Thisstudy demonstrates that autobiographies are far more than individual life-stories. Autobiographies of couples in particular testify to the interfaces of togetherness in life and writing. They provide a marvellous opportunity to examine the life and writing of couples as a duet and to perceive relational dimensions of life in creative artistic processes as an ethical and aesthetic factor. The present study traces the complex relational network of autobiographies using the example of the well-known Spanish writing couple of María Teresa León and Rafael Alberti. María Teresa Quirós Fernández reveals how, beyond the individual characters of the autobiographies, there is a web spun between both authors and their texts in their autobiographical writings which provides space for astereophonic autobiography.
