Preludes Nos. 5-10 were composed between 1930 and 1951, and published the following year, in 1952, by Salabert as Six Preludes.

This Prelude No. 6 was written in 1930. It is unique among the preludes in that it is written for the left hand. Moderato – Cantabile espressivo. Overall, it is written in a form where the opening motif develops. There is no time signature or key signature. No bar lines are written at all, requiring ample rubato from the performer. Once the structure of the piece is understood, the challenge lies in how to bring out the resonance of each individual note. It requires concentration and a delicate ear in terms of touch, phrasing, and pedaling. It is a sad yet beautiful piece that resonates deep within the heart.
