The Hollywood String Quartet (HSQ) was an American string quartet founded by violinist/conductor Felix Slatkin and his wife cellist Eleanor Aller. The Hollywood String Quartet is considered to be the first American-born and trained classical music chamber group to make an international impact, mainly through its landmark recordings. These recordings have long been regarded as among the most outstanding recorded performances of the string quartet repertoire.

Album leaf is the title of numerous minor compositions by a wide variety of classical composers. It also appears in the French version, Feuille d'album or Feuillet d'album; the German version Albumblatt (pl. Albumblätter); the Russian version Листок из альбома (pl. Листки из альбома); the Spanish and Latin-American versions Hoja de álbum; and other languages. Many of these pieces are for piano solo, but the title has also been used for other instrumental pieces in the salon music genre, and for vocal pieces. They tend to be short, pleasant, and not particularly demanding on the performer. There is no standard form or structure; the title Album leaf is quite arbitrary, and these pieces could just as easily have been called Prelude, Impromptu, Romance, Humoresque or other names. Originally, the term "Album leaf" was used for pieces written in dedication to a friend or admirer, to be inserted into their album or autograph book, and not intended for publication. It later lost any association with a particular dedicatee.

The Silesian String Quartet is a string quartet founded in 1978 by the graduates of the Karol Szymanowski Academy of Music in Katowice, Poland. Its current members are: Szymon Krzeszowiec (violin I) Arkadiusz Kubica (violin II) Łukasz Syrnicki (viola) Piotr Janosik (cello)

The viola ( vee-OH-lə, () Italian: [ˈvjɔːla, viˈɔːla]) is a string instrument of the violin family, and is usually bowed when played. The viola is slightly larger than the violin and has a lower sound. Since the 18th century, it has been the middle or alto voice of the violin family, between the violin (which is tuned a perfect fifth higher) and the cello (which is tuned an octave lower). The strings from low to high are typically tuned to C3, G3, D4, and A4. In the past, the viola varied in size and style, as did its names. The word viola originates from the Italian language. The Italians often used the term viola da braccio, meaning, literally, 'of the arm'. "Brazzo" was another Italian word for the viola, which the Germans adopted as Bratsche. The French had their own names: cinquiesme was a small viola, haute contre was a large viola, and taile was a tenor. Today, the French use the term alto, a reference to its range. The viola was popular in the heyday of five-part harmony, up until the eighteenth century, taking three lines of the harmony and occasionally playing the melody line. Music notation for the viola differs from most other instruments in that it primarily uses the alto clef. When viola music has substantial sections in a higher register, it switches to the treble clef to make it easier to read. The viola often plays the "inner voices" in string quartets and symphonic writing, and it is more likely than the first violin to play accompaniment parts. The viola occasionally plays a major, soloistic role in orchestral or chamber music. Examples include the symphonic poem Don Quixote, by Richard Strauss, the 13th Quartet by Dmitri Shostakovich, and a symphony with a main viola line: Harold en Italie, by Hector Berlioz. In the earlier part of the 20th century, more composers began to write for the viola, encouraged by the emergence of specialized soloists such as Lionel Tertis and William Primrose. English composers Arthur Bliss, Edwin York Bowen, Benjamin Dale, Frank Bridge, Benjamin Britten, Rebecca Clarke and Ralph Vaughan Williams all wrote substantial chamber and concert works. Many of these pieces were commissioned by, or written for, Tertis. William Walton, Bohuslav Martinů, Tōru Takemitsu, Tibor Serly, Alfred Schnittke, and Béla Bartók have written well-known viola concertos. The concerti by Bartók, Paul Hindemith, Carl Stamitz, Georg Philipp Telemann, and Walton are considered major works of the viola repertoire. Hindemith, who was a violist, wrote a substantial amount of music for viola, including the concerto Der Schwanendreher.

A violin concerto is a concerto for solo violin (occasionally, two or more violins) and instrumental ensemble (customarily orchestra). Such works have been written since the Baroque period, when the solo concerto form was first developed, up through the present day. Many major composers have contributed to the violin concerto repertoire. Traditionally a three-movement work, the violin concerto has been structured in four movements by a number of modern composers, including Dmitri Shostakovich, Igor Stravinsky, and Alban Berg. In some violin concertos, especially from the Baroque and modern eras, the violin (or group of violins) is accompanied by a chamber ensemble rather than an orchestra—for instance, in Vivaldi's L'estro armonico, originally scored for four violins, two violas, cello, and continuo, and in Allan Pettersson's first concerto, for violin and string quartet.

