These studies are intended as practice material for advanced students of the recorder. The first ten studies utilise the generally accepted normal compass of the treble (alto) recorder and are designed to improve the basic techniques of breath control fingering and articulation; the remainder concentrate on specific aspects of 'avant-garde' technique as used in many recent recorder compositions. The edition is part of the Trinity College London syllabus 2015-2016 (grades 5 - 8)
