The fifth note or chord in a scale

In music theory, the term "dominant" refers to the fifth note or chord in a scale, which is commonly considered the strongest and most important note or chord in tonal music.

The dominant typically produces a strong sense of tension, and its primary function is to prepare the listener for a return to the tonic note or chord.
