Music notation may seem a world away from business books, but the parallels are striking: when music editor Elaine Gould wrote what was to become the classic reference work Behind Bars: The Definitive Guide to Music Notation, her focus was relentlessly on the musicians who had to use those marks on the staves in performance. Good notation allows the composer's vision and the performer's skill to be translated without interference into the music the audience experiences.

'My greatest joy is going along to a concert, and the composer dashing up to me from the other end of the room and saying, "Thank you!"'

When you're translating your expertise into a book, that focus on how the reader is going to experience and use your message is equally important. Her rigorous attention to detail is inspiring, and her reaction to seeing the finished book heart-warmingly honest - I for one can empathise with this:

'When [they] handed me the first copy off the press, I was just so overwhelmed. It was wonderful. I hugged that book all the way back on the train to London, and I think I slept with it beside my bed. And in the morning, I looked up to see, was it really there? After all these years, was it there? And then it was there, and I thought you know what? For the rest of my life, I haven't got to write that book again.'
