In music, an ostinato [ostiˈnaːto] (derived from Italian: stubborn, compare English: 'obstinate') is a motif or phrase that persistently repeats in the same musical voice, usually at the same pitch. The best-known ostinato-based piece may be Ravel's Boléro or Giorgio Moroder's I Feel Love.The repeating idea may be a rhythmic pattern, part of a tune, or a complete melody in itself. Both ostinatos and ostinati are accepted English plural forms, the latter reflecting the word's Italian etymology.
