In the quasi-exotic exercises by Tortelier, we explore the "Marathon anti-Routine," which, similar to Cossmann velocity studies, works on crisp, clean left finger articulation. We also find ways to increase speed while decreasing tension.

In the lesson on vibrato by Paul Bazelaire, we study the independence of the hands. We learn why it is so important for the left hand to be independent of the right, and we learn how to vibrate in a big way, regardless of volume.

In the Michel Simmönsian vibrato exercise, we study the art of continuous vibrato. One of the most important aspects of string playing, Lelchuk puts special emphasis on the art of continuous vibrato and how we can learn to control all our fingers and hand oscillations so we can produce long, singing lines.

In this lesson, we get a summary of the basic question: why is it so important to practice this book every day? We learn that repetition builds muscle memory and that when we build our foundation solidly, we will learn the repertoire we dream of playing faster and more thoroughly than we ever thought possible.
