Subdominant

In music, the subdominant is a specific chord that provides a sense of movement and stability, acting as a bridge between the main key (the tonic) and other chords. It is built on the fourth note of a scale and is often used to create a feeling of expansion or preparation before returning to the main key or moving to other chords. Think of it as the sound that gently shifts the music forward, adding emotional depth and variety without causing tension like some other chords do. It plays a vital role in shaping the overall musical harmony.
