This chapter examines the use of writing as a tool for learning and retention in the choral rehearsal. Writing ensures a level of participation in analytical exercises not guaranteed during discussions, where students can easily disengage without notice. This chapter also notes the opportunity that writing can afford to the more introverted students, or those less likely to speak up to share their insights. The author suggests numerous ways to incorporate writing into various points of a rehearsal, such as during the opening minutes, at midway points, as exit cards at the conclusion, those occasions when singers need to sit out, or as journal entries written during or outside of rehearsal. No matter the type of writing activity, whether reflective, predictive, analytical, or summative, the chapter investigates exercises that keep students mentally engaged, encouraging creative and active participation in rehearsal.
