Ascending fourth

Definition

An ascending fourth is an interval that spans four scale degrees and is characterized by a distance of five half steps between the two notes. This interval can often be found in music as a way to connect chords in root position, enhancing harmonic movement and adding a sense of lift to musical phrases. The ascending fourth is also integral in establishing tension and resolution within tonal contexts.
