19: A Data Melody is an audio piece demonstrating the rate of Covid 19 cases and deaths, reported daily throughout the Republic of Ireland, over the course of a year through sound. The 11th of March 2020 saw the first Covid 19 related death in Ireland. On this day, the World Health Organisation announced an official global pandemic. Using case and death figures, released by the Irish Government daily, this piece allocates musical notes to corresponding numbers composing a melody consisting of 365 notes. An acoustic timeline of transmission in Ireland over a year develops. As the rate of cases and deaths increase octaves change creating deeper notes, documenting a timeline of covid 19 through data conversion into musical notes.
