"Prokofiev’s playing of lyrical music is especially noteworthy. His phrasing can be exquisitely beautiful in its dynamic molding , and his polyphonic voicing can be clear and expressive ."

“In spite of the many valuable books available today, the state of Prokofiev scholarship cannot be considered adequate: suffice it to say that the detailed catalogue of his works has not been updated since it was published in 1961. At present, there is no edition of the Prokofiev sonatas free of errors. I have tried to do my best in pointing out some obvious mistakes, as well as certain doubtful readings. Many questions cannot be answered with certainty, as the manuscripts for some of the sonatas have been lost; those that have survived are not easily available for inspection. To get to some of them, I was fortunate to have the help of Russian colleagues in overcoming the restrictions of the current gatekeepers in Russia.”

“Prokofiev’s creative path traversed many countries and was affected by wars and revolutions. Life brought him into contact with some of the most prominent and influential artistic figures of his time. Observing the magnificent panorama of Prokofiev’s oeuvre, one sees that the composer’s musical style evolved significantly over the course of his creative life. The reasons for the changes of direction have been much discussed and debated.”

“One of the most winning characteristics of Prokofiev’s music is its indomitable energy. In expressing this quality, stability of tempo is particularly important.”

“Many pages of Prokofiev’s oeuvre continue the important tradition of Russian music based on fairy tale–inspired imagery.”

“Prokofiev’s music is usually based on a firm sense of tonality. Whatever tonal uncertainty and ambiguity one experiences, mainly in developmental passages, they are mostly short-lived.”

“Prokofiev had a lifelong love of the sonata form. Ever since learning the basic rules during his childhood years, he strove to master them; … In 1941, describing his Sonatinas op. 54 , he remarked, “I liked the idea of writing a simple work in such a superior form as sonata.” One can learn a lot about the composer’s growth by tracing his progress from the early sonatas, which cautiously dare to bend the textbook rules, to the masterful treatment of the form in his late works.”
