Written by the 'Mother of Choro', this piece blends European dance forms with the rhythmic sensibilities of Brazilian popular music. It is musically distinctive for its subtle, syncopated inner voices.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: a left hand with real melodic or rhythmic responsibility of its own, and precise articulation — the difference between crisp and blurred is the piece.
The main challenge is maintaining the syncopated, lilt-filled rhythmic feel without distorting the underlying structure.
