Program Notes by John Milsom (2015)
The music of the Estonian composer Arvo Pärt (b. 1935) speaks in ancient accents, shot through with flashes of modernity. Lean, pure, and fired by the enduring tenets of the Christian faith, it shuns everything romantic, and instead hints at arcane rituals acted out in solemn ways. Pärt combines supremely well with genuinely old music, and some thrilling combinations can be imagined. Pärt and Pérotin; Pärt and Machaut; Pärt and Ockeghem; Pärt and Josquin. For this program, Harry Christophers has aligned Pärt with two Tudor composers, Thomas Tallis and William Byrd, a pairing made all the more apt by Christopher’s choice of some English works that are themselves composed rigorously according to logic and rule, or address the fusion of old with new. Here, Tallis and Byrd meet Pärt on common ground.
There are times when a composer may concern himself with aspects of craft that are hard or even impossible for the listener to follow. Audiences find this puzzling, and deem such works to be cryptic and mathematical. If music is by definition sound – humanly organized sound – then why organize sounds in such ways that the listener is excluded? The point is neatly made by this program’s opening work, Byrd’s eight-voice motet Diliges Dominum. Words apart, it sounds the same backwards as it does forwards. The piece is a perfect palindrome, yet no one could possibly know that from performance alone. Our brains cannot process temporal symmetry in the way we instantly see visual symmetry.
Why, then, was this weird work written? At least three answers come to mind. First, Byrd composed it because he could. If carefully chosen, chordal sequences and melodies will work both forwards and backwards, and Byrd must have loved the challenge of working this out for himself. Second, he wrote this crab canon for the delight of the eight singers who, using Byrd’s original notation, must read from only four melodic lines. Four of them sing these melodies forwards, the other four sing them backwards; and by doing so, their eyes unlock the work’s musical conceit. But Byrd’s third reason for composing this piece may be the most important, for he placed it in a book that ensured its readership across Europe. In 1575, Byrd and Tallis jointly published a collection of motets called Cantiones sacrae (‘Sacred songs’). It was dedicated to Queen Elizabeth, and it was explicitly made for export, to display the brilliance of Tudor culture to the outside world. Small wonder, then, that both Tallis and Byrd do some musical showing off in these motets.
The most breathtaking piece in the 1575 book is the one placed at its end: the seven-voice Miserere nostri. Usually this work is credited to Tallis alone, but more likely it is by Tallis and Byrd, the two men working collaboratively: first four voices composed by Byrd, then three more added by Tallis. The strange beauty of this piece hints that something arcane lurks under its sonorous surface, and indeed it does – but it can only be grasped by viewing the piece from the singer’s perspective, since it too is concerned with sight as well as sound. Just three notated lines are needed to convey this work’s seven-voice polyphony, two of them bearing instructions (or ‘canons’) telling how they must be deciphered. The first melody, attributed to Byrd in the 1575 Cantiones sacrae, is to be read by four low voice singers, all starting on the same note at the same time. The first of them sings the line exactly as written. The second doubles all the durations of the notes (x2), and turns all the intervals upside down. The third singer quadruples the durations (x4) and restores the intervals. The fourth octuples the durations (x8) and re-inverts the intervals. Thus four different versions of the same melody sound simultaneously, in various states of augmentation and inversion – a conceit that is utterly impossible to follow in sound. Byrd then handed this to Tallis, who deftly added a superstructure: two sopranos sing in straightforward canon at the unison (very easy for listeners to hear), and a free seventh voice plugs some polyphonic gaps. Miserere nostri, Domine (‘Have mercy on us, Lord’) are all the words supplied for this lean and logical motet.
Other works in this program play compositional games, some more easily discerned than others. Simplest to follow is Byrd’s game in Christe qui lux es et dies. Five voices are in play here, and five stanzas of text are set to polyphony. In turn, each voice sings the traditional plainchant melody used for this hymn, starting with the bass (polyphonic stanza 1), then rising through the texture to the soprano (polyphonic stanza 5). Each statement is harmonized in simple block chords filled with surprises – not unlike the choral chanting favored by Arvo Pärt, in which strings of consonant chords are locally spiced with piquancies. Cleverer by far is another of Byrd’s motets from the 1575 Cantiones sacrae – ‘cleverer’ in the sense that it took immense skill to devise, even though that skill frankly bypasses us in sound. In Miserere mihi Domine he does ingenious things with the plainchant melody of the same name – including, near the end, a two-voice canon made from the chant, interwoven with a second and totally different canon sung by two more voices. Strange rituals, indeed.
