Guitar Zero: The Science of Learning to be Musical

The book is widely praised for its engaging exploration of an adult's journey to learn the guitar. Author Gary Marcus, a psychology professor, imbues his personal narrative of starting music later in life with scientific insights into how the brain learns. Reviewers found his blend of personal anecdotes, interviews with famous musicians, and cognitive science both inspiring and accessible. Many appreciated the thoughtful discussion on the roles of talent and practice, the differences in learning between adults and children, and the underlying principles of music theory, all presented in a way that avoids academic dryness. The overarching positive message that adults can successfully pursue musical dreams at any age resonated strongly with readers.

However, some readers expressed disappointment, feeling the book did not deliver on certain expectations. A common criticism was the lack of practical, "nuts and bolts" advice for adult learners, with many hoping for more actionable guidance on how to learn an instrument. Several reviewers also wished for a greater focus on Marcus's personal learning journey, finding that the book leaned too heavily on general theories and academic discussions which, for some, felt obvious or shallow. Disagreements arose regarding Marcus's dismissal of certain evolutionary theories of music, and a few noted that some questions about musical ability were raised but not fully addressed.

Ultimately, the book is considered an interesting and thought-provoking read, offering a unique blend of memoir and scientific inquiry rather than a straightforward instructional guide. It is highly recommended for anyone interested in the cognitive psychology of learning, the science behind music, or the human capacity to acquire new skills at any age. Aspiring musicians, particularly those who are adult learners, will find encouragement and a deeper appreciation for the musical journey, even if they don't receive direct playing tips. The book appeals to those who enjoy intellectual exploration and a balanced perspective on the interplay of dedication and innate ability in mastering a complex skill like music.
