We should not be deceived by the high opus number 110: the popular D major Sextet was written in 1824 and, like many other works by Mendelssohn, first discovered posthumously. It was both published and given its world premiere in 1858. The 15-year-old composer repeatedly and successfully experimented with the genre of the concerto for solo instrument and orchestra, and his efforts can be seen quite strikingly in his chamber works for larger scorings as well. Upon closer examination, the Sextet turns out to be a piano concerto in disguise, with a most unusual string accompaniment. The respective distribution of the roles is clearly recognizable in the score. The stylistic influences of Mozart, Beethoven and Hummel clearly shimmer behind the masterful formal design of the work. The new edition of the score and parts is based on the corresponding volume of the Leipzig Mendelssohn Complete Edition Seris III Vol. 11.
