Mozart (born January 27, 1756): Violin Concerto No. 5 in A major, mvt. 3 Rondeau--tempo di menuetto
We have already learned about cadenzas, and about rondos. You will hear both in this movement, which features a special kind of cadenza called an "eingang" (German for "entrance"). As you remember, rondos have the form "ABACADA..." The eingang happens at the end of each interlude and leads us back into the familiar "A" theme. Eingänge are usually short, with just a bit of filler material, but in this performance they are much more elaborate than they probably would have been back then! (During Mozart’s time, cadenzas were generally not written down by the composer, and they were often improvised. Here, the soloist has written the cadenzas, but is not improvising for the most part.)
This concerto has been nicknamed the "Turkish" concerto, because of the dramatically contrasting middle section, which switches from a major to a minor key, and from triple to duple meter--i.e. it is counted in two, unlike the rest of the movement which is counted in three. It is thought to have an exotic, Turkish flavor to it.
