How Slowly Dark - a musical tribute to pianist Noreen Stokes

Noreen Stokes records for Radio Malaya in September 1957,
three years before migrating to Australia.

 My latest piece, How Slowly Dark, is a humble attempt at a musical tribute to my late mother Noreen Stokes O.A.M., retired concert pianist, accompanist, and piano teacher. Her tragic and inexorably increasing blindness, eventually almost total, ironically paralleled the deafness of her beloved Beethoven.

The idea behind How Slowly Dark leapt at me the moment when I read Theodore Roethke's haunting and melancholy lines:

The piece is a dream-soundscape, deliberately rather formless and wandering - as dreams are. (I could make a score, but probably no-one will want to perform it... so why bother?) Strands of familiar piano music float from my childhood into the present moment, evolving on their journey into an aural tapestry, a private look into my mind's inner ear. Where will these fragments travel after this? And likewise, what is it that each of us might, in turn, bequeath to the future?
spacer
In particular, the music attempts to acknowledge the fundamental influence of mum's pianism on my guitar playing years, and later, extrapolating beyond that into my present composing. Even in my early years I used to comment that I wasn't really playing a guitar at all, but imagining a piano with a neck.
spacer
Instrumentation comprises: Piano, Classical guitar, Strings, ATTB choir, and tuned Percussion.

The opening fades up into a brief passage from Liszt's La Leggierezza, a virtuoso concert study which requires from the pianist a light, nimble, lyrical, and understated touch. The piano crossfades into a guitar adaption in a new key (as, in my misspent youth, I was often fond of doing).
spacer
Enter J.S.Bach - unexpectedly - smack in the middle of the guitar passage. One of the concealed elements glueing this patchwork dream together is a Bach Chorale, the same one borrowed by Alban Berg for his Violin Concerto, his tribute to Manon Gropius. Es ist Genug ("It is Enough, Take Me Now") was one of the last chorales written by the ageing Bach when he was going blind: I therefore deemed it to be eminently suited to the present circumstance, especially given that my mother enjoyed learning German. I borrowed Bach's melodic tritone (G, A, B, C#. See Box 1, below):
The opening of Bach's chorale Es Ist Genug, performed as 'vocalise' on this recording.
The original key was A-major, highly symbolic because Bach symbolised its three
 sharps as the crosses on Calvary Hill. Hey, one cross is enough for me. 
(PS: Bach is not responsible for the last few notes).
spacer
 Although the fragment in Box 1 is entirely tonal, functional, and - yes - 'legal' in Bach's harmonic language, I nevertheless grasped the opportunity to fashion the whole tone scale into un-Bachlike whole-tone harmonies, especially my beloved augmented triad. As a child, my ear gravitated instinctively towards any occurences of augmented triads (major triad with sharpened fifth degree), although then, of course, I had no technical words nor understanding, just feeling. Here, today, it constitutes the perfect compositional excuse to evolve towards Dubussy, yes? Sure, I can do anything I choose inside my own dream. The dear old augmented triad has not dulled with age or familiarity... formal musical education has failed to erase its melancholic magic (thank goodness).
spacer
But Bach can always be mined deeper. Box 3 (see the bottom of the score) is a series of rising chromatic semi-tones. This motif becomes a "pillar of the temple" in the dreamworld of How Slowly Dark, woven throughout the entire piece no matter which composer happens to be at hand. The observant ear will already have detected it pervading the Liszt-based passages for guitar and choir. Liszt beat me to the idea, dang it. Fragments of it - as well as the whole-tone elements - emerge and recede frequently in the fabric of the sound like a kind of structural glue. Eggs in the musical cake-mix, perhaps. The chorale is only quoted at any length at the very end of the piece - as was Bach's own habit in his Cantatas. It may be worthy of note that both these elements, the whole-tone scale and the chromatic semi-tones, rise in pitch - and (hopefully) in spirit - surely an appropriate metaphor for my mother.
spacer
At about 20sec, the strings fade up in C major during the E major guitar passage, converging on a cadence which merges the two keys into a chord of E augmented (E, G#, B#,  which is enharmonically equivalent to a chord of C augmented, ie C, E, G#):
(Interesting to note, by the way, that Es ist Genug is the only
one of Bach's chorales in which He used all twelve tones)
spacer
 The F, F# and G of the cello and double-bass are part of a normal formulaic Baroque cadence in the key of C major (implying ii - V/V - V), whereas in the context of E major, Liszt's E#, F# and F-double sharp perform a highly chromatic and purely melodic/colour role. Aligning these enharmonic notes whilst superimposing and contrasting their keys makes for an interestingly ambiguous cadence: is the root C or E? In effect, it's both, really - the guitar's low E is very close in pitch to the cello's C, so there is no obvious front-runner in terms of the chord's perceived root note. After this brief Ives-inspired side-trip (thanks, Charles!), the guitar resumes briefly back in E major - just as if nothing had happened. Perhaps it hadn't even noticed the choir...
spacer
As the guitar fades, the dream drifts into a meditative choral arrangement - the same piece of Liszt, yet utterly transformed. The paradigm Piano > Guitar > Third mediuma sequence neatly summarizing my entire musical life (as in "Listener, then Guitarist, lately Composer"), sets the underlying format for subsequent sections of the piece.  The choir begins multi-layering the rising chromatic motif in the manner of an introduction, after which it presents a quartal re-harmonisation of the four-square Liszt melody.
spacer
As the voices fade on a cadence of C augmented, who should materialize out of the mist but Monsieur Debussy. The first movement of Debussy's Pour Le Piano deliberately explored augmented chords by using them in a non-functional and colouristic manner (ie requiring no 'resolution'). Rebellion! Mutiny!  Mozart's Universe turned on its musical head. Crikey, these chords were no longer expected to resolve to pre-ordained destinations - they could just "be". I recall as a child hearing my mother play Pour Le Piano and vaguely thinking "Hey, there's that funny sound again... and gosh, there's another... and another!" Interesting to reflect that Debussy's piece was composed in 1901, a mere sixteen years before my mother's birth.
spacer
 Meanwhile, Bach's chorale again looms up like a pale watercolour wash to provide a ghostly background floating behind Debussy's stridently rhythmic piano chords. This time the choir offers the rising whole-tones of the opening phrase itself, Es ist Genug: It is Enough.
spacer
 As per the blueprint, Debussy's piano gives way to a guitar adaption - necessarily a thin-blooded mock-up and hardly a match for the piano, of course.  What was I thinking! Thankfully, stimulated by Debussy's strings of augmented chords, my dream dissolves into a more guitaristically sympathetic and lyrical passage of guitar with string accompaniment. This is actually a brief quotation of my own piece for chamber orchestra, Reconciliation, whose sound-world seems (on the surface) to be as stylistically remote from Debussy's pianism as it is possible to be. Nevertheless, in musical terms, it is closely DNA-related by its free use of of augmented harmonies à la Debussy. Thank you so much... may I call you Claude?  And of course - equally - thank you to my mother for performing it so sublimely. Both pieces do what Herr Bach would have considered ridiculous and illogical - attempting to tonicize/stabalize a chromatically-altered chord whose normal "Common Practice" syntactic function is that of a species of dominant (by its nature inherently unstable).
spacer
 After the string passage, the violin evaporates in a rising whole-tone scale (generated - again - by the augmented harmony), into which Chopin delicately floats the theme of his Ballade No 1, another pianistic pot-boiler from my youth. My mother adored Chopin, who, in his heart-warming and enlightened Romantic Wisdom, invariably managed to remember to obey The Golden Rule which obliged the sharpened fifth note to resolve by step (in this case, Bb to A):

