Teaching is a vital part of Keys of Change’s activities, and we are very lucky to work with a group of dedicated and inspirational musicians, all of whom are enthusiastic supporters of the belief that music can change the world. 

Based in different corners of the world, most have experience of playing in some of the best orchestras and musical groups world-wide, and all, critically, a passion to pass on their knowledge and experience by teaching young musicians in less fortunate circumstances. Our teachers think nothing of travelling across continents to participate in music camps in Ghana, Mexico or India, or of getting up early to give a virtual lesson in a different time zone. Their dedication, professionalism and enthusiasm transmit themselves to the young musicians we support and enable them to reach heights they had never dreamed of attaining.
