'It's OK' is one of a series of booklets which develop activities in a progressive way. They suggest ideas for collaboration between teachers and other school staff and Visiting Musicians. The purpose of these activities is for children to develop focused listening and a musical vocabulary, including: - the ability to recognise and distinguish between musical elements and terminology, - their emotional response to music, - recognition of music from different times and places, - responding to different moods and characteristics in music, - recognition that music can be used to achieve particular effects, - giving children a chance to develop and explain preferences in their own listening. This series of books is written primarily with the 'generalist' music teacher in mind, although specialists/coordinators may appreciate ideas they can add to their music-teaching repertoire. The materials also work well in a Professional Development context.
