The first compositions of Estonian composer Arvo Pärt (b. 1935) in the late 1950s were neoclassical piano works. In the next ten years, he began to use many of the techniques of the avant-garde: twelve tone serialism, sonic fields, indeterminism, and collage technique. The composition of Credo in 1968 set off an artistic crisis. This collage work juxtaposes quotations from Bach’s Prelude in C major with intense, almost violent passages in a modernist style by Pärt in a battle between two musical worlds. Pärt felt unequivocally that his own music was no mach for Bach’s and considered all of his compositional techniques up to that point meaningless. He withdrew from composition completely in order to “learn how to walk all over again.” He studied Gregorian chant and medieval polyphony in search of a new musical language.
He re-emerged from his hiatus in 1976 with a new technique he called ‘Tintinnabuli’ (Latin for “bells”). The new style sought not to achieve complexity and development in music but to reduce the sonic materials to only that which is essential. The basic technique involves using strict rules to combine two musical elements—pitches of a major or minor triad and a simple melodic voice—into a sort of polyphony. Pärt explained: “The complex and many-faceted only confuses me, and I must search for unity. What is it, this one thing, and how do I find my way to it? Traces of this perfect thing appear in many guises --- and everything that is unimportant falls away. Tintinnabulation is like this.”
In the case of Cantus in memory of Benjamin Britten (1977, rev. 1980), that one thing is a scale, presented in canon. After a single orchestral chime is struck three times, half of the first violins begin to build an A minor scale, one note at a time, played in the old medieval rhythmic pattern long-short-long-short. The other half of the section plays notes from the A minor triad in the same rhythm. This resultant structure--one melodic line moving against a more static line based on the triad—is the hallmark of the Tintinnabuli style. Each of the other string sections follows in turn, playing the scale twice as slowly and an octave below the section before it. The piece concludes after the double basses, descending slowest of all, reach the bottom note of the scale, A. When the strings cut off, the single chime remains, lingering quietly into the silence. One understands, at this moment, Pärt’s feeling that he had “discovered that it is enough when a single note is beautifully played. This one note, or a silent beat, or a moment of silence, comforts me.”
The impetus of the piece was, as the title suggests, related to the death of Benjamin Britten. Pärt explained: “Why did the date of Benjamin Britten's death -- 4th December 1976 -- touch such a chord in me?…During this time I was obviously at the point where I could recognize the magnitude of such a loss... I had just discovered Britten for myself. Just before his death I began to appreciate the unusual purity of his music... And besides, for a long time I had wanted to meet Britten personally - and now it would not come to that." In Cantus, Pärt maintains the strict, objective discipline demanded by the Tintinnabuli style, using nothing more than scales and triads. Yet the music powerfully communicates his feeling of personal loss. Therein lies the fascinating juxtaposition that makes Pärt’s world of sound so distinctive: with the simplest musical means, it seems audibly to hold in balance disciplined, impersonal asceticism and expressive subjectivity.
This philosophy and the seemingly uncomplicated musical style that derives from it present the performer with new challenges. Andreas Peer Kähler writes: “Pärt’s music does not call for virtuosity behind which one can hide shortcomings in technique or musicality – no exaggerated use of vibrato can replace precise intonation based on the mathematical regularities of the overtone system, or cover up the resulting irregularities. No standardized “espressivo” can replace the feeling of veracity and responsibility which the performer must develop – here and now – for each and every note.” Pärt’s music embraces the simple building blocks of music—scales, triads—and extricates them, in a sense, from the more complex musical textures of the last several centuries. It reveals the basic phenomena of music anew in the same pure, natural splendor which first captivated listeners in the middle ages.

Codebreaker isn’t a biography, complete with copious footnotes, or an exhaustive encyclopaedia entry. There are many aspects of Turing’s life that I would dearly have loved to include, but too broad a narrative arc, too meandering a musical journey, would have lessened the dramatic impact of the whole. From the outset, I wanted Codebreaker to be a portrait of a living, breathing human being and not the musical equivalent of a marble monument to a Great Hero. So I had to find the man behind the myth-making. And I found him in two ways. Firstly, through his mother’s biography (which, remarkably, Sara Turing wrote in spite of the fact that she had no knowledge of her son’s contribution to the war effort), and secondly, through the letters that Turing composed to the mother of Christopher Morcom. Indeed, Morcom was key to everything.
Turing met Morcom at school and fell deeply in love with him. It is doubtful that Morcom was aware of Turing’s true feelings; their relationship was based on a passion for science and nature; they would map the stars together. Morcom was a precociously gifted young man and showed much more potential for further academic success than Turing did at the time. Sadly, Morcom died very suddenly of bovine tuberculosis at the age of 18. And we would probably know nothing of the deep pain and inspiration that Turing took from this tragedy were it not for the letters of condolence that he wrote to Morcom’s mother (‘I shall miss his face so, and the way he used to smile at me sideways.’) Falling in love with Morcom changed Turing’s life. It would be an over-simplification to say that Turing owed everything to that single event, but I believe that the desire to fulfil Morcom’s potential for him and the later investigations into whether machines could think flow from this pivotal moment.
