Sylvia Forster’s painting was ultimately a private matter and could be described as a personal discourse with herself. She said of her own practice ‘I find satisfaction in assembling a variety of items into a whole. My paintings are not meant to be symbolical in any way. I find that objects with elements of design in them i.e., spots and stripes, and in the case of stringed instruments curves as well, making an interesting beginning to build on. I play about with the material, to the form and colour until I feel satisfied with the whole – occasionally, one seems to evoke sound in the painting’.
In spite of the private nature of her work, Forster did exhibit her paintings at the Royal Academy in 1963, 1964, and 1965.
