On October 22, 2014, I published my first book in this series. It was a small but important summary of music theory covering harmony, ear training, and music analysis for the instruments piano, guitar, bass, and drums. Arranging and composing. After the book was released, I immediately knew that I wanted to say much more and perhaps present some things even better. Here is now my second edition of "Your Little Music Encyclopedia." It will be a great helper for many questions that arise while making music. It can also be used as a textbook for school lessons, and many colleagues will be able to gain a structure for their own teaching from it.
