This textbook presupposes no knowledge of phonology or phonetics, and takes the learner step by step through the various stages and areas of the discipline without sacrificing rigor or breadth of coverage. The extraordinary clarity of explanation by the authors make this book readily understood by anyone with a keen interest in phonology.
This was the text for my Phonology I class. We only got about as far as chapter 9, but I think that this book does a really good job helping the reader to grasp basic concepts of phonology. More than just explaining, the authors walk you through the reasoning leading up to certain ideas and methodology. The chapters are interactive with questions and exercises that you can use to make sure that you get the point.
What I really love about this book is the questions included in each unit that allow you to quiz yourself on what you're reading AS you're reading it. Really helps with memorization. Additionally, the most important terms and concepts are listed on the side of each page, which allows for easy scanning when you're short on time. Definitely my go-to recommendation for beginners to phonological theory!
