Book Review: This is Your Brain on Music, by Daniel J. Levitin

Before I begin, let me just say right off that I enjoyed reading this book a whole lot and I heartily recommend it. The following harsh criticism is partly because I care enough to wish it was just a bit better, and partly because its subject matter falls in my own area of expertise (psychology), so I'm bound to be nitpicky.

This is Your Brain on Music explores the science behind music, drawing from the latest research in psychology and neuroscience to explore various facets of creating and listening to it. After reviewing some basic information about music and music theory (most of which was new to me), Levitin begins describing the science behind topics such as categorization of music, the role of emotion in music, and musical expertise.

My first beef with the book is in its accuracy. Vague hypotheses and tentative research findings are often presented as established fact. However, this is to be expected in any science book written for a popular audience (again, me being a nitpicky psychologist). But there are other little errors. Levitin briefly mentions that Canadian psychologist Glenn Schellenberg was an original member of the popular 80s band Martha and the Muffins. However, a bit of Googling reveals that Schellenberg seems to have only played a guest role on a later album of theirs.

This only caught my attention because I'm currently running a study that Schellenberg kindly provided some audio files for. And speaking of name dropping, Levitin devotes many words to telling us how many famous people he has chilled with. At one point, he suddenly goes from talking about the role of the cerebellum in music to an elaborate tale of how he attended conferences with all his scientist heroes and even met Watson and Crick. This autobiographical stuff is interesting enough, but it ruins the flow - the rhythm, if you will - of the scientific stuff when the two are carelessly mashed together.

This haphazard organization is also exemplified in the book's final chapter. During a discussion of music's primary role in human evolution that is finally starting to lead somewhere, Levitin suddenly jumps to a vague hypothesis about mirror neurons fueling cultural evolution, then jumps again to a rambling, repetitive paragraph that pretty much says "humans live in groups" 5 times in 5 slightly different ways, and then, the book ends. No real final thought; no paragraph even trying to tie the preceding chapters together, just a random stopping point when he ran out of facts and anecdotes to throw onto the page.

Did I mention I liked this book? While it may be a disorganized collection of facts about music, each fact is fascinating on its own and well worth reading about. We often fail to think very much about the music we listen to for hours out of each day, and This is Your Brain on music, while it could use improvement, is an eye opening exploration of the deeper layers of the magical human experience that is music.


Side note: In this post, I wondered about the underlying reason for certain musical conventions. For example, why do minor chords sounds sad? Is it arbitrary and cultural? Or is there a more concrete reason? This book answers some of those questions. Long story short, like usual, it's both. The laws of physics are responsible for some combinations of sounds going well together, but arbitrary choices and conventions also play a large role. E.g., apparently not every culture thinks minor chords sound sad. Interesting stuff.

Rad. I love this topic and wanted to read this book, but too many people had it reserved at the library (and I'm too cut-my-own-hair cheap to buy it). I settled for Steven Mithen's Singing Neanderthals instead, which comes from more of an anthropological perspective. Interesting either way.

What was the vague hypothesis about mirror neurons and cultural evolution?

He speculates that mirror neurons fire when hearing a musician perform, preparing our brains to echo music back to other people. Then he goes on to speculate that mirror neurons and iPods are responsible for transferring music across individuals and generations. I wish I could explain this so it makes sense, but really, I think he was drunk when he wrote the last few pages of the book.

There probably are better books on the topic. Singing Neanderthals sounds interesting. Also on my reading list is Musicophilia by Oliver Sacks.

Freaky timing, I had a tipsy *hic* discussion about this book on Saturday night with two other musicophiles (sometimes I make words up) who'd also recently read it.

Interesting stuff. Though I have to admit I slogged through some of it... me not having any letters beside my name and all.
