Complementary Files

A companion to the book, offering simple interactive tools that let you hear, see, and explore the foundations of sound. Each page invites you to experiment with intervals, strings, modes, and ancient melodies—where theory becomes experience.

The Complementary Files section provides the complete frequency–length tables and the downloadable musical exercises used throughout the book.

Where the book introduces concepts, these pages let you try them. The monochord, the ancient modes, the geometry of intervals—they become things you can touch, hear, and explore at your own pace.
