The leading tone is the seventh scale degree of the diatonic scale which in F Major is the note "E".
The leading tone of the F major scale is E. In the context of the scale, the leading tone is the seventh degree, which is one half step below the tonic note, F. This note plays a crucial role in creating tension that resolves to the tonic, enhancing the sense of musical movement within the scale.
Generally, the leading note is the seventh tonal degree of the diatonic scale leading up to the tonic. For example, in the C major scale (white keys on a piano, starting on C), the leading note is the note B; and the leading note chord uses the notes B, D, and F: a diminished triad. In Music Theory, the leading note triad is symbolized by the Roman numeral vii°.
