Hedwig's Theme (from Harry Potter and the Half-Blood Prince). Music by John Williams / arr. Tom Gerou. Introduced in the very first Harry Potter movie, "Hedwig's Theme" has been featured in each installment of the cinematic franchise. The magical and wizard-like melody is a favorite of all Harry Potter fans, young and old. This arrangement is set in traditional five-finger style, with the melody split between the hands, and without a key signature in the student part.
