II suddenly woke up and realized that my only chance to continue my musical work is to learn everything i can get about music theory, means, harmony. I bought several books and wow, there are a lot of quality differences. Some authors think the reader is a stupid idiot, just buying that book for impressing (or depressing?) his friends.

Well, the german book “Harmonielehre und Songwriting” from the authors Fritsch, Kellert and Lonardoni is not like those books. It’s a great and very, very compact reading. On a half page they might explain what the circle of fifths (Quintenzirkel) means. Well, in fact you don’t need any more explaination. What these guys write is straight forward and easy to understand. Just at a few pages there are a lack of words. This is for example when they explain the bass clef; it’s a bit to compact and you have to read carefully to understand that you can combine violine clef and bass clef. A beginner will get out very much out of this book by reading just the first 100 pages and understand, what f. e. a perfect cadence is. I recommend this book to every german speaking musician who wants to learn about harmonies and how you build them up.
