Instrumentation: for soprano, flute and violoncello

Texts: James Joyce

‘Tantris’ comes from a section of ‘Finnigan's Wake’ by James Joyce. Both the soprano and the instruments are set in a linear, contrapuntal fashion. Smaller intervals predominate in the soprano part, which circle around a pivotal central tone, often becoming enriched with the use of quartertones. Only in the setting of certain important words are bigger leaps used.

The intensity of E. E. Cummings' texts is reflected in very expressive musical phrases. The handling of melody is similar to that of 'Tantris'. The realisation of intricate sound details is left to the possibilities of the chosen instruments and the musical imagination of their interpreters.
