In addition to being an outstanding musician, Arnold Jacobs undoubtedly was the most influential brass teacher of the second half of the twentieth century. Countless brass (and other) musicians from all over the world travelled to Chicago to study with this master. Additionally, Mr. Jacobs also gave master classes that were popular with students, teachers and professionals in many different locations. Even if it were all known, it would be impossible to reduce to writing all of the advice Arnold Jacobs gave to thousands of students over a period of almost 70 years. Nevertheless, this book is an attempt to preserve in writing, by topic, the common ideas and variations of those ideas from which so many musicians have benefited. ISBN 978-3-9812456-2-2