 But the ever-observant Guitarist :-) notices the rising augmented triad (bracketed above) and immediately feels inspired to let loose a volley of three successive augmented arpeggios, each one beginning a semi-tone higher, recalling the earlier chromatic motif. In this manner the two motifs, based respectively on the whole-tone and the semi-tone, are finally merged, and thus the circle is completed. And not even one of the augmented chords feels any pressure to resolve. Do I pass my test, Monsieur Debussy?
spacer
 Several passing percussionists, one of whom may well have been Toru Takemitsu, notice the three semi-tone motif and decide to play with it as a cat teases a mouse. This continues in a rhythm-free microtonal zone until the guitar steps in, tentatively takes matters into hand by re-instating tempo, crystallizing an unexpectedly conventional cadence, and framing attention back onto the piano's final entry. We hear a snatch of Schumann's Papillons (from Carnaval Op.2, another of my mother's epic favourites), before it disintegrates into nothingness. It is in its original key of C, even though this fragment begins on its V chord (G). The tonic C is only implied, not stated.
spacer
 The Schumann is soon comprehensively submerged by the Chiangmai Bach Choir's otherworldly vocalise of the entire opening section of the chorale Es Ist Genug continuing in a radiantly clear G major, thereby prolonging the dominant of C.  Its three phrases, too, fade slowly, glacier-like in their tenacity and endurance - almost as if locked in a hapless struggle against inevitably encroaching Darkness. Heightening the sense of "unfinished-ness" is the fact that although the chorale begins anchored on the tonicized centre of G, the last phrase skids off a banana-skin C# towards its dominant key, D. But not only that, but you land gingerly on a very un-final and slippery triad of D augmented. The music ends before it finishes, awash in a sea of ambiguity, heart-breaking pathos, and incompletely fulfilled potential. One thing's for sure, whatever comes after the final silence is always up to you.
spacer
By now the final three notes of the chorale excerpt (G#, A, A#) will probably be more self-explanatory (refer back to Box 2 in the first diagram). Analytically, the final harmony could be C: II#5, ...or perhaps C:V#5/V ...or your ear might demand G:V#5 (or even D:I#5 if you were totally outfoxed by the persistent C#) ...but aw heck, who really cares? It feels tonicized/completed in a strange kind of a way, but it isn't. It can't be - unless you decide to let it. Whatever the case, the Memory will probably linger in your mind after the Sound has died away.

