Musical Impressionism with Debussy | Timbre, Whole-Tone Scale & Parallel Chords | Complete High School Music Unit

Musical Impressionism with Debussy is a complete, no-prep upper-secondary music unit: six lessons with five differentiated worksheets and full answer keys, three student reading texts, a detailed teacher lesson plan and an editable presentation — print and digital, ready to teach.

Debussy did not decorate tonality — he replaced its centre of gravity. This unit shows how the whole-tone scale, pentatonicism, modes and parallel chords dissolve functional pull and make timbre itself carry the form, through “Voiles”, “La Mer” and the “Prélude à l'après-midi d'un faune”.
