back to the D major chord. Dsus4 is commonly used in various music genres, including rock, pop, and folk. Musicians often employ this chord to create a sense of movement in their progressions. It can be played on various instruments, such as the guitar and piano, making it a versatile choice for songwriters and performers.
