Alerta! by Fonseca Costa is an obscure 19th-century salon march characterized by its crisp, rhythmic character. It represents the lively tradition of Brazilian piano music during the early transition to nationalistic styles.
Maintain a consistent, energetic rhythmic drive while ensuring the detached articulations remain clear and even.
Comparable difficulty and character — good candidates for what to learn next.
Alerta! is rated Henle level 3 of 9 — late beginner repertoire, roughly ABRSM grades 4–5. In the RCM system it corresponds to about level 4.
You should be comfortable at Henle level 3 — meaning you can already play level 2–3 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 Alerta! lasts about 3 minutes.
Alerta! is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
