Musical play is a very important part of The Music Work's current Youth Music-funded project “Playing Around Sound”. Through an action research approach we are working with deaf children aged 8 or under, their siblings and their parents, in order to find out what approaches to active music-making “work”. We aim to develop a pedagogy for this audience of carefully chosen repertoire, musical instruments and ways of presenting an environment that is conducive to musical play.
