Performer: Frank Peter Zimmermann 　　Composer: Eugene Ysaÿe　　 　　About the composer: 　　Eugène Ysaÿe (16 July 1858 – 12 May 1931) was a Belgian violinist, composer and conductor. He was regarded as "The King of the Violin", or, as Nathan Milstein put it, the "tsar". 　　Born in Liège, Ysaÿe began violin lessons at age five with his father. He would later recognize his father's teaching as the foundation of everything he knew on his instrument, even though he went on to study with highly reputed masters. At seven he entered the Conservatoire at Liège studying with Désiré Heynberg 1865-1869, though soon afterwards he was asked to leave the conservatory because of lack of progress. This was because, in order to support his family, young Eugène had to play full-time in two local orchestras, one conducted by his father. Eugène went on playing in these ensembles, though he studied by himself and learned the repertoire of the violin. By the time he was twelve, he was playing so well that one day he was practicing in a cellar when the legendary Henri Vieuxtemps, passing in the street, was so impressed with the sound of his violin that he took an interest in the boy. He arranged for Ysaÿe to be re-admitted to the conservatory studying with Vieuxtemps's assistant, the noted Henryk Wieniawski. Ysaÿe would later also study with Vieuxtemps, and both "master and disciple", as Ysaÿe would call the roles of teacher and pupil, were very fond of each other. In his last years, Vieuxtemps asked Ysaÿe to come to the countryside just to play for him.　　 　　Studying with these teachers meant that he was part of the so-called Franco-Belgian school of violin playing, which dates back to the development of the modern violin bow by François Tourte. Qualities of this "École" included elegance, a full tone with a sense of drawing a "long" bow with no jerks, precise left hand techniques, and bowing using the whole forearm while keeping both the wrist and upper arm quiet (as opposed to Joseph Joachim's German school of wrist bowing and Leopold Auer's Russian concept of using the whole arm.)　　 　　About the work: 　　Eugène Ysaÿe's Six sonatas for solo violin, Op. 27, is a set of sonatas for unaccompanied violin written in July 1923. Each sonata was dedicated to one of Ysaÿe’s contemporary violinists: Joseph Szigeti (No. 1), Jacques Thibaud (No. 2), George Enescu (No. 3), Fritz Kreisler (No. 4), Mathieu Crickboom (No. 5), and Manuel Quiroga (No. 6). 　　After having heard Joseph Szigeti perform Johann Sebastian Bach's sonata for solo violin in G minor, Ysaÿe was inspired to compose violin works that represent the evolution of musical techniques and expressions of his time. As Ysaÿe claimed, "I have played everything from Bach to Debussy, for real art should be international." In this set of sonatas, he used prominent characteristics of early 20th century music, such as whole tone scales, dissonances, and quarter tones. Ysaÿe also employed virtuoso bow and left hand techniques throughout, for he believed that "at the present day the tools of violin mastery, of expression, technique, mechanism, are far more necessary than in days gone by. In fact they are indispensable, if the spirit is to express itself without restraint." Thus, this set of sonatas places high technical demands on its performers. Yet Ysaÿe recurrently warns violinists that they should never forget to play instead of becoming preoccupied with technical elements; a violin master "must be a violinist, a thinker, a poet, a human being, he must have known hope, love, passion and despair, he must have run the gamut of the emotions in order to express them all in his playing."
