The Piano Sonata No. 16 in C major, K. 545, by Wolfgang Amadeus Mozart was described by Mozart in his own thematic catalogue as "for beginners", and it is sometimes known by the nickname Sonata facile or Sonata semplice. Despite this, the sonata is actually not an easy work to perform and can hardly be described as "for beginners."
Ludwig van Beethoven's Piano Sonata No. 8 in C minor, Op. 13, commonly known as Sonata Pathétique, was written in 1798 when the composer was 27 years old, and was published in 1799. It has remained one of his most celebrated compositions. Beethoven dedicated the work to his friend Prince Karl von Lichnowsky. Although commonly thought to be one of the few works to be named by the composer himself, it was actually named Grande sonate pathétique by the publisher, who was impressed by the sonata's tragic sonorities.
The Piano Sonata No. 12 in F major, K. 332 (300k) by Wolfgang Amadeus Mozart was published in 1784 along with the Piano Sonata No. 10 in C major, K. 330, and Piano Sonata No. 11, K. 331. Mozart wrote these sonatas either while visiting Munich in 1781, or during his first two years in Vienna. Some believe, however that Mozart wrote this and the other sonatas during a summer 1783 visit to Salzburg made for the purpose of introducing his wife, Constanze to his father, Leopold. All three sonatas were published in Vienna in 1784 as Mozart's Op. 6.

Wolfgang Amadeus Mozart began his series of preserved piano concertos with four that he wrote at the age of 11, in Salzburg: K. 37 and 39–41. The autographs, all held by the Jagiellonian Library, Kraków, are dated by his father as having been completed in April and July of 1767. Although these works were long considered to be original, they are now known to be orchestrations of sonatas by various German virtuosi. The works on which the concertos are based were largely published in Paris, and presumably Mozart and his family became acquainted with them or their composers during their visit to Paris in 1763–64.
The Quintet in E♭ major for Piano and Winds, K. 452, was composed by Wolfgang Amadeus Mozart on March 30, 1784 and premiered two days later at the Imperial and Royal National Court Theater in Vienna.
