This 'Andenken' (Remembrance) by Schubert, D.99, is a shorter, more intimate piece. It likely offers a sweet and reflective mood, characteristic of Schubert's smaller-scale piano works.
The focus here is on creating a clear and beautiful melodic line with subtle harmonic color.
Andenken (D.99) is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 8.
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 Andenken (D.99) lasts about 4 minutes.
