The Piano Concerto No. 20
in D minor, K. 466, was written by Wolfgang Amadeus
Mozart in 1785. The first performance was at the
Mehlgrube Casino in Vienna on February 11, 1785, with
the composer as the soloist.
A few days after the first performance, the composer's
father, Leopold, visiting in Vienna, wrote to his
daughter Nannerl about her brother's recent success: [I
heard] an excellent new piano concerto by Wolfgang, on
which the copyist was still at work when we got there,
and your brother didn't even have time to play through
the rondo because he had to oversee the copying
operation.
It is written in the key of D minor. Other works in that
key include the Requiem, a Kyrie, and the dark opera Don
Giovanni. It is the first of two concertos written in a
minor key (No. 24 being the other).
The young Ludwig van Beethoven admired this concerto and
kept it in his repertoire. Cadenzas for this popular
concerto written by famous composers include Beethoven,
Johannes Brahms, Johann Nepomuk Hummel, Feruccio Busoni
and Clara Schumann.

The Piano Concerto
No. 23 in A major (K. 488) is a musical composition written by
Wolfgang Amadeus Mozart. It was finished, according to Mozart's
own catalogue, on March 2, 1786, around the time of the premiere
of his opera, The Marriage of Figaro. It was one of three
subscription concerts given that spring and was probably played
by Mozart himself at one of these. The concerto is scored for
flute, two clarinets, two bassoons, two horns and strings. Source/Quelle:

The
Symphony No. 4 in D major, K. 19, by Wolfgang Amadeus
Mozart was composed in London during the Mozart
familiy's Grand Tour of Europe in 1765, when Mozart was
9 years old.
Even though the original of Mozart's manuscript has not
survived, the set of parts written in the hand of his
father, Leopold Mozart, is preserved in the Bayerische
Staatsbibliothek in Munich. It is known today that the
early symphonies by young Mozart were performed at the
public concerts in the Little Haymarket Theatre in
London. It is therefore possible that these parts were
written for one of these public performances.
The work is scored for two oboes, two horns and strings.
There are three movements, as was standard in the early
classical music era in which the child Mozart wrote, in
the typical fast-slow-fast configuration. Source/Quelle:
