José Vianna da Motta, a student of Liszt, brings a distinct European late-Romantic aesthetic to this ballade. It is characterized by refined chromaticism and an intimate, introspective narrative tone.
The performer must master the art of subtle voicing within the complex, chromatic inner-voice movements.
Comparable difficulty and character — good candidates for what to learn next.

You should be comfortable at Henle level 6 — meaning you can already play level 5–6 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 Ballada (Op. 16) lasts about 5 minutes.
Ballada (Op. 16) is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