In Codebreaker I have focused on three key moments in Turing’s life, namely: falling in love with Morcom, the war, and his final hours. The piece begins with a prologue. The very first words (‘We shall be happy’) come from the final line of the piece, making Codebreaker circular. There follow a couple of lines that Turing scrawled on a postcard that I think demonstrate that he had a poetic soul: ‘Hyperboloids of wondrous light / Rolling for aye through space and time’. The prologue concludes with Gordon Brown’s apology on behalf of the British Government from 2009 (predating the more recent and controversial Royal Pardon). Brown’s heartfelt apology gives a neat overview of Turing’s life and delineates the narrative arc of the piece to follow.
Introductions over, the chronological narrative of the piece proper begins as Sara Turing leads us into the feelings of rapture and elation that Turing would have felt falling in love for the first time, and how that is all unravelled by Morcom’s sudden and tragic death. We then leap forwards in time by a decade or so to the outbreak of the Second World War. Although the war was a deeply disturbing time for Turing, as it was for everyone, it is also true that at Bletchley Park he was respected, revered and accepted in a way which was quite exceptional in his life. The social life at Bletchley was vibrant and colourful, though the shadow of war hung over everything, so this music is shot through with the spirit of brilliant young minds working together to one end.
At Bletchley, Turing was given responsibility for cracking the naval enigma codes, famously the most difficult enigma codes to decrypt at the time, and he did so by inventing a machine called the Bombe which greatly speeded up the process of decryption. It was one of the great intellectual feats of the 20th century. Every day bought a new code to crack which would unlock all of the German communications for the following 24 hours, so every morning there was feverish work to be done decrypting that day’s code, all the while everyone was aware that with every minute that passed thousands of sailors lives were at risk from U-boat attacks. At the time, war must have seemed unstoppable, the marching of jackboots irresistible. Yet at the same time Turing would have known this: that the natural world, the world of science, couldn’t care less about our wars, our conflicts. Nature will carry on as it always has long after we have all left this world in peace.
We then jump forward in time to 1952, the year in which Turing was arrested for having an affair with a young man. Turing, as a known homosexual who had at one time been privilege to the highest level of security information, was, at least to the British secret services, a security risk. He was, to them, an individual who could potentially be blackmailed by Britain’s Cold War enemies. And so he was hounded, his movements tracked, his friends followed. The sadness is that none of this should come as a particular surprise to us today. Edward Snowden has revealed how the US and UK governments are currently monitoring every aspect of our online lives. And it is a startling irony that our computers, Turing’s invention, are allowing them to do this. So, in 1952, when Turing was the victim of a minor robbery he reported it to the police. During the investigation it came to light that Turing had been having an affair with a young man, then illegal, and so after a brief trial he was offered a choice of a prison sentence or chemical castration, Turing chose the latter. It is still shocking to realise how recently in British history this all happened.
In the 1930s, Turing had been captivated by Disney’s groundbreaking animation Snow White and he often repeated the following line: ‘Dip the apple in the brew, let the sleeping death seep through’. In 1954, two years after his arrest and chemical castration, Turing dipped an apple in cyanide and took a bite. He was just 41 when he died. The final moments of Turing’s torment find their voice in Oscar Wilde’s ‘De Profundis' (written to Lord Alfred Douglas while Wilde was imprisoned in Reading Gaol). Having bitten the apple, Turing slips into unconsciousness. Approaching death feels very much like falling asleep, or entering a forest from which he will never be able to escape. Later, reeling from her son’s death, Sara Turing sings Robert Burns’s A Mother’s Lament for her Son.
And that is where the story ends. Or, at least, that is where it should end. But I just couldn’t bring myself to leave Turing in the dark, frightening and lonely place he truly ended up. He deserved so much better. So here it is: I imagine that, in his final moments, he would have wished to be reunited with Morcom, as he had wished throughout his adult life. Perhaps the last image that flooded Turing’s consciousness was that of Christopher Morcom’s smiling face. So that is where we leave him, standing side-by-side with Morcom under the wide starlight for all eternity. ‘We shall be happy, for the dead are free.’

Gordon Brown’s Apology
Alan Turing was a quite brilliant mathematician.
The father of computer science.
At Bletchley Park his genius turned the tide of the war.
He was treated inhumanely.
In 1952, he was convicted of ‘gross indecency.’
His sentence was chemical castration.
Two years later he took his own life.
On behalf of the British government
I am very proud to say: we’re sorry.
You deserved so much better.
Gordon Brown
SOPRANO SOLO
At boarding school, Alan met a boy:
Christopher Morcom.
Christopher had a beautiful mind.
They shared a passion for science
and would map the universe together.
Christopher was the love of his life.
CHORUS
Song of Songs
Sing me at morn but only with your laugh;
Even as Spring that laugheth into leaf;
Even as Love that laugheth after Life.
