Transcriptions.
In 1803, Franz Xaver Heinz Klein arranged this piece for viola and piano. It was published as the "Notturno for Viola and Piano in D major", Op. 42, with Beethoven incorrectly credited as its author (although he did make corrections to Franz' work).
In his book "Classic Music: Expression, Form, and Style," Leonard G. Ratner cites the fourth movement as a representative example of the polonaise.
