Lieder ohne Worte
The eight volumes of "Songs Without Words", each consisting of six songs (), were written at various points throughout Mendelssohn's life, and were published separately. The piano became increasingly popular in Europe during the early nineteenth century, when it became a standard item in many middle-class households. The pieces are within the grasp of pianists of various abilities and this undoubtedly contributed to their popularity. This great popularity has caused many critics to under-rate their musical value.
