tremolando

1. (music) A tremolo section of a piece.Examples: "[…] Mr. Osorio offered Albéniz’s “Suite Española” No. 1 in a reading notable for its high-energy performances of “Granada,” with its lilting melody weaving through guitarlike figuration, and “Asturias,” in which a serpentine theme is wrapped in a hypnotic tremolando figure."; "Wolf's own Wagner paraphrases (c. 1882) often presage the piano parts of his later songs, both in their part-writing and in their transcription of orchestral effects such as string runs or tremolandos."; "The characteristic surface element of the dense tremolandi is immediately projected into the ensemble and conditions all the different means of sound production available, including the unpitched sound of the tam-tam."
