The song is performed by Dexter's piano teacher, Professor Williams, as an ode to music's compatibility with science. Dexter and Williams both sing parts of the song; Williams plays the piano, while Dexter uses a piece of laboratory equipment to provide an instrumental break. The song receives a brief reprise during the episode's end titles.
Professor Williams: When my music meets your science,
they're the biggest of the giants
and they'll solve all their problems and throw their troubles away.
When you take the math you know next to do re me fa so
you can mix them all around and make some music to play.
Tomorrow is a brighter day if we work together.
Together we can pave the way it'll last forever.
Just open your heart, unlock that prison deep down in your mind
step up to your console, make some music and breath in the good sunshine.
Tomorrow is a brighter day
Dexter: if we work together.
Together we can pave the way
Professor Williams: it'll last forever.
Both: Just open your heart unlock that prison deep down in your mind
step up to your console, make some music
and breathe in the good sunshine!
