This is very readable. It's a good overview. I wish it had better footnotes. I particularly enjoyed the discussion of Greek influences on music that are still present today, as well as the discussion of African polyrhythms.
Sadly, as so often happens, the "History of Music" section is really a history of Western music, and music of other areas of the world is shunted off to a separate section rather than being integrated into the main narrative. This is better than if other areas weren't covered at all. But I found it particularly irritating that, for example, the South American music timeline begins post-colonization, even though the discussion does contain some info about music from pre-Colombian cultures. The so-called African music timeline is even worse, as they start it in about 1960. It's all a little too Eurocentric for my tastes.
Recommended conditionally, as I haven't found anything that addresses the history of music any better. Maybe someday.
