| A brief melody |
 |
Shows how the vertical ridge associated with residue pitch
moves as the melody proceeds |
| The effect of acoustic frequency |
 |
The pitch fades away as the energy moves up in acoustic frequency |
| The lower limit of melodic pitch |
 |
The pitch disappears as the repetition rate drops from 40 to 20 cps |
| Normal covariation of repetition rate and acoustic frequency |
 |
The normal covariation produces a set of normal notes across the centre
of the domain of melodic pitch |
| Acoustic frequency rising as repetition rate drops |
 |
The pitch goes down and the ridge moves up into the 'rattle pitch' region
in the upper left of the auditory image |
