These three volumes are a summary by the renowned author and performer of his pioneering efforts and many years of experience as lecturer and teacher of this historical brass instrument at the Schola Cantorum Basiliensis. Though conceived mainly for players of Baroque or natural trumpets, they are also essential reading for players of modern valve instruments who aim for an enlightened approach to Baroque performance practice. The varied exercises and pieces, some taken from 19th-century methods, add up to a systematic course of tuition helping to solve all technical and musical problems, particularly those connected with ensemble playing.