 By Xmas 2007, mum could just manage to see a small faint area under strong lights.
She still maintained her discipline of technical practice every morning from 7-8 am.
Nowadays (2011), she feels too disheartened to even attempt to go to a piano.

RIP at long last, Mum.

Fibonacci's Rabbits - the sound of one mathematician thinking.

Many things in Nature, such as cabbages, pine-cones, sunflowers and snail-shells all grow in spiral patterns controlled by the series of numbers known as the Fibonacci Series. The 12th century mathematician Leonardo Fibonacci discovered that exponential growth occurred if the last two numbers of any series were added together (eg, 1+1=2; 1+2=3; 2+3=5; 3+5=8; 5+8=13; 8+13=21, etc). As with Bartok, who always composed with a pine-cone on his desk, these numbers provided the very simple genesis for my short piece "Fibonacci's Rabbits".
 
When considering the dimension of musical Pitch (assuming one is counting by semitone), the Fibonacci Sequence neatly generates the ratios which create the intervals comprising the major triad. The 'cell' in the first bar-and-a-half of my piece, for instance, outlines the triad of C-major. At this point I choose to bypass the usual debate arguing "Co-incidence or Causality?" ...as that is not my purpose here.
 
The Fibonacci Series can also be applied to the dimension of Time. Counting by demi-semi quaver (DSQ), my cell exponentially stretches out in time-values as the numbers of DSQ obey the dictates of the series.
  mm
Once I had established the mechanical aspects of this cell, however, Rationality was summarily overuled by Art. I proceeded to present the cell in the freely imitative fashion of a Renaissance motet, symbolic of the ordered growth yet highly chaotic interaction of plants in Nature. This image was triggered in the first instance by watching the astonishingly rapid growth of the Climbing Spinach Vine on our balcony in Chiangmai.
spacer
The Fibonacci Series can be taken a step further - to suggest Form in music. As the ratios of the numbers spirals from 1+1=2 right through to higher numbers such as 13+21=34, 21+34=55 and so forth, the ratio increasingly accurately converges towards the decimal fraction 0.618, known as the 'Golden Mean', an irrational mathematical constant. View more complete examples here and here. In my example, the number 21 comprises approximately 0.618 of the number 34. Hence in my music, not unlike the music of countless other composers throughout history, I engineered the the climactic point to occur at about six-tenths of the way through - an aesthetically pleasing proportion which defiantly avoids symmetry. Botticelli's 'painting, the Birth of Venus' is a visual demonstration of the principle. He even included a shell for good measure.
mm
I gleefully noted the presence of the G# just after the triad in my cell, which immediately authorized me to write my beloved augmented triads (C-E-G#). The successive entries of the cell in the keys of C, E, and G# (bars A/B/C) resulted in the extended high-pitched augmented triad which materialises in the high notes towards the end of Bar 6:

Similarly, personal choice determined the extended quartal harmonies - traditionally and accoustically  more stable/final than augmented triads - which serve to conclude the piece:
The final gesture includes the only instance of a cell which falls in pitch - symbolic, perhaps, of decay and death  as the necessary counterbalance of growth, the ends of empires, the eternal wheel of life.
 

Other interesting stuff about the Fibonacci Series:
* The piano keyboard from C to C has 13 keys comprising 8 white keys and 5 black keys, split into groups of 3 and 2.
* In any key, the 'dominant' note is the 5th note of the scale, which is also the 8th note of all 13 notes that comprise the octave. Note that 8:13 = 0.61538, which approximates phi. It's precisely that assymetric wildcard which makes a musician's (and theoretician's) life interesting and happily irrational.
* The spiral layout of cabbage leaves ensures that the smart little plant receives the maximum possible sunlight over the span of a day.
