Excavating my desk recently, I found the program notes from a Tallis Scholars concert my wife and I had attended a few months ago. The Tallis Scholars are a marvelous a capella ensemble, but most of their music that night was rather too minimalist for my tastes. In any event, the author of the program notes described Arvo Pärt’s I am the true vine, and its “qualities of stasis and timelessness,” as reminiscent of what “former Archbishop of Canterbury Rowan Williams has described as ‘silently waiting on the truth, pure sitting and breathing in the presence of the question mark’.”
