Warm up
Two minutes before you sing. A straw, a lip buzz, or a hum wakes the voice without grabbing. The mouth stays partly closed, so a little air pushes back and you do not have to shove. Teachers shorten that idea to SOVT. Do this after standing and breathing, and before shaping a vowel.

Nothing on this page uses the pitch check yet. You are waking the folds, not testing solfege. Turn the drone on in the practice bar if you want a pitch to match — optional for the straw.
Keep volume quiet. If the straw bubbles loudly or the throat scratches, you are pushing air, not phonating easily. Softer, or shorten the straw.
Two or three minutes here, then shape the vowel. Come back to the straw any day the voice feels dry or tight.
What the letters mean
SOVT is short for “the mouth is partly closed.” A straw, a lip buzz, or a hum with the lips together. Air has a smaller doorway, so a little of it pushes back. The voice does not have to shove. The sound stays quieter than singing with the mouth open. That quiet is the point.
Teachers say SOVT so students remember: you are not singing with a wide open mouth yet.
The partial closure can be a straw, buzzing lips, or a hum — the physics is similar enough for warm-up.
Back pressure at the folds often lets them meet more gently. That is why the warm-up feels easier than yelling.
It is not magic and not a cure. It is a daily reset before you ask the voice to move through a scale.
Through the straw
These exercises use only what you already did on Stand and breathe. A paper, metal, or corn straw is fine. A paper cup with a small hole in the bottom works too: lips on the rim, sound into the cup.
Lips seal around the straw. Air goes in through the nose, out through the straw while you buzz. Pinch your nose once while humming: if the sound dies, air was leaking out the nose instead of the straw.
Stay in a comfortable speaking range. Do re mi, leaps, and songs wait until later pages. This warm-up is two or three minutes of easy phonation, not a workout.
What to do through the straw
Voice teachers group straw work into a few jobs. Names vary; the motions are what matter. Do them in this order the first week: steady hum, then small slides, then one optional siren, then open the mouth.
- Steady hum (one pitch). After a low belly breath, buzz one comfortable note through the straw — “mmm” with the lips sealed on the plastic. Hold four to eight seconds. The pitch should feel like speech on a single note. If the drone is on in the practice bar, match that do; if not, pick any easy hum. Repeat two or three times. This is not a song and not a scale — one pitch, steady air.
- Slides / glides (small pitch change). Keep the same buzz, but let the pitch glide slowly upward a short distance — a few notes, not an octave — then glide back down to where you started, still on one breath if you can. Think of a slow “siren in first gear,” not do–re–mi steps. The tone stays connected; you are not starting a new hum at each pitch. VoiceScienceWorks and many choirs call these glides; the word slide means the same thing here. Do three round trips on a hum that still feels easy. Stop before the throat tightens or the straw noise turns to a hiss.
- Sirens (high ↔ low, one connected line). A siren is one long glide from a low comfortable pitch up toward your easy top, then back down — high and low on the same continuous buzz, like a fire-engine sound but quiet and inside the straw. Range is personal: for some people that is a fifth, for others an octave. Never chase the highest note on day one. If the voice cracks or the straw sputters, you went too high or too fast; shorten the siren and try again. One or two sirens end the straw part of the warm-up for most beginners (same idea as the siren on Chest, mix, head, only softer and semi-occluded).
- Transfer off the straw. Take the straw out, keep the same pitch on a closed-mouth hum, then open to “doh” without changing pitch — the balanced onset from Stand and breathe. That last step proves the warm-up carried into open singing.
First-week checklist (same jobs, numbered)
- Close your lips around the straw and take a low, quiet breath.
- Steady hum: one comfortable note four to eight seconds. Match the drone if it is on.
- Pinch your nose once. If the hum dies, fix the seal — air should not escape through the nose.
- Slides: three small glides up a little and back down, still buzzing through the straw.
- Optional siren: one quiet high ↔ low glide in your easy range, or skip until slides feel smooth.
