Timbre as Drama

Change the instrument under a theme and the character, the situation, changes with it.

The problem

A theme played by a horn and the same theme played by an English horn read as two different people. Orchestration must answer not which colour is prettier but who speaks now, and from how far.

How it works

Dramatic timbre rests on role, state and distance. Fix one instrument to a character and, when the character changes, change the colour before the melody. Register and articulation alter the personality of a single instrument; a soft horn blends into woodwind, while the same note forced loud sounds like someone else. Solo against tutti marks a change of scene. Place colour changes on phrase boundaries, or the ear hears only a patch change.

Settings and judgement

Choose two or three main colours per scene. Contrast through register, legato against staccato, and mutes rather than a new instrument. Give each character a register of its own so two roles do not cover each other. Eyes closed, can a listener name who is speaking?

What to listen for

In In the Steppes of Central Asia the English horn states the theme before strings and tutti take it; hear one melody change personality. In Scheherazade the solo violin confronts the brass, marking the storyteller's distance. The Sorcerer's Apprentice rotates woodwind, harp and glockenspiel, advancing the scene by colour.

Common misconceptions

That more instruments mean more drama. Listeners remember one colour as one person; colour changes without rhythmic or harmonic support merely sound like a patch change.
