You are now holding Volume 3 of Guitar School, which is suitable for approximately the third year of classical guitar study. Under the guidance of the teacher, students learn to play the harmony of the three tones in different variations, practice arpeggios and playing in the fifth position on the fingerboard. They develop their creativity in the Improvisation chapter and learn techniques such as staccato, flageolets and the use of dynamics. They study recital pieces that combine everything they have learned in the previous chapters and also practice their ability to interplay in pieces for two and three guitars. This volume also includes instruction in chord progressions and accompanying rhythms. Scales appropriate for each grade level can be found in all volumes. Videos, mp3 recordings and translations of all texts into English have been created as online support for the publication.  The online support is completely free and can be accessed using the QR codes provided in the book.
