Books
My first book, The British Barbershopper came out in 2005, and the second, Choral Conducting and the Construction of Meaning was published in 2009. Both relied sigificantly on participant-observation for their research - that is, going and hanging out with the people who are making the music in order to understand what they're doing. And just as this fundamentally musical experience was essential for writing the books, the research and analysis that writing them involved continues to feed my practical music-making as director, clinician and arranger.
Anyway, here are details of both, followed by links to my publisher's website, which is the best value place to purchase them.
