This arrangement of the National Anthem allows you to choose the instrumentation that best suits your ensemble. There are 4 parts and each part is transposed for various instruments. You can perform the piece with 2 parts (part 1 and 4), 3 parts (parts 1, 2 and 4), and 4 parts (all 4 parts). This arrangement is great for young and developing ensembles. I removed the fermatas at the end of the piece, and wrote it in a way to give the illusion of fermatas. This arrangement is also great for ensembles with limited numbers, those lacking enough of specific instruments, or for small chamber ensembles.
