This harmony manual is for everybody, not only for those who have already studied it or play an instrument. On the contrary, it would be a reading method for 6-years-old children as well as for anybody who has no musical knowledge. Harmony, the art of tuning sounds, should be part of our knowledge and it is this familiarity that will make us able to play an instrument. This base course is organized in 35 lessons and, as a maths course, is attachment to each one there is a guide exercise as a help for your homework. Indeed, I find some similarities between these two subjects and especially those people who are suitable for scientific studies should find no problems in attending this course.
