I've an unknown edition of the sheet of Ida Presti's 6 Etudes (the one marked "Photocopie Interdite... 11 Mars 1957"). It seems to have some errors in both the notes and the fingering. However Ida Presti enjoys both the occasional use of discords and jumps in the fingering, therefore one has to be careful. I'm currently looking at Étude #6 (Allegretto in Am). If anyone is familiar with it I would welcome comments on measure 22. The sheet and the Yoram Zerbib recording both have B,F,D,A for the main beats of the measure, but before committing myself to it, I wondered if there are any editions with B,F#,D#,A (which is easier on the ear). Alternatively, can anyone point me to an Ida Presti recording of this piece? Thanks.
