In Hong Kong, the gap in music education access between children from affluent and grassroots families is pronounced. To address this, we present "Music Corner," a prototype of a gesture-based rhythm game designed to democratise music education through digital innovation. Utilising mobile technology and machine learning, this study explores the feasibility of an engaging, accessible, and cost-effective platform for music learning. It leverages the Solfege Hand Signs, used by Hong Kong's primary music education, by transforming them into a game where players interact with musical notes through intuitive gestures. This initiative aims to bridge the educational divide, fostering an inclusive environment where children of all socioeconomic statuses can nurture their musical abilities. The prototype features three game modes to cater different learning objectives. With a focus on interactive technology, "Music Corner" stands as a testament to the potential of gamification in enhancing music literacy, making education more inclusive and enjoyable.
