Vicente Costa Nogueras composed this piece as a light, sparkling character study reminiscent of the Spanish salon tradition. It effectively utilizes rapid figuration to suggest the effervescence of champagne.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: fast passage work that stays light and even at tempo; precise articulation — the difference between crisp and blurred is the piece; and sweeping arpeggio figures that must stay smooth across positions.
Pay close attention to evenness in the rapid running passages to capture the sparkling character.
