The Complete Scale Compendium The mastery of scales and scale patterns has long been established as the best way to improve technical abilities on all instruments. The Complete Scale Compendium focuses on what is most common in the study of classical music: core major and minor scales, as well as chromatic, pentatonic, whole-tone, and blues scales. Students will learn the construction of these scales while practicing unique patterns, enriching their technique. Specific slurs and articulations have been left off of the exercises so that a multitude of different articulation and slur patterns can be used. The exercises are presented in two ways: by scale pattern and by key.
