Felix Mendelssohn's Violin Concerto in E minor, Op. 64, is his last concerto. Well received at its premiere, it has remained among the most prominent and highly-regarded violin concertos. It holds a central place in the violin repertoire and has developed a reputation as an essential concerto for all aspiring concert violinists to master, and usually one of the first Romantic era concertos they learn. A typical performance lasts just under half an hour. Mendelssohn originally proposed the idea of the violin concerto to Ferdinand David, a close friend and then concertmaster of the Leipzig Gewandhaus Orchestra. Although conceived in 1838, the work took another six years to complete and was not premiered until 1845. During this time, Mendelssohn maintained a regular correspondence with David, who gave him many suggestions. The work itself was one of the foremost violin concertos of the Romantic era and was influential on many other composers. Although the concerto consists of three movements in a standard fast–slow–fast structure and each movement follows a traditional form, it was innovative and included many novel features for its time. Distinctive aspects include the almost immediate entrance of the violin at the beginning of the work (rather than following an orchestral preview of the first movement's major themes, as was typical in Classical-era concertos) and the through-composed form of the concerto as a whole, in which the three movements are melodically and harmonically connected and played attacca (each movement immediately following the previous one without any pauses). Many violinists have recorded the concerto and it is performed in concerts and classical music competitions. It was recorded by Nathan Milstein and the New York Philharmonic as an album and released as the first LP record upon the format's introduction in 1948. History Following his appointment in 1835 as principal conductor of the Leipzig Gewandhaus Orchestra, Mendelssohn named his childhood friend Ferdinand David as the orchestra's concertmaster. The work's origins derive from this professional collaboration. In a letter dated 30 July 1838, Mendelssohn wrote to David: "I should like to write a violin concerto for you next winter. One in E minor runs through my head, the beginning of which gives me no peace." The concerto took another six years to complete. There are many possible reasons for the delay, including self-doubt, his third symphony and an unhappy period in Berlin after a request from King Frederick William IV of Prussia.
