🇮🇹Ferruccio Busoni ： Improvisation on the Bach Chorale Glücklich ist

Based on the Bach chorale “Glücklich ist,” this piano-duet work expands the chorale through Busoni’s improvisatory imagination. Using the familiar chorale melody as its point of departure, it brings together the poise of the original and a sense of free development, creating added depth through the dialogue between the two performers. A central point of interest is the contrast between passages in which the chorale line is clearly presented and those in which the accompaniment and register shift to alter the character. The melodic voices should be carefully brought to the fore, while the players coordinate pedaling and dynamics and maintain the flow through shared breathing. It is a piece that calls for both improvisatory freedom and the precision of ensemble playing.
