Tertiary Education Expenditures

gavcloud - Tertiary Education Expenditures, 2024, color video with sound, 90 seconds

Tertiary Education Expenditures is a 90-second audio/visual piece that uses data sonification as its principal process. Utilizing UNESCO Institute of Statistics data for number of people of any age group who are enrolled in tertiary education expressed as a percentage of the total population from 1970-2022, TEE creates linear isomrophic mappings between musical pitch and alphabetically ordered countries and their respective data-points, each pitch representing a single year's percentage of enrollment. Rhythmical variety is established when the percentage of enrollment is very low, which causes rhythmic 'rests' in the melody to occur below a certain threshold. The pitch information is scaled to the Euler microtonal tuning.
