Firework: SSATBB, a cappella Choral Octavo

Ben Bram's arrangement respects the original's explosive energy while adapting it intelligently for six-part voices. The chart captures what makes this song resonate with singers and audiences alike: propulsive rhythms, clear melodic hooks, and that unstoppable build toward the chorus. This is pop arranging that doesn't strip away the song's appeal in pursuit of vocal sophistication.

Exhilarating and polished. The track builds from a tight, propulsive foundation into something that feels celebratory and inevitable, with that rush of momentum that made the original a global hit. You feel the shape of the song even without instruments.

Pop a cappella groups looking for a contemporary arrangement that audiences will instantly recognize and singers will enjoy performing. This works for intermediate to advanced choirs with solid blend and the ability to maintain rhythmic independence across multiple voice parts.

• Anchor the rhythmic precision in your lower voices. SSATBB balance hinges on the bass and baritone locking the groove so sopranos can soar over it.
• Shape the energy across the arc of the piece. This song lives in dynamics and intensity; resist the temptation to sing full volume from measure one.
• Treat the recorded example from Eleventh Hour as a listening reference, not a performance template. Let your group's sound and pacing emerge from your own rehearsal process.
• Pay attention to vowel matching across the six parts, especially in the densest passages. Blend becomes harder at higher volumes, so unify your vowels first.

Pair this with other contemporary pop selections to anchor a modern music segment of a concert, or use it as an encore that energizes your audience. The familiarity of the song makes it ideal for outreach performances where you want to connect with listeners who don't typically attend vocal concerts.

• Maintaining steady rhythm in mixed meters and syncopated patterns across six independent voice parts
• Balancing blend and tuning in a six-part texture without instrumental support
• Shaping large-scale dynamic arcs and energy in contemporary music
