""Improvisation is spontaneity in music. It can be beautiful, uplifting, and unnerving all at the same. It happens instantaneously, in a unique context, with ideas never to be performed the same way again. It can be the result of years of practice or an unexpected reaction to a collaborative musical moment. As Spolin so eloquently explains, it provides musicians with an opportunity to explore a musical situation where boundaries can be stretched and new ideas can be enacted. Out of these experiences comes a sense of freedom and agency that can inspire a young musician. We have seen the power of these experiences in our own students, and we hope to foster those same experiences for students through the teaching approaches and activities discussed in this book. Where do improvised musical moments live in the typical music curriculum? We know that it is a challenge to incorporate improvisation on a consistent basis. As new music teachers, we often incorporated improvisation as a culminating experience at the end of a unit, or we saved improvisation experiences until concerts were completed. Improvisation did not seem like something that we could address year-long when the demands of content or performance were so great. It changed our teaching when we realized that we could integrate music improvisation activities consistently into the ensemble or music classroom curriculum. Furthermore, we realized that we did not need to hit the ""pause"" button on concert preparation to work on an improvisation unit, both repertoire and improvisation could advance our students' performance abilities. A music teacher can do this in a group setting by tapping into students' diverse personalities and voices. Improvisation is often framed as an independent enterprise, but an eclectic group of students provides boundless opportunities for rich and varied musical collaboration. Moreover, the teacher can be essential in facilitating vibrant group improvisation experiences. There is something different that happens in musical development when we set up opportunities for students to make spontaneous musical choices for themselves. Students begin to listen differently, watch differently, feel differently, and perform differently if we give them the space to stretch musical boundaries and create their own musical ideas. How do we know that students change when they begin to improvise? By focusing on musical elements in improvised activities such as melody, harmony, rhythm, timbre/texture, articulation, and dynamics consistently over time-we have seen students transform. By grounding musical improvisation in these musical elements, students can begin to connect and produce music that reflects layered levels of musical understanding. Furthermore, when lessons are exploratory, interdisciplinary, or inspired by principles in various genres students will experience more fluid musical interactions, become more attuned to their neighbors, and more open and adaptive to musical ideas. This book is designed to provide an accessible approach to including musical improvisation in the large ensemble and classroom setting. It is largely based on the transformative musical experiences we have had with students when we began incorporating improvisation into our teaching. The spontaneous and unpredictable nature of musical improvisation can be challenging, but the rewards far outweigh any momentary trepidation that teachers and students might feel. The pedagogical suggestions and lesson plans presented will make the benefits of teaching and learning improvisation clear and provide an approach that is adaptable and manageable for music teachers working with large numbers of students. In doing so, teachers will learn more about students' musical thinking and will enhance musicianship skills for their entire ensembles. The 2014 National Music Standards call for music teachers to engage students in the musical process of creation and describes improvisation as an integral experience. Yet we know, many teachers, particularly in large ensembles and classroom settings, still struggle to find ways to make improvisation a reality (Bernhard, 2013; Bernhard & Stringham, 2016; Schopp, 2006). The book is framed around practical and flexible ideas for implementing improvisation activities. The lesson activities borrow broad principles from different musical styles and genres to provide a variety of improvisation settings and appeal to diverse student interests. Many activities are exploratory in nature allowing students to play and respond to each other while also focusing on core musical elements such as melody and rhythm. Interdisciplinary teaching approaches and resources are suggested throughout many of the lessons to enhance creative expression and build connections between the arts. Lessons include learning objectives, detailed procedures, assessments, benefits, recordings, and mp3 examples. ""--
