Ritenuto

Ritenuto, abbreviated riten., is sometimes confused with ritardando, but the markings have distinct technical meanings. Ritardando is a gradual slowing across a passage. Ritenuto is an immediate slowing — the music is held back from one moment to the next, often for just a beat or a measure.

The distinction matters in performance. A ritardando affects the overall arc of a passage; a ritenuto creates a sudden tug of restraint, as if the music has paused to gather itself. Composers use ritenuto for momentary expressive emphasis — a single beat dragged slightly to underline a harmony, a chord, a word in a vocal line.

In practice, however, the distinction is often blurred. Many editors and performers treat ritenuto as essentially equivalent to ritardando, especially in older scores where the terminology was less precise.

Italian, past participle of ritenere (‘to hold back, retain’), from Latin retinere.

If the score is clearly modern, distinguish ritenuto (sudden, momentary holding back) from ritardando (gradual slowing across a passage). In older scores, accept the ambiguity and let context decide.
