The student's voice manual, and the first title on this shelf that trains the instrument instead of the speech. Thirty days, ten minutes a day. It opens with the diagram: air is the power, the folds are the source, the mouth and the face are the shape. Then it trains all three. Breath deep enough to finish a sentence with the power you started it with. Resonance that buys volume without pushing. Articulation that gets consonants to the back of a room with bad acoustics. A volume dial calibrated against a real listener, so "speak up" becomes a number instead of an opinion. Pitch range, so the sentence that matters can sound different from the one before it. The face as the tone control, which is the fastest change available to any speaker. And the filler repair that swaps the "um" for a pause of the same length, because the hole is what the "um" was covering. Twenty-one named drills with run times, indexed at the back so a parent or a coach can call for one by name. A ten-minute warm-up in fixed order, on a tear-out card. A thirty-box log filled in pen. A three-pass tape review with verdicts banned and observations only. And two recordings, day one and day twenty-eight, so the argument gets settled by the tape.

Your license
Household license. Print the tear-out warm-up card as often as it wears out.
This is the course. The cohort is the room. The book will teach your student what to do. It cannot give them a room of peers, a live audience, and a coach watching their hands.
A Rhetrix cohort seat is $650. One-on-one coaching is $200 to $250 per session. See open cohorts
About the 2026-27 Edition
This is the 2026-27 Edition. Every Rhetrix title is dated, because every Rhetrix title gets rebuilt. Each summer we take a year of real families running these pages, cut what did not earn its place, and ship a new edition with new material. Your purchase is this edition, in full, for good, with any correction we publish to it at no charge. Next summer's edition is a new book with new work in it, sold on its own. We would rather earn the next one than hand it over.
