It is fully justifiable to claim that Felix Mendelssohn Bartholdy is the foremost German church-music composer of the 19th century. This is due above all to his many sacred vocal works in various formats and to his many compositions for the organ.
The most important among them are without a doubt the six Organ Sonatas op. 65, which have become an indispensable component of the general organ repertoire. The spark was possibly lit by two English publishers who – thrilled by Mendelssohn’s organ playing – ordered various organ pieces in different formats from the composer.
These pieces were written in 1844/45 and then collated to form six organ sonatas. However, they did not constitute sonatas in the strict sense of the word, but rather suites. In their multiplicity of forms – reminiscent of chorales and lieder, of polyphonic and virtuoso pieces – they form a genuine compendium of organ playing.

Critical Commentary
About the composer

Felix Mendelssohn Bartholdy
A German composer, conductor, pianist, and organist who already numbered among the most important composers in Europe during his lifetime. While still young he found a unique tonal language. Reflected in his oeuvre, which spans all genres, are the contradictory tendencies of the age – Classicism and Romanticism. His endeavors over the course his life to perform the works of Johann Sebastian Bach led to a “rediscovery” of that composer which continues unabated. His intensive engagement with Bach and his counterpoint influenced his own compositional technique.
