The opening solo piano
repeats the same phrase twice,
building allegro, staccato,
with a sound that is sunny and bright.
At ten seconds
the orchestra enters
and repeats the piano’s part,
as we move into diminuendo
and the strings come to the fore.
The whole rises and falls.
The higher-pitched strings
float, glissando, up above it all.
The lower-pitched strings
hold an underlying staccato.
Between solo and orchestra,
the dynamic range expands.
Solo and tutti explore
emotional dialogues
to a turn of recognition
as they seek for a surprise.
A brief phrase of only four notes,
which is twice repeated,
without the final fourth note,
is then, repeated in full.
These notes are neatly pinpointed
by an increase in swelling dynamics
on each first note of the phrase.
After thirty-four seconds
a note takes the air
from woodwind sustaining a breath
leading into a swelling melody
from the strings with a smooth,
rich texture of resonant sound.
The original tune is repeated twice,
glissando, by the strings,
introducing the horn in the second repeat.
The sound becomes transparent,
while the dynamics slowly increase.
The structure consistently rises,
then cascades downward in ripples,
triples, suggesting a shifting breeze
coming to rushing crescendo
at moment 01:01.
There is a brief finality, at 1:04,
with an emphatic chord.
At 1:05 the piano solo
re-enters with tender grace
and a poignant interpretation
follows the melody.
There is a key change to the minor.
The heart lurches and weeps.
From 1:30 to 1:44 the orchestral accompaniment
gradually becomes emphatic,
more, with a falling scale
behind the rising solo
which is repeated only twice.
The next section concludes
with a final note, down,
on the piano at 2:08
and an orchestral chord
followed by a silence
of one brief vital pulse.
At 2:11 the piano
seeking heaven,
makes an allegro,
bright and joyous return
to the main melody
this is echoed
by the orchestra
with amplified dynamics
until 2:46,
when the orchestra plays
a stately passage,
which the soloist repeats.
At 2:53 the soloist brings
a series of ascending scales
in allegro repetitions
until 3:06 when it’s mirrored
in reverse
in repeating descending scales,
against a simple staccato beat.
This repeats with increasing dynamics
dancing until 3:17
skipping between
and then calms until 3:27.
The orchestra falls silent.
The soloist is alone,
seeking heaven,
with repetitious notes,
entering a rapidly descending scale
until 3:40 which reverses, to ascend,
before falling, pianissimo at 3:39.
There is again a pause of one pulse.
So fine, so touching, the heart skips a beat.
As the fourth minute begins
the solo brightly repeats, allegro,
the central melody twice.
The final ten seconds are tutti, played forte
with final force.
The piece is sometimes playful,
sometimes wistful and poignant,
more beautiful for the contrast
between yearning and joyousness.
Mozart plays with emotions
just as he plays with the keys.
Music surpasses words.
