As part of a series of coordinated diction manuals and anthologies, the fully reproducible Teachers' Supplementary Materials for Gateway to German Diction helps students to move beyond diction to clear understanding and authentic style. Supplemental instructional, review, and testing materials are included in the book. Thomas Hampson says the series not only achieves an excellent study of the tools for proper translation and diction, it goes much deeper and more importantly to the teaching of musical and poetic expression from the inner side of the language.
