Franz Schubert, String Trio No. 1 in B flat Major, D581
The four movements of the Trio, D. 581 (1817), which is scored for the
usual trio ensemble of violin ,viola, and cello, are all of rather moderate
tempo, as follows: Allegro moderato--Andante--Allegretto (Minuet and
Trio)--Allegretto (Rondo finale). It is perhaps in the opening
movement that we hear Schubert's unmistakable voice most clearly, for
while on the surface this very brief sonata-allegro form movement
would seem to have little in common with the expansive kind of sonata
movements Schubert would come to compose a little later on, the
chromatic twists of both counterpoint (passing tones, etc.) and
harmonic motion in the development section (the sudden move to G flat
major and then F sharp minor) and the rich ornamental figuration
throughout the movement (such as the little sixteenth-note violin
arabesque the first pops up at the end of the second bar) all act as
perfectly legible signatures.

The opening theme is as flexible a melody as one can imagine, its
rhythms frequently changing and its range of motion being all but
unrestricted. It might be argued that this tiny movement has no second
theme at all, for, although Schubert does move to the dominant and
proceed for ten-and-a-half bars, the melody used here seems just a new
spin on the ideas of the first theme, and the impression is as much a
coda as a new thought. ...

The following Andante (F major, 6/8 meter) is both graceful and
humorous, though a little cloud rises up as Schubert moves briefly
through a lugubrious F minor during the middle portion of the
movement. The violin provides an ornamented version of the opening
tune at the end of the movement.

During the trio section of the Minuet, the viola is allowed to take
center stage for a while, but as we move into the final Rondo, the
violin once again asserts itself as the real leader. Here all is in
good fun, and one senses that even the dramatic forte-pianos, bravura
triplets, and, as we move towards the end of the movement, mysterious
pianissimo sixteenth notes are to be taken more-or-less as musical
tongue-in-cheek. ~ Blair Johnston, All Music Guide

Franz Schubert, String Trio No. 1 in B flat Major, D471
D. 471, scored for the usual string trio ensemble of violin, viola,
and cello, is in effect a single-movement composition, as the
unfinished second movement can really be performed only as a novelty
item. The sole complete movement is an example of Classical
sonata-allegro form, marked Allegro by the composer. The opening theme
is given by the violin without introduction of any kind, to an
accompaniment of oscillating eighth notes in the viola and a long-held
B flat in the cello that soon enough breaks off to imitate a more
articulated idea played by the violin in the second bar of the theme.
After repeating this four-bar, pianissimo thought, Schubert moves on
to offer up some light-hearted triplets in the violin and a rich
twelve-bar transition, built around a B flat pedal-point in the viola
part, to the second theme. In this second theme area (in F major)
Schubert finds room for both some happy, spiccato mini-cadences and
some brilliant, forte descending scales in octaves. The coda to the
exposition is in three sections (the last of which is really a codetta
to the coda), the sum total of which take up just as much time as the
entire exposition-proper did.

Development is simple and straightforward in D. 471: most of the
fifty-four-bar development section is spent making one or another use
of the melodic gesture by which Schubert closed the final bar of the
exposition (the main themes don't really appear at all, save the first
theme in vague rhythmic outline and the second in one fleeting
reference). All is as a Classicist would expect it to be in the
recapitulation. The opening theme reappears unchanged, the second idea
is recast to suit the tonic key, and the same alternation of tonic
harmony with a pseudo-Neapolitan chord (as outlined by a quarter-note
arpeggiation in the cello, to which the violin and viola add the
piquant idea of an augmented sixth) that closed the exposition is
reused to bring the entire movement to a colorful final cadence.

Frédéric Chopin ( arr. Nathan Milstein)
Nocturne in C sharp Minor, op. posth.

Nathan Milstein (1904 - 1992) was a virtuoso violinist born in Russia.
He is widely considered one of the finest violinists of the 20th
century, well known for his interpretations of Bach's solo violin
works, and for works from the Romantic period. He was also known for
his long career: he performed at a high level of excellence in public
into his mid-80s, being forced to retire after suffering a broken
hand. Milstein transcribed Chopin's Nocturne in C sharp minor for use
as an encore piece. Judy Kang

Nocturne No. 20, Op. Posth. in C-sharp minor was composed by Frédéric
Chopin in the year 1830 for solo piano and dedicated to his older
sister, Ludwika Chopin. It was first published 26 years after the
composer's death. The composition is marked Lento con gran
espressione as the principal tempo and is written in common time.
It begins with a mellow introduction and the main theme starts from
bar 5 while the left hand ceaselessly plays quavers in arpeggios
throughout the duration of the piece in portamento slurs, thus imparting
a peaceful and continuous quality to the music. The theme then shifts
to a dreamy pianissimo in bar 21 and finally returns to the original theme
in bar 47 and concludes in C-sharp major. The themes from the middle
section resemble themes from Chopin's second piano concerto in F minor
which was composed around the same time (1830).

