EXERCISE GUIDE

Vocal exercise guide

Choose a comfortable range and read the purpose and precautions before starting. These are practice templates to review with your teacher, not medical treatment.

Setting your range

Male (C3–G4), Female (C4–G5), Low, Mid and High are starting points, not voice classifications. Set notes you can sing comfortably today. Your transition note only changes pattern placement; it is not automatically measured.

Using the piano

Wait for four count-in beats, then sing the chosen syllable along with the displayed pattern. Rest between patterns. Pause before changing tempo. The piano provides pitch and timing, not an example of vocal technique.

01

Lip trill

Connect notes with a light voice and vibrating lips.

Approximate difficulty: Introductory

Before you start: You can vibrate your lips at low volume.

Goal: Sing five notes up and down without forcing air.

Pronunciation: Lip trill

Ask your teacher if you are unsure how to produce a sound.

PURPOSE

Connect notes with a light voice and vibrating lips.

KEEP IN MIND

Do not push more air when the vibration stops.

IF DIFFICULT

Use the three-note pattern or a short phrase at a comfortable pitch.

Syllables: Lip trill

Practice patterns

Difficulty describes range, leaps and note count at the same tempo, not vocal ability.

02

Tongue trill

Ask your teacher if you are unsure how to produce a sound.

PURPOSE

Use a tongue trill to explore light phonation and pitch movement.

KEEP IN MIND

Do not press your tongue hard.

IF DIFFICULT

Try three notes or switch to lip trills. Learning to roll your tongue is outside this app.

Syllables: Rolled R
