The Cymbals

I piatti — the plates.

Two great discs of bronze, struck together or struck alone: the orchestra’s brightest metallic voice, and one of its oldest. Capable in turn of detonation and of light.

The cymbals are the orchestra’s brightest metal — two hammered discs of bronze, broad as dinner plates, struck together by their leather straps or singly with a stick. They give no pitch and yet they give light: a single full crash will halo a tutti, and a long suspended roll will fill a soft passage with what feels almost like weather.

Like the bass drum, they came late and from elsewhere. The instrument of the modern orchestra is essentially the cymbal of the Ottoman Janissary band, recast in larger bronze and given over to symphonic purposes. Berlioz was the first to take it seriously; Tchaikovsky and Rimsky-Korsakov, the first to take it for granted. Every composer since has had to negotiate with that inheritance.

Mechanism

Each cymbal is forged from a single disc of bell bronze — most often the alloy known as B20, four parts copper to one of tin. The disc is hammered, heated, lathed, and finally pierced at its centre for a small dome — the cup — through which a leather strap is fed. The pair is held by these straps, never by the cup itself, and never with rigid handles: the cymbal must be free to vibrate.

Two principal voices coexist in every part. The piatti a 2 — the pair, struck together — gives a clashed sound of brief attack and long shimmer. The piatto sospeso — a single cymbal hung on a stand and taken with mallet, stick, or brush — gives almost any sound the player wishes, from a faint metallic breath to a full crescendo roll. The composer who wishes the second must write it; in silence the player will assume the first.

Voice and Character

The clashed pair is the most articulate fortissimo in the orchestra. Berlioz, who knew the instrument intimately, observed that the cymbals reinforce the orchestra most happily in passages of a brilliant or pompous character — and reproached the composers of his day for clashing them on every available downbeat. The reproach has aged well. A pair of cymbals struck once is an event; struck twice in the same phrase, almost never.

The suspended cymbal is a different instrument altogether — quieter, more atmospheric, susceptible to the smallest gradations of touch. A soft yarn mallet drawn slowly across its edge yields a long crescendo from silence to thunder; two timpani sticks give a delicate rhythmic figure; a wire brush, almost an exhalation. It is the cymbal of Rimsky-Korsakov’s Scheherazade and of every impressionist score since.

“The cymbals reinforce the orchestra most happily in passages of a joyous, brilliant, or pompous character.”

— Hector Berlioz, Treatise on Instrumentation (paraphrased)

The instrument is forgiving of conviction and unforgiving of habit. Write a single crash where the music demands one, a single roll where it asks for weather, and the cymbals will do the rest.
