name the three compositional style periods of stravinksy
Igor Stravinsky Stravinsky's output is typically divided into three general style periods: a Russian period, a neoclassical period, and a serial period.
Rondo In rondo form, a principal theme (sometimes called the "refrain") alternates with one or more contrasting themes, generally called "episodes", but also occasionally referred to as "digressions" or "couplets". Possible patterns in the Classical period include: ABA, ABACA, or ABACABA.[6] These are sometimes designated "first rondo", "second rondo", and "third rondo", respectively. The first rondo is distinguished from the three-part song form principally by the fact that at least one of the themes is a song form in itself, but the difference in melodic and rhythmic content of the themes in the rondo form is usually greater than in the song form, and the accompanimental figuration in the parts of the rondo (unlike the song form) is usually contrasted.[7] The number of themes can vary from piece to piece, and the recurring element is sometimes embellished and/or shortened in order to provide for variation.
