“Here is a handy little reference that can serve a number of purposes. Ricardo Matosinhos, a leading player and teacher in Portugal, compiled this little volume to support the horn player in practice sessionswhen the teacher is not present. As he says, "With the knowledge of the instrument and a better understanding of how it worksthe horn player can make decisions that may help his technical and interpretive performance." In both English and Portuguese, this book presents quick reference guides to tuning the instrumentthe harmonic series for all fingerings on both F and Bb sides of the double horn with intonation tendencies, standard fingerings,whole tone lip trill fingerings, right hand positions for hand-stopping and echo horn, intervals of transposition, and how to change a broken valve string.All the information is presented clearly and concisely, and I think this book accomplishes its goals very well. As a teacher, I tend to worry most about what happens between lessons, and I would feel more comfortable if my students, especially the younger ones, had a reference like this in their cases or book-bags that they would actually use when questions related to these areas come up during practice sessions. I especially like the emphasis on the harmonic series and its obvious relationship to intonation and fingering choices - this is probably the greatest value of this book. I also appreciate the handy chart on transpositions and the instructions for changing a broken string. With this book in hand, there are no more excuses! In all, this is an excellent collection of information related to the stated purpose.”
