Neutral

Description and Sound

Neutral with air

Sustained single notes in Neutral with air

Glissando in Neutral with air

This video is a male singing a glissando from low pitch to high pitch returning to low pitch again on the vowel AH (as in ‘far’) in Neutral with air. Notice that the waveform stays the same through the Neutral with air pitches – it just gets narrower as the pitch increases.
