Although Ravel wrote fewer than thirty works for the piano, they exemplify his range; Orenstein remarks that the composer keeps his personal touch "from the striking simplicity of "Ma mère l'Oye" to the transcendental virtuosity of "Gaspard de la nuit"". Ravel's earliest major work for piano, "Jeux d'eau" (1901), is frequently cited as evidence that he evolved his style independently of Debussy, whose major works for piano all came later. When writing for solo piano, Ravel rarely aimed at the intimate chamber effect characteristic of Debussy, but sought a Lisztian virtuosity. The authors of "The Record Guide" consider that works such as "Gaspard de la Nuit" and "Miroirs" have a beauty and originality with a deeper inspiration "in the harmonic and melodic genius of Ravel himself".
