Cavatina

Cavatina (Italian for "little song") is a musical term, originally meaning a short song of simple character, without a second strain or any repetition of the air. It is now frequently applied to any simple, melodious air, as distinguished from brilliant arias or recitatives, many of which are part of a larger movement or scena in oratorio or opera. "Ecco, ridente in cielo" from Gioachino Rossini's opera The Barber of Seville, "Porgi amor" and "Se vuol ballare" from Mozart's The Marriage of Figaro are well-known cavatinas. A famous piece that bears the name, although without words, is the 5th movement of Beethoven's String Quartet in B-flat major, Opus 130.
