I have become quite interested in Marie Jaell's work 'Pieces Pour Piano', and I'm wondering if anyone can shed some light on the difficulty of the individual 18 pieces of this work. I am most familiar with the ABRSM (ARSM, LRSM, and FRSM) and Henle difficulty rankings. I am currently looking for some future repertoire, and a few of the 18 pieces might be an interesting challenge to take on.
