full_question: Just before the recapitulation of the first movement of a work in this form by this composer, the principal theme in C major gives way to an E major folk dance, then an E minor variation, before returning to the original C major theme. Another of these compositions features a third movement in which the trio is replaced by an "alternativo" consisting almost entirely of E-flat major scales. One of these works by this composer contains a D-minor third movement in the form of a two-part canon called the "Witches' Minuet" and gets its nickname from the opening A-D, E-A sequence in its first movement. The first movement of another of these pieces opens with a theme that comprises the notes G-E-F-D-C, a musical acronym for "Gott Erhalte Franz Den Kaiser," a piece by its composer that it also quotes. Pieces in this genre nicknamed "Fifths" and "Emperor" appear in a collection of them named for their composer's patron Count von Erdödy. The nicknames "Sun" and "Russian" are given to other collections of, for 10 points, what type of chamber piece composed by an Austrian known as their "Father"?