Sing me but only with your speech all day,
As voluble leaflets do; let viols die;
The least word of your lips is melody!
Sing me at eve but only with your sigh!
Like lifting seas it solaceth; breathe so,
Slowly and low, the sense that no songs say.
Sing me at midnight with your murmurous heart!
Let youth's immortal-moaning chord be heard
Throbbing through you, and sobbing, unsubdued.
Wilfred Owen
Deep in the Night
Deep in the night the cry of a swallow,
Under the stars he flew,
Keen as pain was his call to follow
Over the world to you.
Love in my heart is a cry forever
Lost in a swallow's flight,
Seeking for you and never, never
Stilled by the stars at night.
Sara Teasdale (adapted from Rivers to the Sea)
Enough
It is enough for me by day
To walk the same bright earth with him;
Enough that over us by night
The same great roof of stars is dim.
I do not hope to bind the wind
Or set a fetter on the sea —
It is enough to feel his love
Blow by like music over me.
Sara Teasdale (from Love Songs)
SOPRANO SOLO & CHORUS
Christopher Morcom died very suddenly
Of tuberculosis.
He was just eighteen.
Alan was devastated. Bereft.
I Shall Meet Him Again
He said:
I feel I shall meet him again somewhere
And that there will be some work for us to do together.
But now that I am left to do it alone
I must not let him down.
I shall miss his face so,
And the way he used to smile at me sideways.
Alan Turing (adapted from letters to Sara Turing
and Christopher Morcom’s mother)
CHORUS
I propose to consider the question,
‘Can machines think?’
Alan Turing
ORCHESTRAL INTERLUDE
The Bombe/War (including broadcast of Neville
Chamberlain’s declaration of war)
CHORUS
Turing worked tirelessly on decrypting the naval Enigma
Codes. The Atlantic Convoys, hunted by packs of U-boats,
were in a perilous position.
At Sea
In the pull of the wind I stand, lonely,
On the deck of a ship, rising, falling,
Wild night around me, wild water under me,
Whipped by the storm, screaming and calling.
Earth is hostile and the sea hostile,
Why do I look for a place to rest?
I must fight always [...]
With fear an unhealing wound in my breast.
Sara Teasdale (Adapted from Flame and Shadow)
There Will Come Soft Rains
There will come soft rains and the smell of the ground,
And swallows circling with their shimmering sound;
And frogs in the pools singing at night,
And wild plum trees in tremulous white,
Robins will wear their feathery fire
Whistling their whims on a low fence-wire;
And not one will know of the war, not one
Will care at last when it is done.
Not one would mind, neither bird nor tree
If mankind perished utterly;
And Spring herself, when she woke at dawn,
Would scarcely know that we were gone.
Sara Teasdale (Adapted from Flame and Shadow)
SOPRANO SOLO
My son was arrested in 1952
For an affair with a young man.
The magistrate offered a choice of sentence:
Prison or chemical castration.
Alan chose the latter.
CHORUS
De Profundis
I am advised to try to forget it all.
That would be fatal.
I would be haunted by a sense of disgrace;
the beauty of the sun and the moon,
the pageant of seasons,
the music of daybreak,
the silence of great nights,
the rain falling through the leaves,
the dew creeping over the grass,
would all be tainted for me.
To regret one’s own experiences
is to arrest one’s own development.
To deny one’s own experiences
Is to put a lie into the lips of one’s own life.
Suffering is one very long moment.
We cannot divide it by seasons.
We can only record its moods,
And chronicle their return.
With us time itself does not progress.
It revolves.
It seems to circle round one centre of pain.
Oscar Wilde (adapted)
‘Dip the apple in the brew,
let the sleeping death seep through.’
(from Walt Disney’s
Snow White and the Seven Dwarfs)
Lights Out
The tall forest towers;
Its cloudy foliage lowers
Ahead, shelf above shelf;
Its silence I hear and obey
The I may lose my way
And myself.
Edward Thomas (adapted)
SOPRANO SOLO
A Mother’s Lament for the Death of Her Son
Fate gave the word, the arrow sped,
And pierced my darling's heart;
And with him all the joys are fled
Life can to me impart.
By cruel hands the sapling drops,
In dust dishonoured laid;
So fell the pride of all my hopes,
My age's future shade.
The mother-linnet in the brake
Bewails her ravished young;
So I, for my lost darling's sake,
Lament the live-day long.
Death, oft I've feared thy fatal blow.
Now, fond, I bare my breast;
O, do thou kindly lay me low
With him I love, at rest!
Robert Burns
CHORUS
If Death Is Kind
Perhaps if Death is kind, and there can be returning,
We will come back to earth some fragrant night,
And take these lanes to find the sea, and bending
Breathe the same honeysuckle, low and white.
We will come down at night to these resounding beaches
[And the long gentle thunder of the sea,]
Here for a single hour in the wide starlight
We shall be happy, for the dead are free.
Sara Teasdale (from Flame and Shadow)
