intonation ~ cadence

 * The melodicity vs monotony of a voice


 * mainly a rise and fall of pitch to communicate intention/attitude


 * though also involving many concomitant features such as:
 * tone
 * average frequency


 * pitch-range;
 * min-max frequency*


 * volume
 * amplitude


 * dynamics
 * changes in amplitude


 * rythmicality
 * in/consistancy of isochronic patterns


 * tempo
 * Beats per minute (averaged)

VOCAL RANGE
///min max frequency of a vocal register (most commonly modal) average male: 65-260 ambiguous overlap: 100-260 average female: 100-525

REGISTER
modal fry falsetto whistle

FORMANT
///waveform interference between frequency components in a spectrograph (created by combining multiple resonances) (this is how vowels are constructed) EG.       http://auditoryneuroscience.com/vocalizations-speech/two-formants

RESONANCE
///using different types of resonant vocal chambers to affect both the brightness and timbre head nasal mouth chest

BRIGHTNESS (/CONTRAST)
///brightness ~ spectral centroid

EG.

"nasal" resonance = bright ~ high centroid frequency

"chest" resonance = dark ~ low centroid frequency

PITCH (HUE)
///pitch ~ fundamental frequency

EG.

high pitched ~ high fundamental frequency

low pitched ~ low fundamental frequency

* (brightness/darkness can alter percieved pitch through overtones)

* (volume can also affect percieved pitch [low~low high~high] to some degree)
