The "Suspended Fourth" is a musical term that refers to a specific type of chord. It is created by taking a major or minor chord and adding a fourth note, which is typically a perfect fourth above the root note. This creates a sense of tension, as the fourth note wants to resolve to a third note, making it a common choice in various musical genres. In practice, the Suspended Fourth is often notated as "sus4" in sheet music. It is frequently used in rock, pop, and jazz music to add color and depth to chord progressions. Musicians use this chord to create a feeling of anticipation before resolving to a more stable chord.
