'Lieder ohne Worte' is extraordinary in a number of ways. In general it announces both the classical revival and the Aesthetic Movement, and is a perfect marriage of the principles of both. Leighton's classicism is imaginative, unlike the everyday literalness of Alma-Tadema for example, and the picture evokes a delicate poetic mood. It is painted in carefully controlled harmonies of colour and the frame is consciously designed, probably by the artist, to relate to the painting and so create a unified decorative whole. The musical title evokes one of the basic principles of the Aesthetic Movement, that painting can function, like music, purely in an abstract and evocative way through relationships of colour and form.
Lieder ohne Worte is in fact the title of a group of forty-eight short piano pieces by Mendelssohn which were well known and popular in England. The 'Songs without Words' that the young woman is hearing are, of course, the musical splash of the fountain and the song of the bird above her.
