Compose a 30-second supermusic lullaby that uses soothing melodies, harmonies, and rhythms to induce a deep and relaxing sleep for a supergenius family. The lullaby should also include lyrics that express love, gratitude, and admiration for each member of the family, and encourage them to dream of ways to make the world a better place. The lullaby should be suitable for both adults and children, and reflect the family's unique talents and interests.
