Henri Büsser's Asturias is a lyrical work that draws on Spanish-inflected harmonic language. It requires a refined touch to balance the melodic lines against rich, rolling arpeggios.
Use careful pedaling to connect the broad arpeggiated figures without muddying the harmonic shifts.
Comparable difficulty and character — good candidates for what to learn next.
Asturias (Op.84) 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 Asturias (Op.84) lasts about 5 minutes.
