Szigeti also offers a lengthy and detailed explanation of his approach to violin technique. He believed that a violinist should be concerned primarily with musical goals, rather than simply choosing either the easiest or most impressively virtuosic way to play a certain passage. He was particularly concerned with tone color: he advised that "The player should cultivate a seismograph-like sensitivity to brusque changes of tone colour caused by fingerings based on expediency and comfort rather than the composer’s manifest or probable intentions." Other topics prominently discussed include the most effective position of a violinist's left hand, the violin works of Béla Bartók, a cautionary list of widely accepted misprints and editorial inaccuracies in the standard repertoire, and most notably, the vital importance of J.S. Bach's Six Sonatas and Partitas for any violinist's technical and artistic development.
