What you are training
Descending slides start in the easy, light top of the voice and carry that quality downward, which is the opposite of what most untrained singers do. Starting high and sliding down keeps the folds thin and the sound released, so when you arrive in the lower range you bring the head-voice ease with you instead of dragging chest weight up. It is the exercise behind a smooth mixed voice and it is nearly impossible to strain on. This exercise plays a reference slide from a comfortable high note to a comfortable low one and follows your pitch on the way down. Notice the moment the sound thickens; that is where chest voice wants to take over, and the goal is to let it arrive later and more gently each time. Three minutes, and your middle range feels easier.
How to do it
- Start on a comfortable mid note and slide DOWN a fifth on "vv" or "zz", like a sigh with sound in it.
- Down first, not up. The voice is stiffest at the start, and descending slides let the folds lengthen without asking them to stretch.
- Keep it quiet. This is circulation, not singing.
- 6 slides, each starting a half step lower than the last.
Almost every warmup here ascends, which trains singers to reach on a cold voice. Starting downward is standard practice for a reason: descending phonation shortens and thickens the folds, which is the low-effort direction. Pairs with [[warmup-lip-trill-5]] and belongs before it on a genuinely cold morning voice.
After this exercise, the plan: The daily plan uses descending work as the bridge into mixed voice, then adds ascending patterns once the top stays light on the way down.
If singing hurts, stop. Pain, hoarseness, extra effort, loss of range, or repeated throat clearing that lasts more than a day is a reason to see an ENT or laryngologist, or a speech-language pathologist who specializes in voice. It is not a reason to practice harder.
