General Preparation Clean tools: Scrub each straw end-to-end with the included brush and a drop of mild soap, rinse in hot water, and air-dry completely before use. Find resting larynx: Pant like a small dog, then a big dog; your resting larynx sits between those two positions. Seal and phonate: Place the straw snugly between your lips (no air leaking through mouth or nose), and phonate steady “whoops” or hum-like vowel sounds into the straw . 1. 5″ × 3 mm Straws (Higher Resistance; Short Length) When to use: Initial warm-ups to activate vocal fold closure and proprioception. Cool-downs after heavy voice use or gigs to relieve tension. Protocol: Phonate a comfortable mid-range vowel for 15 sec, rest 5 sec; repeat 3 times . Do low-to-high and high-to-low pitch glides (10–15 sec each) to explore range without strain . 2. 7″ × 3 mm Straw (Higher Resistance; Increased Back-Pressure) When to use: After warm-up, to deepen semi-occluded back-pressure for balanced vocal fold vibration. To strengthen head-voice coordination and mix voice transitions. Protocol: Phonate sustained pitches (10–15 sec) on “oo” or “ee,” focus on steady airflow and minimal throat tension . Integrate simple singing phrases or scales, keeping the straw just outside the lips, no deep insertion. 3. 7″ × 6 mm Straw (Lower Resistance; Long Length) When to use: Range extension and dynamic control—ideal for exploring higher pitches with less back-pressure. Rehabilitation or recovery when voice feels fatigued—reduces phonation threshold pressure. Protocol: Start with gentle glides at comfortable pitches (10–15 sec), noticing ease of phonation . Move to longer phrases or soft singing through the straw, ensuring a relaxed larynx and consistent airflow
