Maybe the majority of the world’s languages are tonal. but it seems except for chinese, most of these tonal languages have only comparative small number of speakers. so the total number of native tonal speakers is only 1.5 billion, out of this 1.3 billion would be speakers of chinese.
So roughly 80% of the world’s 7.8 billion might struggle with a tonal language.
