There are several compositions that I think are funny among them Chopin's Funeral March (opus# 35), Brahms Concerto for Violin and Cello "Double Concerto" (opus # 102), and Tchaikovsky's Andante Cantible for Cello and Orchestra (opus # 11).
The funny thing about Chopin's funeral March is that is used in a lot of funny commercials. It was used in a funny you tube video of reporters and celebrities freaking out because of Trump winning the election. Although I don't want to discuss politics, I liked the vice presidential candidates better. Although this piece is supposed to be serious, the fact that it is used in commercials makes it funny.
The Brahms Double concerto second movement Andante is very poignant. I don't know why but I think that this is funny I did not used to. It was Brahms last orchestral piece.
The Tchaikovsky Andante was originally part of his first string quartet(opus #11)poignant. It is also very beautiful. It was played in the background in an episode of the CBS Radio Mystery theatre "Murder Museum", which originally aired in 1974.
cbsrmt.comThe CBS Radio Mystery Theatre was a radio series on CBS from 1974-1982 which was an attempt to revive old time radio. I liked a lot of their episodes. check out it's web page. It was hosted by E. G. Marshall at first then Tammy Grimes. Marshal played on the early 1960's TV series The Defenders. Grimes is married to Christopher Plumber. As is known, Plumber played as Captain Von Trap in The Sound of Music. He also played in the Movie Delores Claiborne which was based on the Stephen King novel. Mystery theater is available on line. Those who are over 46 may remember this series. anybody born before 1950 remembers old time radio shows.
Brahms and Tchaikovsky were contemporaries. I will talk more about them later. Chopin was older. Chopin wrote mostly for the piano. I am not as familiar with his works as I am with the last two composers. Chopin wrote mainly for solo piano. I do like his Piano Trio (opus #8)
There are a lot of funny rock and roll and popular pieces of music in addition to the novelty songs. There are a lot of novelty songs around Christmas. One song that does crack me up and I don't know why is "Band of Gold" by Freda Payne from 1970.
One anecdote about Schubert's 9th Symphony is that when it was first played in Vienna in 1844, 16 years after Schubert's death the musicians considered it was too funny and cracked up about it! This is one of my favorite symphonies also. I don't think that it is funny.
