I’m trying to order “Quarante etudes faciles” by N.C. Bochsa, and Lyon & Healy has it, but it’s by R.N.C. Bochsa. I don’t know if it’s the same and I have been trying to find this book, because it is needed in the new harp syllabus.
Yes, it’s at Lyon and Healy West and also at Lyra Music in the U.S., and at Pilgrim Harps in the U.K. Be sure it’s 40 studies, Opus 318. He has a collection of 50 studies that are not the same. The edition by Oberthur is in one volume. The one edited by Hasselmans is split into two, with 20 studies in each.
