Williams The Secret of Technique Preservation

Ernest S. Williams sums up the idea behind this book by saying that “the exercises in this volume were originally put together for my own personal use, when necessity forced me to curtail my practice time even though it was imperative that I keep my skill. The routine became of immeasurable value when I was travelling, or on days when I had to attend a long rehearsal in the morning, make recordings in the afternoon, and play a concert at night.”

Simply put: how to stay in shape when demands are high.
