The purpose of this article is to provide a mnemonic device that when incorporated into practice behavior is shown through case study to help students develop an understanding of the relationship between exercises, new and old, and the music that they are preparing. I developed the mnemonic "Preparation of Relevant Activities Causes Technical Improvement, and, Correct Execution" and conducted a limited case study with cello students unknown to me prior to the study, and observed the result of this approach in their practice. This article describes the relationship of the three parts of the mnemonic device and how they are applied for the student.
