This paper presents the results of a corpus study which examines the impact of frequency of occurrence of accented words on the realisation of pitch accents. In particular, statistical analyses explore this influence on pitch accent range and alignment. The results indicate a significant effect of frequency of occurrence on the relative height of L*H and H*L pitch accents and an also significant but more subtle effect on the alignment of L*H accents.
