Prism

Prism is about the hidden spectrum inside a single thing. Hold one beam of white light up to the right angle and it shatters into every color at once, and that's the whole idea of this show: one melody, refracted again and again, revealing a different shade of itself each time. It's a production about how much color lives inside something that first looked plain, and how a single idea can bloom into a spectrum.

This show was designed for small bands to be successful. The score includes parts for all instruments, but there is significant doubling across those parts, so any combination of instruments, including less-than-ideal instrumentation, can carry the show in performance.

On the field, the metaphor is built into the props: prism forms that catch and bend the light, and as each color is "refracted" out, another version of the show's central tune emerges, recolored, recast, seen from a new angle. The through-line is Chicago's Colour My World, and the fun of the show is watching one familiar melody turn into a dozen different colors of itself. Underneath, the harmonies carry echoes of music you'll recognize without quite naming, more light bent through the same glass. It's a warm, visually striking, endlessly colorful production that scales cleanly to a band of any size.

The music:

• Colour My World (Chicago)
• Prelude in C (Bach)
• Original writing by Ryan

This show is rated Medium-Advanced, which lines up with a concert grade of roughly 2.5 to 4.5. That's an approximation. A featured soloist or small ensemble moment can sit toward the top of that range, while full ensemble sections built around visual impact stay lighter on the musical demand.

The rating leans almost entirely on rhythmic and technical difficulty. Keys and meters are chosen to stay band-friendly and to line up with the phrasing the drill needs, and instrument ranges sit inside the grade window rather than pushing its edges.

Permissions to arrange are required for the Chicago selection. Bach's Prelude in C is in the public domain.
