This paper poses two interrelated questions. (i) What aspects of pitch movement and the segmental stream are aligned? (ii) What does it mean for these aspects to be aligned? Our basic claim is that these aspects are unlikely to be found at the acoustic surface level, and that alignment itself involves an abstract relationship rather than, for example, the simple coincidence of certain discrete pitch events (e.g. peaks) with discrete segmental events (e.g., syllable boundaries.) This abstract relationship consists of a mathematical mapping between intonational and segmental trajectories that is invariant within a given phonological category and "speech state." We present a conceptual framework that makes this claim more precise, and illustrate the framework by discussing in detail a specific model, the Linear Alignment Model (A Model of Fundamental Frequency Contour Alignment", in A. Botinis, Ed., Intonation: Analysis, Modeling and Technology.)
