A brindisi (pronounced [ˈbrindizi]; Italian for "toast") is a song in which a company is exhorted to drink, a drinking song.
The word is Italian, but it derives from an old German phrase, (ich) bringe dir's – "(I) offer it to you", which at one time was used to introduce a toast. The transformation of that phrase into the current Italian word may have been influenced by similar-sounding name of the Italian city of Brindisi, but otherwise the city and the term are etymologically unrelated.
The term brindisi is often used in opera. Typically, in an operatic brindisi, one character introduces a toast with a solo melody and the full ensemble later joins in the refrain.
