Ilona Sie Dhian Ho is professor of Violin at the Royal Conservatoire and chamber music player at several festivals. She has given masterclasses in Europe, USA and China. She is jury member of several violin competitions and since 2018 member of the artistic board of Dutch Violin Competitions.

In 2013 she started an outreach project, Music Around the Corner, in which she developed ways to perform classical music in the Morgenstond district, The Hague. With students she formed a ‘district orchestra’, Orkest Morgenstond. This orchestra collaborates with local partners to create tailored performances. To generate a better understanding of presentation techniques that increase the impact of classical music, she extended these practice-based studies to a scientific research project. She started The Classic Expression Research group in which musicians of The Royal Conservatoire and scientists of Leiden University collaborate. By designing controlled experiments in the Classic Express, a mobile concert truck, she will analyze the impact of presentation techniques that were developed in Morgenstond. The aim is to provide insights in how to reach specific groups within the population, as well as to reflect on the artistic consequences of such presentation techniques. The first study on story telling in musical performances for children will take place in 2021.
