As a music student, who attempted to take Music History I, with this textbook being assigned, I will say, that while this book is good reference, it is quite wordy and, at times, unclear for how certain pieces of information are included (i.e., madrigalisms, harmonic thirds and sixths [as it applies to the English style], etc.).
Although, I rated this book a three, it is more accurate to rate it a 3.5 due to my positive, yet conflicting, feelings on this book.
Do I believe that Burkholder comprehensively outlines the history of different eras, along with their characteristics and compositional techniques? Yes.
Do I believe that this book is easy to understand? To a degree.
Yet, at least for me, this is where the problem lies. It is not that Burkholder hadn't had written something that was understandable, It is that he had written something that was not as clear. Whenever I reminisce about my experiences reading this book, I often become reminded of the lack of clarity regarding specific terms or definitions, such as, "what is a motet?" or "What is a madrigal or madrigalism?"
While the book provides provides proper historical context, both historically and musically, it fails to simplify the information in a way that would lead the reader to being able to easily identify what a specific term or characteristic is. Instead, at least in my opinion, it provides a lot of context with the meaning being hidden within the details (i.e., "fine print").
While I found the basic structure of the book to be helpful, I found that it lacked support within specifics becoming more dense and wordy than anything else. This is unfortunate, as a textbook should be clear in it's identification of terms, or characteristics, when it applies to a student's success. As it is relevant to gain knowledge, and take it away for the purposes it applies to, either as a teacher, musician, composer, writer, or scholar, it is equally relevant to have a book that presents information in a straight forward manner.
In other words:
If I am looking how to define a motet, I should be able to have that defined in clear and concise language. What is rather disappointing, is that while that is given, it is done so through a mixture of historical context, that leads the text to not be as clear as it is.
As always, with any academic music history textbook, or music textbook in general, the emphasis is on musical analysis. Burkholder, who I will give some credit to, has a means of outlining the analysis portion of each chapter in a way that is easily understood with each term, and musical characteristic, corresponding to the appropriate context, as it applies to the style and era.
Overall, this is less of a textbook and more of a reference guide for topics such as:
"Who court musicians were."
"How imitation was used within the era of the Renaissance."
And many other questions. Unfortunately, it does not provide the form of providing the reader with a definition and then expanding on it's usage in it's given era. This, at least to me, through my own experience, is the negative, downside to this book. As with other users who feel burkholder should be given sympathy, this seems, to me, irrelevant as any assigned textbook should follow the protocol of "less is more" and "work smarter not harder."
If I am using this book to provide myself with a successful outcome, or in other words, a grade that allows me to pass the class, it should serve as a means of being simplistic enough to easily answer any questions I have, regarding terms, characteristics, or styles, and be in-depth to provide context to these elements. Burkholder, in my opinion could have eliminated any attempts at being dense or wordy, as it only contributes to the lack of cohesion, and relation, this book would form with any material needed forthe specifics of fulfilling what is asked as a student.
Apart from a student, I find this book to be a good reference, BUT NOT, a proper source of literature for the history of western music. I will admit, that I have no alternatives, primarily, because music history is only quantifiable when you understand the era. There are no shortcuts, and if there was a book to be chosen that could act as a summary, I would choose the Burkholder, but only because it serves a means to an end becoming the best, IMPERFECT example of how music history can be summarized.
In summary:
Proper reference, with constructive applications of different terms, or characteristics, as it applies to it's extensions and uses, but wordy and dense when relating to the defining's of these terminologies and elements. If the text was more minimal and straight forward, it would be of more value.
