For the first time, Weissenborn’s Method and both volumes of his Opus 8 Studies are presented in one book, revised and expanded by noted bassoonist and teacher Frank Morelli. This edition includes Ludwig Milde’s Scale and Chord Studies, a new and innovative Study Key, and additional lessons that introduce all notes beyond high Bb to high E. The book offers comprehensive, basic, and advanced pedagogical instruction from Julius Weissenborn as well as Frank Morelli through various studies, methods, and techniques. With thirty-six newly added duets based upon popular themes and many important orchestral bassoon solos, fingering charts, and a revised and expanded glossary, this is a truly complete landmark volume.
