So simple – but effective. This is useful for when singers are sustaining a pitch and it’s hanging just a little flat.
Upper arms against the body
Palms down – as if palms and forearms were resting on a counter top
Sing the pitch and sustain it
If the pitch starts low, or if after a moment or two it begins to droop, turn the palms over.
That’s it. You should hear the pitch perk right up again.
