Clarke wrote a whole series of Lullabies
between 1909 and 1918, and the subject-matter of Morpheus
therefore puts it into the same catagory. This Lullaby
is the first, dated 1909, and is amongst the earliest of her instrumental works. The gentle, abstract idea of the rocking or singing of a child to sleep obviously appealed strongly to her romantic nature and her particular mode of expression in music.
