Zelo

What it means

Zelo means “zeal” and appears as a performance instruction mostly in the phrase con zelo, “with zeal”. What is called for is an engaged, eager performance that proceeds with palpable commitment.

The marking is rare in notated text and belongs among those Italian words that individual composers use without a fixed tradition having formed. Its meaning is worked out from the word itself and from the context.

Con zelo differs from con brio, which means verve and fire, through its overtone of earnestness: zeal is purposeful and serious, not exuberant. It differs from animato, which calls for animation, through its emphasis on commitment rather than on liveliness. It differs from energico in that devotion is meant rather than force.

In the notation

The word stands in italics above the staff, mostly in the phrase con zelo after a tempo word, and holds until a new marking.

Musical use

The marking is used in animated sections that are to be driven forward with emphasis, for instance in developments or in passages in which several voices chase one another. It is rare and therefore, where it stands, works as a special hint from the composer.

The instruction, mostly as con zelo, calls for an eager, committed performance with energy and devotion. It is rare and stands above all in nineteenth-century Italian scores. The character is lively and vigorous, similar to con fuoco or con brio, but less violent. It needs clear articulation and a forward-pressing

Performance practice

Look for zeal in clear articulation and a pulse with a forward pull. Keep the tempo stable nonetheless, so that zeal does not tip over into haste. Work out the motives distinctly. And keep reserve in the dynamics for the passages where the commitment intensifies.
