Book Review: Bio-Guided Music Therapy: A Practitioner's Guide to the Clinical Integration of Music and Biofeedback

London’s book is not always easy to follow. The opening sections have a technical feel, emphasised by the use of abbreviations such as IOI (inter-onset interval) and milliseconds, rather than ‘beats per minute’, to describe time intervals. However, this is arguably necessary to his project of grounding metre in more neutral empirical research. Once more musical language is allowed to enter the discussion the book becomes more approachable (at least to me as a musician), and the concepts more intriguing and intuitively appealing. I have long felt that there is far more to metre than the time signatures we learn as novices. London’s book offers a sophisticated, if sometimes awkward, language to describe the subtleties of metre. But his real contribution is to remind us of the importance of the phenomenon itself. In the house of music there are indeed many metres.
