Tremolo: A Podcast Drama by Lisa Parry

Tremolo, launched March 3rd, is a podcast drama produced by Illumine Theatre in partnership with Wales Gene Park and Theatr Genedlaethol Cymru, supported by the Genetics Society. Written by Cardiff-based playwright Lisa Parry (Co-director of Illumine Theatre), this powerful podcast gives an insight into the question of whether to have genetic testing and how one family copes with the diagnosis that may be hidden in their genes.  

Tremolo is presented through the eyes of Harri, a caring teenage boy. Like many youngsters who have just completed their final A-Level exams, Harri is excited about the future; inter-railing with his friend and then off to Uni to follow his dream of becoming a neurosurgeon. Suddenly, his world is turned upside down when his loving mother is diagnosed with eFAD – early onset familial Alzheimer’s disease. Due to genetics, there’s a 50% chance that he and his younger sister Gwenllian may have it too. As the play develops, we learn about the early signs of the condition. Through Harri’s eyes we also learn about the effect of this on family relationships, financial pressures, daily life and dreams. 

Tremolo is aimed primarily at students aged 16+, but also available to the wider public. It is available in both English and Welsh to listen and download via platforms including Spotify, Apple Podcasts, AM & on Theatr Genedlaethol’s website. The podcast series will also feature episodes from the drama’s creative team discussing the themes of the play, as well as contributions from genetics specialists. 

The drama is also accompanied by an education pack for schools & colleges aimed at year 12/13 students which contains creative content and scientific content. Teachers/educators can get a copy of the pack by emailing
