that it was unrelated to any usual form. This is a pure gem, which deserves to be
much better known. The piece endswith a lively, good-humoured
Allegro
.
The
string quartet in E-flat major, K.171
also begins with a short introductory
Adagio
, this time not so very unlike the beginning of Beethoven’s String Quartet
N
o
. 14! It leads into a very symphonic
Allegro assai
, followed by a recapitulation of
the opening
Adagio
. The second movement, Menuetto, is taken up successively
by each of the four instruments, thus creating a simple divertimento. The
Andante
in Cminor (withmutes) is shadowy andmysterious, and the work ends
with a youthfully radiant
Allegro assai
: such juxtapositions are typical of Mozart,
who explores the differentmoodswith amazing luxuriance.
The
string quartet in B-flat major, K.172
begins resolutely with the four very firm
chords of an
Allegro spiritoso
, in a cloudless sky.As inMozart’s first StringQuartet
K.80, the theme of theAdagio calls tomind the cavatina
Porgi amor
from
Le Nozze
di Figaro
: languor, romanticism, a pathetic expression of ‘heart-rending love’. This
languidnessissweptawaybythefirmrhythmsofa
Menuetto
,whiletheextremely
inventive
Allegro
assai expresses a youthful carefreeness and joie de vivre.
The
string quartet in D minor, K.173,
the last of the six ‘Vienna Quartets’, is in
the key of D minor – the key Mozart used most often to express his anguish.
It begins with a magnificently structured
Allegro ma molto moderato
, which is
exceptionally long for one of these early quartets.
The Andante grazioso
is tinged
with a gravity and sadness that are somewhat reminiscent of the next quartet
Mozart composed – the first of theQuartets dedicated toHaydn – but the latter
was composed nine years later. Despite its strong rhythm, the
Menuetto
remains
nostalgic, while the fugue of the
Allegro
brings thework to a close in a climate of
pessimismand anxiety.
