This piece is a characteristic salon-style Choro featuring an expressive, vocal-like melody. It emphasizes the romantic and emotive side of the genre rather than the high-tempo virtuosity.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: a true singing tone, with the melody floating above the accompaniment; a left hand with real melodic or rhythmic responsibility of its own; and chord voicing — bringing out one note inside a handful of others.
Students must pay close attention to the expressive phrasing and the balance between the melodic lines.

You should be comfortable at Henle level 4 — meaning you can already play level 3–4 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
