Emil Śmietański’s Ballade serves as a stylistic example of Polish salon music from the turn of the 20th century. It features idiomatic keyboard writing with a focus on deep, expressive resonance.
Achieving independence between the melodic left hand and the harmonic right hand is essential for a clear performance.
Comparable difficulty and character — good candidates for what to learn next.
Ballade 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 Ballade lasts about 4 minutes.
Ballade is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
