Octet (Mendelssohn)

Mendelssohn wrote his octet and gave a signed score to his friend and violin teacher as a birthday present. Rietz copied parts from the score to use for the premiere. The string octet was a fairly new genre of chamber music at the time, the most widely known genre of chamber music still being the string quartet. The genre was rapidly gaining popularity among other composers. When Mendelssohn composed his octet, it was a rather new genre, and he may have been inspired by Louis Spohr's Double Quartet in D minor, Op. 65. But Spohr's double quartet was written with the two quartets playing apart from each other; Mendelssohn's octet is an undivided ensemble. In the score, Mendelssohn wrote that the piece should "be played by all the instruments in the style of a symphony." ==Structure==

The work consists of four movements: A typical performance of the work lasts around 30 minutes, with the first movement usually comprising roughly half of this. All four movements are in sonata form. I. Allegro moderato ma con fuoco : \header { piece = \markup \bold \large "First theme" } \relative c' { \tempo "Allegro moderato ma con fuoco" \tempo 4 = 144 \key es \major \time 4/4 \clef treble \set Staff.midiInstrument = "violin" \bar "" r4 r8 g\p (bes es g es' | bes4.) bes,8( es g bes g' | es4.) es,8\ The first movement's first theme begins above tremolo string accompaniment before being restated in the lower strings. A prolonged climax in the development builds from quiet whole notes into a flurry of sixteenth notes. Fragments of this movement recur in the finale, as a precursor to the "cyclic" technique later 19th-century composers employed. The entire work is also notable for its extended use of counterpoint, with the finale, in particular, beginning with an eight-part fugato. In this section, Mendelssohn quotes the melody of "And he shall reign forever and ever" from the "Hallelujah Chorus" of Handel's Messiah. IV. Presto The Presto begins with a fugal figure transferred across the eight instruments, from the second cello to the first violin, before being contrasted with an octave motif. In the development section, Mendelssohn reprises the scherzo's main theme in sequence. ==Instrumentation==

The original score is for a double string quartet with four violins and pairs of violas and cellos. Mendelssohn wrote in the score, "This Octet must be played by all the instruments in symphonic orchestral style. Pianos and fortes must be strictly observed and more strongly emphasized than is usual in pieces of this character." He also transcribed the piece for piano duet with violin and cello ad. lib. and orchestrated the third movement (with alterations) as an alternative third movement to his Symphony No. 1 in C minor. The piece is sometimes played by full string sections using more players for each part as well as a double bass that usually doubles the second cello part an octave lower. Arturo Toscanini created such a version for a performance with the NBC Symphony Orchestra in 1947. In 2009, conductor Yoon Jae Lee made a transcription of the first, second, and last movements for full orchestra. ==References==
