Technique · octave leap
The last bar of “Signore, ascolta”
The final phrase of Liù’s aria in Puccini’s Turandot ends with an octave leap, from A3 to A4, followed by a second up to B4. Solve the octave and the second solves itself.
The strategy
The mouth prepares for the low note as if it were going to sing the high one straight away, and both are sung in that position. You don’t reach for the high note by lifting your face: every note stays in the same place, the vomer, with no more effort than necessary. The strategy works for every octave.
The execution
For the A3, the jaw protrudes forward and diagonally, and the lower lip drops to show the lower teeth. Once the note is held, the muscles joining the lower lip to the fold of the jaw move a little further forward. It is a tiny movement, with the intention of a trombone slide, and with it you sing the A4.
For the B4, the central part of the upper lip rises. The lip corners stay close and the mouth takes an oval shape. The harmonics accompany the fundamental and the high note comes out bright and intense.
The text: “Ah, pietà”
On the “p” of “pie-” the mouth position doesn’t move: just hint at bringing the central part of the lips together, without opening the corners into a smile. For the “e”, think “a”, because “e” is a closed vowel and tightens the sound on a high note. If the “t” of “tà” makes it harder, think of it as a “k” without changing the mouth. The audience will hear “Ah, pietà” perfectly.
What matters is that the sound is produced in tune and without technical difficulty for the face.
To practise: first sing the whole phrase on the vowel “a” until the jaw drop comes easily.
