The technique · 1 of 5

Find where you grip

Sing a line from a song that feels like hard work, in front of a mirror, with a hand resting lightly on the front of your neck. Watch for the jaw jutting forward, the chin lifting, or the neck tightening under your hand. Note the first one you see.

Sing the melody of that line on a lip trill, with no words. Keep the trill even: if it stops, give it a little more air; if it sputters, give it less. Most people find the line much easier on a trill.

Go phrase by phrase: one pass on the trill, one pass on the words. On the sung pass, aim for the same amount of effort the trill needed and no more.

Go back to what you saw in the mirror. If it was the jaw, sing the line with the jaw hanging loose and let the words be slightly less crisp. If it was the chin, keep it level as the line climbs. Change one thing at a time.

Speak a sentence. If your speaking voice feels the same as before you started, the session did its job. If it feels rough or tired, keep tomorrow's practice short and stick to trills and hums.

Read at your pace. Singing is not required.

Why this exercise · 1 of 12

The idea behind it.

Strain is the feeling of working hard in the wrong place. The jaw clamps, the tongue pulls back, the neck muscles stand out, or the breath shoves at a note instead of feeding it.

Most singers who strain do not know which of these they are doing, only that singing feels like effort and gets harder as a song goes on. Some strain is a habit you can train away.

Strain that comes with pain, or a voice that stays hoarse for more than a day after singing, is a reason to see a doctor or an ENT rather than to practise harder.

Your voice is made in a small space, and the muscles around it are big. The jaw, the tongue and the muscles of the neck can all clamp around the larynx when you try hard, and none of them make a note higher, louder or more in tune.

They make the same note cost more, so you tire sooner and your range seems to shrink as the song goes on.

Strain also comes from air. Pushing more breath at a note that is not working is the most natural reaction there is, and it makes things worse: the folds have to resist the extra pressure, and the throat tightens to help them. A steady, moderate airflow does more than a forceful one.

The quickest way to feel the difference is an exercise that will not work under strain. A lip trill stops if the airflow is too weak and goes ragged if it is too strong, and it is hard to clamp your jaw while your lips are buzzing.

A few minutes of trills gives you a reference for easy singing that you can hold your songs against.

The standard fix for strain is "relax", which nobody can do on command in the middle of a hard note. Strain is specific: it lives in a particular muscle doing a job it is not needed for.

Finding which one, and using an exercise that will not work while it grips, turns relaxing into something you can practise.

The free pitch test measures how cleanly you land and hold notes at a comfortable effort. Take it on a day when singing feels easy, so you have a baseline that was not sung under strain.

Every Vocal School session opens with a trill or a hum before anything demanding, and the plan backs off when you report strain. Free tier: one full session a day.

What did you notice?

Is the line easy on a lip trill and hard on the words? Then the strain is coming from the words: the jaw, the tongue or the vowels. If it is hard even on the trill, the line sits at the edge of your current range or you are pushing air at it, and singing it quieter or in a lower key is the better practice for now.
