This work by Israeli composer Rami Bar-Niv explores the cadenza as a standalone expressive form. It is distinct for its improvisatory flair and modern harmonic language typical of the composer's concert style.
The performer must maintain rhythmic control and clarity throughout the virtuosic, improvisatory runs.
Comparable difficulty and character — good candidates for what to learn next.
Cadenza is rated Henle level 6 of 9 — advanced repertoire, roughly ABRSM grades 7–8.
You should be comfortable at Henle level 6 — meaning you can already play level 5–6 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 Cadenza lasts about 4 minutes.
Cadenza is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
