What is music sus?

At its most basic definition, a music sus chord is a type of chord that features a suspended fourth note, meaning the fourth note of the chord is raised by one half-step above its typical placement. This creates a chord with four notes that produce rich, varied sounds.

Music sus chords can be played in a variety of ways, and they are often used in various musical genres, from classical to rock to jazz. These types of chords give a certain musical tension that is different from typical major and minor chords, providing a unique and more complex sound.

Music sus chords are often used as transitional or transitional chords, meaning they are used between two chords to create a moment of suspense or tension. They are also used as alternative chords to major and minor chords to add more flavor to a song's harmonic structure.

Overall, music sus chords are important to musical development, giving chords new textures and feelings that musicians otherwise would not have access to.
