Yorùbá Tone Sandhi and the Limits of Dò Re Mí
I'm studying Yorùbá on my own, and I've found that the treatment of tone in the resources I'm using isn't as robust as I'd like. Very few go into the details of the rising or falling tones, opting instead to present three level tones (which is not at all how the language works). I'd appreciate any recommendations on resources for drilling Yorùbá tones, particularly tone combinations and the tone sandhi of the language. The following sentence inspired this post:
Ṣé Kóyè fẹ́ sùn?
In the above example, are the last three syllables falling-rising-falling (i.e. high-high-fall-rise-fall)? Do any of them retain their level pitch? And more generally, where can I find out about the true nature of Yorùbá tones (not the do, re, mi stuff) and how they relate to one another in longer utterances? Are there indigenous ways of talking and thinking about tonality that might help learners?
