This book is an introduction to the art of piano tuning, a handy and interesting skill to have. You can use this skill to make pocket money, or a full-time income. However, to be a bad piano tuner is a sacrilege. As professionals we strive to not only be good at what we do, but educate the public as well. To tune a piano poorly in order to make "a quick buck" is not only cheating the customer out of their money, but also robbing them of the experience of having a properly tuned instrument. This can cause students to lose interest, owners to lose trust, and fellow tuners to lose respect. To be a Professional Piano Tuner, you must strive to be as skilled, honest, and informative as possible. Included in this volume is an overview of how music itself works - a guide to going about learning enough about music so that it can add to the skill set needed to be a good piano tuner! Among the topics covered in this book are: The Mechanics of Tuning Hammer Technique The Temperment The Keyboard Intervals Temperment Patterns The Harmonic Sequence The Stretch Octave Tuning Unison Tuning Pitch Raising and Lowering Keyboard Technique Learning Music as a Second Language Keyboard Training Exercises Ear Training What is Perfect Pitch?
