 -The Piano Concerto No.1, K.37 in F major, Mozart- The Piano concerto was written by Wolfgang Amadeus Mozart. When W.A. Mozart was at 11 year in Salzburg, he began his four series of preserved Piano concertos.  The autographs of this music were held in Jagiellonian Library, and they were dated in April in 1767 by his father.  Traditionally, these works were long considered to be his original works, but they are now known to be participating of sonatas by various composers. The structure The concerto in F major is composed of two oboes, two horns, Piano (or cembalo), strings. Also, the three movements are in 3 1.Allegro (4/4) 2.Andante in C major (3/4) 3. Allegro (3/4) The first movement is based on first Allegro of the keyboard sonata, Op.1, No.5 that was published by H.F.Raupach in Paris, 1756. The second movement was originally written by Mozart. Finally, third movement is based on first movement of Sonata, Op.2, No.3 by Leontzi Hohauer. Link:  The Piano Concerto ...

 -The Quartet No.20 in D major, K.499, Mozart- The Quartet was written by Wolfgang Amadeus Mozart in Vienna in 1786. This piece was published by his friend - Franz Anton Hoffmeister.  Because of this reason, the Quartet has named the nickname Hoffmeister. The structure Thete are four movements. 1. Allegretto in D major 2. Menuetto in D major with a trio section 3. Adagio in G major 4. Allegro in D major This work is between the six quarters of Haydn (1782~1785) and the following three Prussian Quartet, and it is often used to a polyphonic way that is uncharactered in the earlier part of the classical music era.  The menu ethos and trio section show these examples, with irregular Canon between the first violin and viola, and double imitation in the trio between the violins, viola, and cello.
