Suspended chords are a type of musical chord that creates a sense of tension and anticipation. They are formed by replacing the third note of a major or minor chord with either the second or fourth note. For example, a Csus2 chord consists of the notes C, D, and G, while a Csus4 chord includes C, F, and G. This alteration gives the chord a unique sound that often resolves back to a major or minor chord. These chords are commonly used in various music genres, including rock, pop, and jazz. They add emotional depth and can enhance the overall feel of a song. Musicians often use suspended chords to create transitions or to build tension before resolving to a more stable chord.
