I wasn't sure what to expect when I began reading this book, and to be perfectly honest I'm not sure what I think now that I've finished the book. I'm very interested in the type of pop psychology theories that show you how to change your life based on routines or life hacks, but this is something on a different plane entirely.
I should probably state up front that I'm not particularly a huge music fan. I like music just fine, but I would compare myself to a casual wine drinker, and to the likely audience for this book being oenophiles. I can enjoy my malbec or merlot without needing to know where it came from or what makes it taste good, and I can tap my fingers along to the radio without caring about the beats per minute or the effect on my brain activity pattern.
Still, I'm aware of the power of music. The playlists my yoga teacher puts together get me focused, push me through the hard parts, help center me when my mind wants to wander, and give me a wonderful uplifting feeling at the end of class. During a rough breakup several years ago, I noticed that the only time my mind calmed and I felt happy were during dance classes, particularly during choreographies with upbeat melodies and fast beats. The blend of music and movement for me is a very powerful one, but I'm not inclined to take it much further than that. I don't collect music and rarely care who sings a song or what the lyrics actually are, so the exercises in the book seemed really overwhelming to me (more on that in a minute).
The main thesis of this book is the fact that the plasticity of your brain allows you to use music as a trigger to increase your happy moods, decrease your bad moods, enhance concentration and otherwise affect anything you do that requires brainpower - in other words, pretty much everything. The book intends to help you in determining what music allows you to develop and sustain the best pattern for your brain waves, and to create playlists for various purposes to achieve those goals.
However. Some of the claims made by the authors make me very wary. For example,"Many people have reported that they have been able to reduce and even completely eliminate their need for sleep and antianexiety medication as a result of [brain music therapy]" is, to me, a very concerning sentence in the middle of a more concerning chapter about how, by spending time arranging playlists and listening to music, you can disregard what other mental health experts treat as depression, self-harm/mutilation, anger, and other problems generally addressed by talk therapy and/or medication. I'm sure the well-educated authors didn't intend for the advice in this book to be taken in lieu of a doctor's advice (I HOPE), but they sure don't say that in the text. (And seriously - music replacing the need for sleep? No, thanks.)
Back to the exercises. Each chapter includes sample playlists and exercises to help you develop your own playlist of music that works for you. They're clear that music that you personally like makes the best impact on you, so their suggestions are eclectic and inclusive. However, the exercises require a lot of time spent finding music, organizing it, continually updating it, and spending focused time listening to it (practicing, effectively) in order to create the desired associations in your brain. "But you can't expect to just turn on your CD and see immediate results as if you were popping a pill. To best train your brain, you need to listen to the files regularly over a period of several weeks," they note. It winds up being serious time, on the order of 15 minutes minimum listening time per day per playlist, plus requires you to regularly listen again during times of stress - so, at work or in other settings where it's not likely to be appropriate or manageable. Meditation and breathing exercises seem to me to be just as useful and much more unobtrusive.
However, I don't think I'm upset at the lack of a "quick fix" - the book mostly seems to be a solution to a problem I'm not actually sure I have. Since starting the book, I at least began to pay a little more attention to the music that I already listen to (in the car, in a grocery store, in the background) but I can't say I'm willing to dive in and spend time in the rabbit hole of iTunes trying to come up with something that will change my life - a life, incidentally, which seems easily managed without the help of a playlist.
Verdict: interesting reading, but I find the presentation both too simple and too complicated at the same time.
