The music director for both seasons was Suguru Matsutani. As with the live-action drama, several works of classical music were featured in each episode, performed by the Nodame Orchestra. The opening theme of season one was "Allegro Cantabile" by Suemitsu & The Suemith, and the ending themes were "Konna ni Chikaku de..." by Crystal Kay (episodes 1–12), "Sagittarius" by Suemitsu & the Nodame Orchestra (episodes 13–22), and "Allegro Cantabile" by Suemitsu & The Suemith (episode 23). The opening theme for the second season was "Sky High" by The Gospellers (with melody taken from the Third movement ("Allegro Scherzando") of Rachmaninoff's Piano Concerto No. 2), and the ending theme was by Emiri Miyamoto x solita (with variations on the theme from Ravel's "Boléro"). The opening theme for the final season is "Manazashi Daydream" by Yuu Sakai (with variations on the theme from Bach's "Jesu, Joy of Man's Desiring") and the ending theme is "Kaze to Oka no Ballad (風と丘のバラード)" by Real Paradis with Nodame Orchestra.
