That book is not that informative. It is mostly about his life. I don’t think it even had a list of works. I was a bit disappointed in it. His music is not too complicated. His background as an organist was informative, I think. He tended to apply color as an organist would use stops, to my ear. His most inventive pieces are the Pastorale, Divertissement, and his very free arrangement of the CPE Bach Sonata and the Children’s Hour. My teacher thought his piece for horn, harp and orchestra was one of his best works. Children at Play is one of his best solos, as is Automne for simpler works. His use of form is much like Tournier’s and Renie’s. His single-movement pieces tend to fall into broad ABA forms with extended cadenzas and figurations. His most modern piece is probably the Children’s Hour Suite. What etudes did he compose? Do you mean the Bach transcriptions? His approach to Bach is romantic, lush chords, flexible dynamics rather than terraced dynamics.
His Fantaisie is apparently much derived from an earlier work by another composer which de Maistre recorded.
His Rhapsodie, to me, is not much different from Renie’s work, except his personality is distinct.
