This paper examines the beginnings of intonation phrases at possible topic and sequence junctures in a naturally occurring English telephone conversation. It shows that the two speakers systematically make use of high pre-heads in conjunction with high onsets at these sequential locations to mark turn-constructional units as topic- and/or sequence-initiating. What counts as high pre-head appears to require a positionally sensitive answer: high with respect to the speaker's voice range in turn-initial position but high with respect to prior syllables when the turn-constructional unit is rushed into within a turn. The study further suggests that choice of pre-head height is not dependent on onset height and thus that high initial boundary tones are a resource deployed independently, e.g. in the management of topic and sequence organization in everyday conversation.
