leading note

In music, a "leading note" (or leading tone) is the seventh note of a major or minor scale. It has a strong tendency to resolve to the tonic, the first note of the scale, creating a sense of harmonic movement and tension and release. This interplay between consonance (stable sounds) and dissonance (unstable sounds) is fundamental to harmony. While dissonance was once strictly controlled, composers have long used it to create musical interest and drive. The leading note, as part of chords like the dominant seventh, plays a crucial role in guiding the listener's ear toward the tonic, contributing to the overall structure and emotional impact of a musical piece.123
