I have been a self-taught student for a long time before I attended the "Centre d'Information Musicale (CIM)" in Paris in 1979 and then Berklee College of Music in Boston (MA) from 1980 to 1982. After working in the Information Technology sector for nearly thirty years, I became a private guitar teacher in 2009. My students and my own pleasure encouraged me to write this book that I hope will be pleasant and useful to you. Teaching is a human science: your suggestions are welcomed!