- Straw out → hum → open to “doh” on the same pitch.
When that checklist is boring, you can add more slides or a second siren — still not scales through the straw. Titze’s longer straw sessions (including singing through a straw) are for later; see the link in the tip on this page.
Vocal fry
Vocal fry is the creak at the bottom of the voice. Say “uh” and let it run out of air until it rattles, like a door hinge or the last scrap of a sleepy sentence. Some teachers send a little of that creak through a straw. It is easy to squeeze your throat while you hunt for it, so this warm-up does not use it.
Fry is the lowest creak of the folds. Some methods use a little fry through a straw to find a relaxed close.
It is also the easiest place to squeeze the neck while hunting for the sound.
This book skips fry in the warm-up on purpose. Hum and slide first; add fry only if a teacher asks for it.
If you already use fry in speech, notice whether the throat feels free or pinned after.
No straw
Same two jobs: one comfortable hum, then a slow slide up and back down. Soft. If it scratches, you are pushing. Ease off.
Travel, school, and shared spaces often mean no straw. The shapes in the table are the portable version.
Pick one shape for a week so your body learns it. Switching every day hides which one actually helps you.
Volume stays low. SOVT is not “sing loud through a buzz.” Quiet is what keeps the folds from slamming.
After any shape, open to “doh” on the same pitch. That transition is the proof the warm-up worked.
| Shape | How |
|---|---|
| Mmm | Lips together. Hum. Then slide. |
| Nnn | Tongue tip behind the upper teeth. Hum. Then slide. |
| Ng | The end of the word “sing.” The sound sits in the nose. Then slide. |
| Vvv | Top teeth on the lower lip, as in “love.” Buzz. Then slide. |
| Zzz | The buzz in “buzz.” Keep it at the teeth, not squeezed in the throat. |
| Lip buzz | Loose lips, “brrrr,” like a horse. Fingers on the cheeks help if the lips clamp shut. |
| Tongue roll | A rolled “rrrr.” If your tongue will not roll, use the lip buzz. |
When to come back
Use the straw or the hum any day the voice feels off, before you sing.
Morning, before a rehearsal, after a long meeting — any time the voice feels thick or unreliable.
Do not wait until you are already shouting in a song. SOVT is prevention, not a rescue after damage.
If the table says “tight,” softer always comes before louder. Louder SOVT is not better SOVT.
After illness, start here for several days before full scales. The folds need easy cycles first.
| If it feels like… | Do this |
|---|---|
| Airy, almost a whisper | Hum through the straw. The closed mouth helps the sound come together. |
| Tight in the throat | Softer. Let the air do it. The straw pushes back so you can stop shoving. |
| The note cracks as you go up | The slow slide, quieter. Stop where it cracks and slide only that far. |
| Tired | Two minutes of hum, then stop. Do not “sing through it.” |
How this fits the rest of the guide
The sidebar order is deliberate: stand, warm, vowel, hold, then pitch and time on the hub.
Skipping straight to Hot cross buns teaches the tune with a voice that is not awake yet.
Come back to this page between hard songs or belt drills. Two minutes resets the default onset.
Eastern riyaz on the Singing room has its own alankar path; this warm-up pairs with Western movable do.
The sidebar order is deliberate: stand, warm, vowel, hold, then pitch and time on the hub.
- Stand and breathe.
- Warm up (this page).
- Shape the vowel.
- Hold one note.
- Pitch, time, words — do re mi, then Hot cross buns.
Next
Shape the vowel → five vowels on the note you just warmed up. Come back to the straw any day the voice feels dry, before you sing.
Press Play once and listen before you sing. Your turn is for testing, not for guessing.
The check names the pitch you actually sang — adjust until it matches the lit syllable in tune.
If anything pinches, stop and reset on SOVT or a lower do in the practice bar.
Short daily reps here beat one long session on the weekend.
When this section feels easy, move on in the sidebar or raise BPM slightly on the lab page.
