Piano Quartet (Carmichael)
The term "Piano Quartet (Carmichael)" generally refers to a musical composition written for piano, violin, viola, and cello by a composer named Carmichael. Without further specifying which Carmichael, it could potentially refer to works by several composers with that surname.
Given the relative rarity of notable composers solely known as "Carmichael" in the context of standard classical music repertoire, the term most likely alludes to Hoagy Carmichael, the American composer, pianist, singer, and actor. While best known for his popular songs, it is possible he also composed a piano quartet. However, confirming the existence and details of such a composition requires verification from established musicological resources such as music databases, composer catalogs, or scholarly articles.
If the reference isn't to Hoagy Carmichael, further research is needed to identify which composer is being referenced. There may be lesser-known composers named Carmichael who have written piano quartets. Information such as the composer's first name, birth and death dates, or country of origin would be helpful in disambiguating the reference.
Until further evidence clarifies the specific "Carmichael" in question and confirms the existence and details of a piano quartet attributed to them, this entry remains speculative regarding a definitive composition. Further research into music databases and catalogs is necessary to verify its existence and provide more concrete information regarding instrumentation, movements, and publication history.
