Body and Soul is a seminal jazz standard by Johnny Green, frequently arranged for solo piano in a lyrical, improvisational style. It is renowned for its sophisticated harmonic progression and deeply emotive melodic arc.
Mastering the thick chordal voicings and subtle rubato is essential for a convincing performance.
Comparable difficulty and character — good candidates for what to learn next.
Body and Soul is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 7.
You should be comfortable at Henle level 5 — meaning you can already play level 4–5 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
A typical performance of Body and Soul lasts about 4 minutes.
Body and Soul is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
