Rightward tone spread on to all following untoned tone bearing up to a syllable bearing lexical tone or, where there is no such syllable, to word boundary.

H becomes D in the environment of a preceding HL

Where a sequence of H and L occupy adjacent moras within the same syllable, the syllable is realised with a surface F tone.

A word tone melody is assigned as a manifestation of word initial prominence. The first metrical syllable of a word receives prominence. One manifestation of this prominence is the assignment of an HL melody.

Each lexical item may optionally receive a lexically assigned HL melody. This melody is assigned to any syllable following that bearing word initial prominence and the HL melody which expresses this prominence. The location of the syllable to receive the lexically assigned HL melody is determined by the lexicon.

Only a sub-category of lexical compounds function as tonal compounds. The first item in a lexical compound must have either (i) no lexically assigned HL melody, or (ii) a lexically assigned HL melody on the syllable immediately following that of the syllable bearing word initial HL. In lexical compounds, the lexically assigned HL melodies of items described in (ii) are unrealised. The H-tone of the word initial HL melody associates with the first mora of the word initial prominent syllable, the L with the second mora. The L then spreads up to the syllable bearing the next HL melody.

Each word has a maximum of a single lexically assigned HL melody. This may be assigned to any syllable other than the first metrical syllable.

Talking Rhythm, Stressing Tone: The Role of Prominence in Anglo-West African Creole Languages by Devonish, Hubert - 2002
document type: book
pages: 82-119
publisher: Arawak Publications
address: Kingston, Jamaica
notes: The book covers the suprasegmental systems in Anglo-West African Creole languages. It seeks to trace the development of these systems resulting from contact between European stress accent languages and West African tonal languages. The work provides provides evidence, by way of an analysis of a range of these languages which indicates that they show a mixed system of stress and tone. The key example was Guyanese Creole, on which is tested the theory of prominence presented in the work. This theory, as presented in the work, seeks to establish prominence as the factor which unites tonal, stress accent and hybrid systems.

Talking in Tones: A Study of Tone in Afro-European Creole Languages by Devonish, Hubert - 1989
document type: book
pages: 72-135
publisher: Karia Press & Caribbean Academic Press
address: London & Bridgetown, Barbados
notes: This book analyses the nature of the tonal prosodic systems which have emerged in languages that developed through contact between West African tone languages and stress accent European languages like English and Portuguese. In the second part, it focusses on certain phonological changes which have taken place in languages such as Guyanese (English-lexicon) Creole. These changes have made such languages simultaneously both more similar to English at the segmental level and more distant from English at the prosodic level.

Some suprasegmental features of Caribbean English by Allsopp, Richard - 1972
document type: conference
organization: Conference on Creole Languages in Educational Development, University of the West Indies, Trinidad & Tobago
pages: 120-133
notes: The paper argues for tonal distinctions involving minimal pairs with word initial stress. Some such words carry relatively high pitch on both syllables, and others low pitch on the first syllable and high pitch on the second.
