Heitor Villa-Lobos's 'Chôros bis' (W227) is a sophisticated work for piano that integrates Brazilian folk rhythms with modern harmonic language. It is distinguished by its driving energy, complex syncopation, and virtuosic demands.
The primary challenge is maintaining rhythmic precision and clarity while navigating the dense, percussive textures.
2 Chôros bis is rated Henle level 7 of 9 — late advanced repertoire, roughly ABRSM grade 8 and above. In the RCM system it corresponds to about level 9.
You should be comfortable at Henle level 7 — meaning you can already play level 6–7 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 2 Chôros bis lasts about 5 minutes.
