Based on an article written in 1923 by legendary Russian pianist and composer Sergei Rachmaninoff (1873-1943), this volume presents the series of chords, arpeggios, and scales that Rachmaninoff himself studied as a young man. The Preface contains a short history explaining Rachmaninoff’s use of this exercise and demonstrates that similar studies were included in some of the earliest keyboard methods dating to the eighteenth century. More than finger exercises, these patterns encourage harmonic thinking and reflect the modern approach to piano technique with its emphasis on engaged practice. Having its roots in the earliest history of keyboard pedagogy, and practiced and promoted by Sergei Rachmaninoff, Josef Lhèvinne, Franz Liszt, and other legendary pianists, the exercises in this volume are a true link to the Golden Age of piano performance. Without question, diligent study will greatly improve every dedicated student’s musicianship and technique.
