April Fool's Day is a day when people participate in pranks and play practical jokes on others. History.com says it was first popularized as a holiday in the year 1700.
Peter Schickele is an American musician and composer born in 1935 who is also known as P.D.Q. Bach. He has played practical jokes on the musical world by performing music he says he "discovered." He loves satire and parody, and many of his pieces and performances are quite hilarious, especially if you know the "real" music quite well.
Wikipedia says this:
"The humor in P. D. Q. Bach music often derives from violation of audience expectations, such as repeating a tune more than the usual number of times, resolving a musical chord later than usual or not at all, unusual key changes, excessive dissonance, or sudden switches from high art to low art. Further humor is obtained by replacing parts of certain classical pieces with similar common songs, such as the opening of Brahms' Symphony No. 2 with "Beautiful Dreamer", or rewriting Tchaikovsky's 1812 Overture as the 1712 Overture, with "Yankee Doodle" replacing Tchaikovsky's melody, and "Pop Goes the Weasel" replacing "La Marseillaise"."
Let's listen to some funny performances by P.D.Q. Bach as we celebrate April Fool's Day.
