Roberto Gerhard's 'Alegrías' is a complex, modern work that integrates Spanish folk elements with atonal structures. It is known for its intense rhythmic drive and sudden shifts in mood.
The integration of conflicting rhythmic groupings requires careful counting and coordination.
Comparable difficulty and character — good candidates for what to learn next.
Alegrías 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 Alegrías lasts about 5 minutes.
Alegrías is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
