Eronel is a fast-paced bop tune by Thelonious Monk, co-written with Idrees Sulieman and featured on the Blue Note LP Genius of Modern Music: Volume 2. The track was recorded in a historic session that reunited Monk with Art Blakey, Sahib Shihab and Milt Jackson, with Sadik Hakim contributing the bridge. It was released in 1952 as part of the Genius of Modern Music collection, with Al McKibbon on bass. A famous anecdote from Sulieman recounts how Monk played the fourth note as a major seventh instead of the sixth, and kept that interpretation in the final take. Miles Davis once said, it’s not the note you play that’s the wrong note - it’s the note you play afterwards that makes it right or wrong. Eronel showcases Monk’s distinctive piano style within a brisk jazz—bebop context and is a notable piece from Blue Note’s modern jazz era.
