You can teach yourself accordion

A comprehensive method written especially for serious students learning the accordion without access to formal music lessons. Seasoned music educator and performer Neil Griffin guides the student through music reading fundamentals, correct posture and hand positions, use of the bellows, bass buttons, keyboard, and more. Music theory concepts are introduced as required by the generous selection of carefully graded exercises and pieces. Although this book covers concepts that apply to the 120-bass accordion, it only uses 54 buttons (covering 9 rows in easy keys). Illustrated with diagrams and photographs. Includes access to online audio.
