Ysaÿe is the both a performer and composer. Although there has never been short of such multifaceted musician in the musical history, Ysaÿe's contribution to the repertory of unaccompanied violin works both combines the violinistic technique and musical content better and opens up more possibilities to the development of unaccompanied violin works. His contribution is not only limited to the work itself but his performing style also sets an example for violinists of later generations. He used the technique of vibrato to enhance the strength of sound and variability of tension, and his principles of using rubato endows performers a more reasonable and balanced interpretation.

This supporting document focuses on Ysaÿe's Sonata No.3 entitled "Ballade" from his Six Sonatas for Solo Violin, Op.27, dedicated to violinist Georges Enesco (1881-1955). The sonata is highly varied in musical content and is full of technical development. The methods of this study is threefold: research and analysis from the compositional techniques and materials, from the interpretive insights of performers and from Ysaÿe's unique use of rubato, in the hope of obtaining different inspirations and an interpretation more in depth.
