Michael Mulcahy, of the Chicago Symphony Orchestra, has edited and annotated this edition of the "Melodious Etudes" for trombone.
In addition to the complete collection (all 120) of Bordogni's Vocalises, Mr. Mulcahy has added extensive text covering interpretation, style, natural and tongued legato and many other important topics.
Clear, error-free notation, some advanced studies in tenor and alto clef, and several complete interpretations by Mr. Mulcahy, make this book the premier edition.