The Nocturne is featured in the Roman Polanski film The Pianist. It is
played twice (both incomplete) in the film by the protagonist Adrien
Brody as Wladyslaw Szpilman, both times at the recording studio at
Warsaw Radio at the beginning and the end of the film. Wikipedia

Joseph Haydn, Piano Trio in D minor, Hob. XV:23
Franz Joseph Haydn (31 March 1732 – 31 May 1809) was an
Austrian composer. He was one of the most prolific and prominent
composers of the classical period. He is often called the "Father of
the Symphony" and "Father of the String Quartet" because of his
important contributions to these genres. He was also instrumental in
the development of the piano trio and in the evolution of sonata
form.

Haydn spent much of his career as a court musician for the wealthy
Hungarian aristocratic Esterházy family on their remote estate.
Much of the music was written to please and delight a prince, and its
emotional tone is correspondingly upbeat.This tone
also reflects, perhaps, Haydn's fundamentally healthy and
well-balanced personality. Occasional minor-key works, often deadly
serious in character, form striking exceptions to the general rule.
Haydn's fast movements tend to be rhythmically propulsive and often
impart a great sense of energy, especially in the finales. Some
characteristic examples of Haydn's "rollicking" finale type are found
in the "London" symphony No. 104, the string quartet Op. 50 No. 1, and
the piano trio Hob XV: 27. Haydn's early slow movements are usually
not too slow in tempo, relaxed, and reflective. Later on, the
emotional range of the slow movements increases, notably in the deeply
felt slow movements of the quartets Op. 76 Nos. 3 and 5, symphony No.
102, and piano trio Hob XV: 23. The minuets tend to have a strong
downbeat and a clearly popular character. As early as Op. 33 (1781)
Haydn turned some of his minuets into "scherzi" which are much faster,
at one beat to the bar. Wikipedia

Gustav Mahler, Piano Quartet in A Minor
Mahler began studying at the Vienna Conservatory as a 15 year old
during the1875-76 academic year, and remained there for three years
while still enrolled as a high-school student at the Iglau Gymnasium.
He distinguished himself as a pianist at the Conservatory, and was
clearly being groomed for a career as a concert performer, but
the young Mahler soon turned to composition as his primary subject,
taking classes in harmony from Robert Fuchs and counterpoint with Franz
Krenn. Mahler was also a devotee of Bruckner’s music, and attended
Bruckner’s university lectures in Vienna without ever formally becoming
a pupil. He was enamored with Wagner’s music, andwas also a friend of
Hugo Wolf during his time at the Conservatory. Mahler’s first
compositions, which date from these early student years at
the Conservatory, are almost entirely chamber works. Most of them are
lost, and there is some confusion about the nature of these lost
works—many scholars believe, for example, that the lost Piano Quintet
listed as Mahler’s graduation piece, and for which he was awarded a
prize, is actually the Piano Quartet in A minor, entered wrongly in
the Conservatory’s own records. Adding to the confusion is the fact
that Mahler started many works during his student days, but finished
few of them, explaining to his friend and confidante at the
Conservatory Natalie Bauer-Lechner, that he always found himself
attracted to a newer style before finishing a work. As a student
composition, indeed the first composition that appears in Mahler's
works list, the Piano Quartet in A minor displays a certain tentative
confidence. Tentativebecause there was still so much for the young
composer to discover, and confidentbecause he had already assimilated
an extraordinary amount of compositional technique during his first
year of formal music instruction; he had come to the Conservatory
essentially self-taught.

The sonata structure of this one movement (sketches for a second
movement Scherzo survive, but are incomplete) demonstrates a
sympathetic knowledge not only of 19th-century form and compositional
style, but also the techniques of the great piano masters: Beethoven,
Schubert, Chopin, Schumann, and Brahms.While the key of A minor
would later symbolize for Mahler the “unconsciousanticipation of things
to come” (it is, for example, the key of his dramatic and sentimental Sixth
Symphony), it seems to have no obvious symbolic or referential
significance in this work. The opening of the piece introduces a Brahms-like
main theme of careful balance and lyricism. Mahler introduces a change
of tempo for the second key area—one of theseveral unusual elements
that mark this work as more than merely a competent student exercise.
The development section demonstrates his disciplined skill in motivic
development. As the change of tempo returns in the recapitulation,
Mahler pairs it with an unexpected harmonic excursion to the remote
key of F-sharp minor, and before themelancholy conclusion he includes
a mini-cadenza for violin. Devices such as theseenliven the conventional
formal plan.

This Quartet remained unpublished until 1964, but it has since been
recorded several times. It has also directly inspired two compositions
by Alfred Schnittke: thesecond movement of Schnittke’s Concerto grosso
No. 4/Symphony No. 3 (1985), and hisPiano Quartet [after sketches by
Mahler] (1989).
