A greater variety of tonal patterns is found in the ideophones (expressive words) of Tumbuka; for example Low (yoyoyo 'disintegrating into small pieces'), High (fyá: 'swooping low (of birds)'), High-Low (phúli 'sound of thing bursting'), and Low-High (yií 'sudden disappearance'), etc [REF].
There does not seem to be any consistent, direct correlation between tone in Tumbuka and focus [REF].
