3:16 EnglishThe Whole Horn, Room by Room: A Band Director Walks You Through All 18 RoomsAll 18 rooms, narrated in English.

All nine languages

In your language

30 languages, one short film each

A teacher picks an exercise, a key and a tempo, sends one link, and every student opens it on their own instrument. Each language has its own page, with its film and the store links. The Arabic, Chinese, French, German, Italian, Japanese, Portuguese and Spanish pages carry the full tour as well. Chinese is listed in both scripts, Simplified and Traditional; the film is the same one. The app itself is in English; the notation is the same everywhere.

This film has no English version; for English, watch the tour above.
