The tonal system of Kusaal has three tones, high (H) and mid (M), and low (L) (which actually is phonetically a falling tone) as well as a down-stepped high tone (!H), symbolized by acute accent (á), middle accent (ā), grave accent (à), and for the down-stepped high tone a small elevated exclamation mark before acute accent (ꜝá).
High bã́ŋ H ‘bangle’
Mid bã̄ŋ M ‘crocodile’
Low õ̀ bã̀ŋ L ‘he knows’
High-Down-stepped kpã́'ʋ́ŋ H-ꜝH ‘guinea fowl’
Downdrift: The pitch is phonetically lowered at every transition from L to H. Pitch lowering can progress to a point that a H tone relatively late in the utterance has a lower pitch than an earlier L tone.
Stress is on the penultimate syllable.
