__Starting pitch: __ The starting point for the first syllable in your sequence.

__Upper bound: __ The upper limit on your y axis.

__Lower bound: __ The lower limit on your y axis.

__Order: __ Specify the number of derivative in the system.

__Tones: __Tone specification for each syllable in your sequence.

__Duration: __Duration specification for each syllable in your sequence.

__Strength: __Strength specification for each syllable in your sequence.

Specifications for the target height and slope of tone categories in Hz. Dynamic targets such as R or F have a positive or negative slope respectively. Static targets such as H or L have a slope of 0.

Duration(s) and strength specification for each categories.

__Basic assumption: __Production of tone and intonation is a process of successively approaching
syllabic pitch targets at varying pitch ranges with different levels of strength.

__Pitch targets: __specified by: y = b + a * x, where b is height and a is slope.

__Duration: __Specifies duration of each syllable, which is the temporal domain of a target.

__Strength: __Determines the amount of strength used to approach a target. Greater strength
leads to faster target approximation.
