In Noctem (from Harry Potter & the Half-Blood Prince). Music by Nicholas Hooper, lyrics by Steve Kloves / arr. Tom Gerou. This beautiful & haunting melody is featured in Harry Potter & the Half-Blood Prince. This arrangement is set in traditional five-finger style, with the melody split between the hands, & without a key signature in the student part. Dotted quarter notes, triplets and sixteenth notes have been avoided. An optional duet accompaniment is provided for a fuller, richer experience.
