Voice resonance: humming on M, N and L
Your voice sounds flat or small, as if it lives only in your throat. Here you hum on M, N and L to find where it resonates, then carry that fullness into a spoken line.
- 1Do the “Reset” (A01): a yawn and a moan. Make sure your throat is relaxed.
- 2Close your mouth and start humming “mmmm”: calm and steady, as if you're purring. Your lips should vibrate slightly (put a finger on them and you'll feel it).
- 3Put your hand on your chest and feel whether it vibrates. If it does, you've switched on your chest resonator.
- 4Now hum “nnnn” (or “ng”, as at the end of “sing”). Put your hand on the bridge of your nose: you should feel vibration there. That's your nasal resonator.
- 5Now “llll”: press the tip of your tongue to the ridge behind your upper teeth and hold the sound. Put your hand on your forehead and look for vibration there. That's the “mask”, your facial resonator.
- 6Switch between “mmmm”, “nnnn” and “llll” and notice where the vibration is strongest.
- 7Finally, hum “mmmm” and, keeping the buzz, say an ordinary line aloud: “Good evening, my name is…”. Your voice should sound as full as the hum.
tip · Your throat is a phone speaker. Your resonators are a concert sound system. The goal is to learn to “switch on the sound system”.
check yourself · Your hand picks up vibration in your chest, nose or forehead. If only your throat buzzes, the sound is “stuck”: relax it with the moan from A01 and send the sound forward.
Why it works
The vocal folds on their own make a small, plain sound. Fullness comes from resonance: the chest, the nose and the bones of the face pick up the vibration and amplify it. When the sound gets stuck in the throat, those amplifiers stay off, and the voice sounds thin however hard you try.
Humming is the easiest way to switch them on, because with your mouth closed the vibration has nowhere to go but into your body. Your hand on your chest, nose or forehead tells you where the sound is. The last line, said straight out of the hum, is the bridge to speech: you keep the same buzz in words, and that buzz is what makes a voice pleasant to listen to.
Common mistakes
- Humming too loud. Loud humming tightens the throat. Keep it calm, as if you're purring.
- Skipping the warm-up. With a tight throat the vibration stays there. Yawn and moan first.
- Judging by sound instead of touch. Your voice sounds different inside your head. Trust what your hand feels.
- Losing the buzz on the words. If the line sounds thinner than the hum, hum again and start speaking right out of it.
Questions
- How can I make my voice sound richer?
- Make it resonate. Humming on M, N and L wakes up your chest, nose and face, and your voice gains depth without extra volume.
- Is humming good for your voice?
- Gentle humming is one of the safest voice exercises: it uses little air and no force. Keep it quiet and comfortable.
- Is this a singing exercise?
- No. Singers hum too, but here the goal is your speaking voice: calls, meetings and presentations. You don't need to hit notes or know your range.
