Christoph Martin Wieland (] ; 5 September 1733 – 20 January 1813) was a German poet and writer.
 He is best-remembered for having written the first Bildungsroman ("Geschichte des Agathon"), as well as the epic "Oberon", which formed the basis for Carl Maria von Weber's opera of the same name.
Carl Maria von Weber's Concerto for Bassoon in F Major, Op. 75 (J. 127) was composed in 1811 for Munich court musician Georg Friedrich Brandt, and then revised in 1822.
 Primarily an opera conductor and composer, Weber had only arrived a few months earlier in Munich, where he was extremely well received.
 The concerto is one of two pieces written for bassoon by Weber, the other being "Andante e Rondo Ungarese", Op. 35 (J. 158).
 A typical performance lasts 18–20 minutes.

 The libretto, by , is a reworking of an earlier, unsuccessful opera by Weber, "Das Waldmädchen ".
 Weber also reused music from the same piece in "Silvana".
Oberon is a king of the fairies in medieval and Renaissance literature.
 He is best known as a character in William Shakespeare's play "A Midsummer Night's Dream", in which he is Consort to Titania, Queen of the Fairies.
"Peter und Ännchen" premiered on 29 September 1809 in the theatre of the Ludwigsburg Palace near Stuttgart.
 The opera was popular in Germany in its day and a version of the score for voice and piano was published by Breitkopf & Härtel.
 It was also performed in Paris in 1810 as "Pierre et Annette".
 Franz Carl Hiemer had written the libretto for Abeille's first opera, "Amor und Psyche" (1800) as well as the libretti for Carl Maria von Weber's operas "Silvana" and "Abu Hassan".
Amor und Psyche is an opera ("singspiel") in four acts composed by Ludwig Abeille to a German "libretto" by Franz Carl Hiemer (1768–1822).
 Based on the story of Cupid and Psyche, the opera premiered on January 18, 1800 at the Hoftheater (Herzöglichestheater) in Stuttgart.
 "Amor und Psyche" was popular in Germany in its day and a version of the score for voice and piano was published by Breitkopf & Härtel.
 Franz Carl Hiemer went on to write the libretto for Abeille's third opera, "Peter und Ännchen" (1809) as well as the libretti for Carl Maria von Weber's operas "Silvana" and "Abu Hassan".
Euryanthe is a German "grand, heroic, romantic" opera by Carl Maria von Weber, first performed at the Theater am Kärntnertor, Vienna on 25 October 1823.
 Though acknowledged as one of Weber's most important operas, the work is rarely staged because of the weak libretto by Helmina von Chézy (who, incidentally, was also the author of the failed play "Rosamunde", for which Franz Schubert wrote music).
 "Euryanthe" is based on the 13th-century romance ""L'Histoire du très-noble et chevalereux prince Gérard, comte de Nevers et la très-virtueuse et très chaste princesse Euriant de Savoye, sa mye.""
Die drei Pintos ("The Three Pintos") is a comic opera of which Carl Maria von Weber began composing the music, working on a libretto by Theodor Hell.
 The work was completed about 65 years after Weber's death by Gustav Mahler.

Carl Maria von Weber's Symphony No. 1 in C was written in 1806–1807.
 While not usually acknowledged as among Weber's greatest works (a fact readily admitted by Weber himself), it is a testament to the young composer's gift of melody.
