Helen Thomas developed an interest in Stockhausen as a teenager when she came across a score of YLEM at the Henry Watson Music Library in Manchester. Undergraduate music studies at the University of York led to a decade promoting contemporary British repertoire for Oxford University Press then, following the birth of two sons, work in the Further Education sector. In 2008 Helen gained a Masters with distinction in Music since 1900 from Liverpool Hope University, an award that acknowledged her research into morphologies of time in Stockhausen’s Montag. This thesis was subsequently published as an article in the journal Tempo. In personal correspondence Stockhausen wrote: “your text is true and beautiful. It is the first text on Licht to my knowledge which combines the Spiritual and Materialistic Parameters”. Helen is currently completing a doctorate at Lancaster University researching metaphors of time in 1960s Modernist repertoire including a case study of Stockhausen’s Klavierstuck X. She now works as a freelance lecturer, writer and oboist.
