Big band
Big band music is particularly important for jazz education because it introduces a number of new forums for the furthering of jazz music. The first such forum is the arranger. With the emergence of big bands arose a need for more detailed and thorough arrangements. Arrangers helped to standardize big band vocabulary. With the arranger, jazz began to mature from its roots as an exclusively aural art form. The arranger helped to introduce new influences, especially Impressionist Music during the big band era.
