note: while I use contemporary examples to formulate my question, I'm asking for answers based on examples in classical music.
Two contemporary music examples of a "mashup", the combination or even superposition of two unrelated musical works that highlights their unexpected compatibility and/or similarity can be heard in the following examples in YouTube:
- Michael Jackson, Lil Nas X & Jack Harlow - Industry Baby (Beat It)
- Lil Nas X ft. Michael Jackson - Industry Baby X Beat It (Mashup)
(while the visual parts of the links can serve to better identify when the two works are interposed, they are not necessary to watch for the purposes of this question; one can simply listen if contemporary music videos are not one's cup of tea)
Question: Are there any examples in classical music history of "mashups" of two unrelated works?
These might be a third work combining elements of two (or more) previous works, or a second work paying "homage" to a previous work.
They might be serious examples, or a bit of musical humor by the classical period composer. I specify that because there are no doubt *classical-sounding( examples of the P.D.Q. Bach variety.
