The author, Alan Si, has enjoyed a career both as a performing musician & as a research engineer. His study of clarinet fingerings has led to this book which should be of value to students, to performers, & to the simply curious! It is an organized collection of 303 fingerings for 52 chromatic notes rising to the altississimo G two octaves above the stave! These are supported by 276 fingerings for half & whole-tone trills.
