ViolinMind is a pedagogical method book that focuses on intonation. It is a transcription for the violin of CelloMind published in 2017 by Ovation Press, Ltd. The co-authors of ViolinMind are Hans Jørgen Jensen, Professor of Cello at the Bienen School of Music at Northwestern University and Grigory Kalinovsky, Professor of Music (Violin) at Indiana University Jacobs School of Music. The mystery of intonation is dissected by defining the scientific principles behind it, and providing easy, intuitive examples of the three main kinds of intonation systems used today: Equal Temperament, Just, and Pythagorean. Playing with exquisite intonation has mostly been reserved for those who possess a strong intuitive sense of pitch and harmonic color; however, ViolinMind breaks down this barrier using a highly detailed, systematic approach, making the process of acquiring a sophisticated sense of intonation similar to any other technical skill. Chapters in the book explore in great detail topics such as the harmonic overtone series, the scientific principles behind Cents, the syntonic comma, the just scales, the Pythagorean comma, the Pythagorean semitones, advanced sympathetic vibrations, Tartini tones, and double stops studies in tritones. All chapters in the book include numerous practical samples and listening exercises that bridge the gap between the theory and its application. The chapters on intonation conclude with practical examples from the following repertoire: intonation performance practice in the Bach Sonatas and Partitas for Violin Solo (BWV 1001-1006), and intonation performance practice with piano. The appendices in the book provide detailed explanations about the Helmholtz intonation chart, the harmonic series, just intonation, the Schisma, as well as an illustration of two violin fingerboards from two method books from the 18th century showing pitch distribution for just intonation and Pythagorean intonation respectively.
