Mozart rondo alla turca
Mozart wrote well over 1000 pieces of music. My personal favourites, though, are his Oboe Concerto in C Major K 314, Rondo Alla Turca K 331, Queen of the Night from Die Zauberflöte and Symphony No. 40.
The Rondo Alla Turca comes from Mozart's Piano Sonata No. 11. Mozart was a composer during the Classical Period. Therefore Alla Turca is classical and not baroque.
Mozart's Rondo Alla Turca but played in the keys of G minor and C major.
Mozart's Symphony Number 41, K. 551, is in C major, not C minor, and it is called "The Jupiter Symphony," though Mozart himself did not give it any title.
Wolfgang Amadeus Mozart composed the "Rondo Alla Turca" (Piano Sonata No. 11 in A major, K. 331) when he was around 27 years old. The piece was written in 1783, during a prolific period of his career. It features a lively and catchy theme that has become one of his most famous works.
The rondo form introduced in classical period is not to be confused with the renaissance rondo. It is also known as ABACADA form. The principal theme 'A' restates after each episode (B C and D as here). A popular example is Mozart's Marcia alla Turka from his piano sonata, K 331.
It dates as far back as the 18th century, ex. Mozart's Rondo in A Minor for piano, K 511 (1787).
Yes, Rondo Allla Turca is in the key of A minor.
It can be. Mozart wrote lots, but so did some more modern composers.
It's the 3rd movement of his A major piano sonata. In Austria people call it "Türkischer Marsch" (turkish march), but I don't really know why that is.
