Sound Differentiation is a motivational, time-saving supplemental resource that provides differentiated parts for 15 well-known tunes---perfect for a variety of teaching situations, including odd or incomplete instrumentation, or when working with a mix of ability levels. The arrangements in this collection are ready for use in an adaptable format with identical parts for all instruments. The featured parts are tune, bass line, harmony, and variation, and each one can be assigned to your choice of soloists, instrument sections, or difficulty-leveled groupings of students of both like-instrumentation or mixed-instrumentation. The difficulty of each piece progresses throughout the book. Here are just some of the ways to differentiate with Sound Differentiation: * Group students into 3 categories based on skill level and assign level-appropriate parts. * Customize each arrangement by choosing the order in which students play each line of the song. * Teachers may assign a new line order using the blank Teacher Order column.
