I've been Editor-in-Chief of the Leonardo Music Journal since 1997. Each year we produce a print issue and audio CD on a theme of my choosing. The bulk of the writing is by artists about their own work, and for each volume I write an introduction in which I attempt to link the various papers. Issues I have edited include:

• Improvisation

Our Crowd -- Four Composers Pick Composers

And in 2000 I was asked to write a statement on the 10th anniversary of Leonardo Music Journal for Fineart Forum Vol. 15 No. 1 (Jan. 2001), which was subsequently published in Leonardo Electronic Almanac Vol. 9 No. 2 (2001).
