Apart from a few notions in college, music theory was for me, to this day, a large nebula. Young retired, I decided to learn to play the clarinet. Before waiting for the next school harmony back of my country, I decided to start studying alone, it targeted theory "beginner". Book super well designed: simple, clear, precise, complete. Of course, it remains a theory! But really affordable for everyone MOTIVE. Finally format: 10.5cm x 16.5cm - 159 pages (very readable characters), we can take him and study everywhere, from the moment you have five minutes. CONCLUSION: A book very minimal expense for un.ouvrage "beginner" major, indispensable.
