I am incredibly pleased to present Mastering MuseScore, the definitive guide to MuseScore 2. I have been working on this book for the past two years, in conjunction with my contributions to the development of the software plus my teaching and whatever gigs I could fit in. If you are a MsueScore user already, or are interested in learning about what is possible with free and open source music notation software, you will love this book. I wrote it to be as comprehensive as I could, covering every feature, every option, every trick I could think of, and yet I start with the absolute basics, so beginners can get going right away. Sales of the book directly benefit the further development of MuseScore. Please check it out!
