For an arranger, the study of texture provides a solid foundation to build your arrangements on. Each different type of musical texture has a variety of options that can be used expressively, but the most varied and most used of these textures is homophony. Your music will reach new creative heights once your homophony moves beyond simple “stock” accompaniment patterns and introduces the use of counter melodies, call and response, and harmonized lines.
Play through (or listen through) your theme and variations. Explore for areas that you can expand beyond accompaniment patterns and use texture to add variety and interest throughout your work.