Dmitri Shostakovich typically catalogued his compositions and occasionally his arrangements of other composers' music with opus numbers. He began this practice with the early Scherzo in F-sharp minor and continued until the end of his life. Nevertheless, most of his juvenilia, unfinished works from his artistic maturity (such as the operas Orango and The Gamblers), and numerous completed works were left unnumbered. There were also instances when Shostakovich took an opus number assigned to one work, then gave it to another, or was undecided about the numbering of a finished composition. Further complicating the matter was an error he committed in compiling his own music in the 1930s. This led to his soundtracks for The Youth of Maxim and Girl Friends sharing the same opus number.

Johannes Brahms (; German: [joˈhanəs ˈbʁaːms] ; 7 May 1833 – 3 April 1897) was a German composer, virtuoso pianist, and conductor of the mid-Romantic period. His music is noted for its rhythmic vitality and freer treatment of dissonance, often set within studied yet expressive contrapuntal textures. He adapted the traditional structures and techniques of a wide historical range of earlier composers. His œuvre includes four symphonies, four concertos, a Requiem, much chamber music, and hundreds of folk-song arrangements and Lieder, among other works for symphony orchestra, piano, organ, and choir. Born to a musical family in Hamburg, Brahms began composing and concertizing locally in his youth. He toured Central Europe as a pianist in his adulthood, premiering many of his own works and meeting Franz Liszt in Weimar. Brahms worked with Ede Reményi and Joseph Joachim, seeking Robert Schumann's approval through Joachim. He gained both Robert and Clara Schumann's support and guidance. Brahms stayed with Clara in Düsseldorf, becoming devoted to her amid Robert's insanity and institutionalization. The two remained close, lifelong friends after Robert's death. Brahms never married, perhaps in an effort to focus on his work as a musician and scholar. He was a self-conscious, sometimes severely self-critical composer. Though innovative, his music was considered relatively conservative within the polarized context of the War of the Romantics, an affair in which Brahms regretted his public involvement. His compositions were largely successful, attracting a growing circle of supporters, friends, and musicians. Eduard Hanslick celebrated them polemically as absolute music, and Hans von Bülow even cast Brahms as the successor of Johann Sebastian Bach and Ludwig van Beethoven, an idea Richard Wagner mocked. Settling in Vienna, Brahms conducted the Singakademie and Gesellschaft der Musikfreunde, programming the early and often "serious" music of his personal studies. He considered retiring from composition late in life but continued to write chamber music, especially for Richard Mühlfeld. Brahms's contributions and craftsmanship were admired by his contemporaries like Antonín Dvořák, whose music he enthusiastically supported, and a variety of later composers. Max Reger and Alexander Zemlinsky reconciled Brahms's and Wagner's often contrasted styles. So did Arnold Schoenberg, who emphasized Brahms's "progressive" side. He and Anton Webern were inspired by the intricate structural coherence of Brahms's music, including what Schoenberg termed its developing variation. It remains a staple of the concert repertoire, continuing to influence composers into the 21st century.

A string quintet is a musical composition for five string players. As an extension to the string quartet (two violins, a viola, and a cello), a string quintet includes a fifth string instrument, usually a second viola (a so-called "viola quintet") or a second cello (a "cello quintet"), or occasionally a double bass. Notable examples of classic "viola quintets", in four movement form include those of Wolfgang Amadeus Mozart. Other examples were written by composers including Johannes Brahms and Felix Mendelssohn. A famous "cello quintet" is Franz Schubert's Quintet in C major. Antonín Dvořák's Quintet Op. 77 uses a double bass, and Mozart's famous Eine kleine Nachtmusik may be performed with this instrumentation (the double bass being optional). Alternative additions to a string quartet include clarinet or piano (see clarinet quintet, piano quintet). A more unusual form of string quintet is the violin quintet composed of 3 violins, a viola and a cello (thus, a string quartet with an additional violin). Besides string quartets and quintets, other closely related chamber music genres include the string trio, and the string sextet. The term string quintet may also refer to a group of five players that specializes in performing such works. The ensemble was standard in 17th century Italy and can be seen as early as 1607 in Claudio Monteverdi's opera, L'Orfeo.
