In the ToDI transcription system, an intonation contour is a melodic pattern which occurs in an Intonational Phrase. Each contour consists of a number of tones, H(igh) and L(ow). The notation T is used to refer to either H or L. These tones occur in two locations:
Intonational Phrases are demarcated by %. Not every edge will have a tone. Tones occurring at IP edges are notated %T (initial boundary tone) or T% (final boundary tone). Every accented syllable is marked by a tone or a cluster of tones, called a 'pitch accent'. The first tone of a pitch accent is notated T*. A T* may be followed by further tones to describe the movement from the accented syllable onward.
Here is an example:
All the symbols will be explained in the text. By way of quick reference guide, a list of each element is given, as well as a list of all pitch accents, with approximate indications when they are used.
|H||L||upward/downward movement after L*/H*|
|H%||L%||rising/low ending of IP|
|%H||%L||high/low beginning of IP|
|%HL||Initial falling pitch not marking accent|
|%||half-completed fall/rise at end of IP|
|H*L||High fall from accented syllable|
|!H*L||Low fall from accented syllable, also called 'downstepped fall'|
|H*||High level from accented syllable|
|!H*||Lowered level from accented syllable, also 'downstepped level'|
|H*LH||Pre-final steep fall followed by a gradual rise towards the next accented Syllable, also 'pre-nuclear fall-rise'|
|L*!HL||Low rise fall from accented syllable, also 'downstepped delayed peak'|
|L*H||Rise from low from accented syllable|
The melodic shape of the contour is defined by the consecutive contour shapes defined by the boundary tones and the pitch accents.
