An Introduction to Warm-Ups, Blocking, and Playing Aloys Schmitt and Charles-Louis Hanon, Edited by Tom Gerou This edition serves as an introduction to playing scales and arpeggios in an easy-to-read format. Preliminary exercises prepare the hand for finger crossings and stretches and are selected from Preparatory Exercises, Opus 16 by Aloys Schmitt and The Virtuoso Pianist, Book 2 by Charles-Louis Hanon. These exercises allow the opportunity to properly develop form and technique. Exercises found in Units 1 and 2 may be transposed to other keys as necessary. This edition excludes exercises that require stretches beyond the developmental capabilities of students with small hands.
