Schubert's '5 Ecossaises,' D.697, are delightful, short character pieces in the style of a Scottish dance. They showcase his gift for melody and his ability to create varied moods within concise forms.
Pay close attention to the subtle harmonic shifts and the lilting rhythm of the ecossaise.
5 Ecossaises (D.697) 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.
