Vocal Siren

The siren gets its name from the emergency vehicle sound. You glide continuously, hitting every pitch in your range — not just the scale degrees. This "fills in the gaps" between notes and trains smooth muscle coordination across the full vocal spectrum.

Because you're gliding through every pitch rather than stepping between them, you can't avoid your passaggio — you have to pass through it. Over time, consistent siren practice is the most reliable method for eliminating the audible break and expanding the total range of the voice.

1. 01Start on any low comfortable pitch. Use "ng" (as in "sing") or "wee".
2. 02Slowly glide upward in one smooth, continuous motion through your entire range.
3. 03Don't stop at individual notes — this is not a scale. Every pitch is visited.
4. 04At the top of your range, reverse direction without stopping.
5. 05Glide back down through every pitch to where you started.
6. 06One full siren (up and down) = one repetition. Do 5–8 per session.
7. 07Gradually extend: try to reach higher with each siren.

• "NG" siren: the nasal consonant encourages forward resonance and discourages throat tension.
• "WEE" siren: the "w" onset relaxes the larynx; the "ee" vowel encourages head voice.
• Think of it like a race car shifting gears — continuous, not stepping.
• The siren should always be soft and effortless, especially at the top.

• Stopping or slowing dramatically at the passaggio — push through smoothly.
• Using too much volume — sirens should be gentle, not powerful.
• Avoiding the top of the range — that's where the growth happens.

• 01Partial siren: just through the passaggio — up and over the break 10 times.
• 02Fast siren: quick glides up and down, like a whip. Trains agility.
• 03Siren on vowels: "ah", "ee", "oh" each produce slightly different resonance challenges.
