Jorge Retamoza is an absolutely personal saxophonist, musician and teacher. The continuous search for him is today a registered signature in the world of tango and saxophone. His stylistic development, his facet as a composer and his contribution to the genre not only from the repertoire but also from his instrument, has managed to revitalize the saxophone in Argentina and the world, with phrases, hits and designs of all degrees of difficulty, which cannot be neither applied nor knew until the insertion of Retamoza in the current musical scene. All this creates a unique book. In this work you will find all the necessary elements (with theoretical and practical explanations, including an extensive glossary of audios played by the same author) that will allow you not only to acquire the ductility and technique to play the instrument with pleasure. Also and for the first time you will apply from the sax the gestures of tango with the precision of the style of Salg\u00e1n, Federico, Troilo, Grela, Marconi, Piazzolla or the author himself. Bend, glissandos, portamentos, slaps, frullatos, arrangements and transcriptions by the aforementioned authors are a tool displayed equally in these pages of this book, and in the audios, allowing you to address all these concepts with dynamism and resources. It is worth noting that Jorge Retamoza's work is aimed at the four commonly used saxophones, but the development of the chapters will be equally attractive and useful for other wind instruments such as flute, clarinet, oboe, etc. Melos is pleased to welcome Jorge and bring you this new tool that we believe will be of permanent consultation, interest and enjoyment.<\/p>\n
