Joachim Raff's "2 Études mélodiques" Op. 130 are charming and lyrical works. They prioritize expressive melody and refined phrasing over overt virtuosity, making them delightful studies in musicality.
Focus on shaping the melodic lines with a singing tone and careful use of the pedal.
2 Études mélodiques (Op.130) is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7.
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.
