快い
こころよい
- middle-high (nakadaka): falls after mora 4
How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).
pleasant, agreeable
Kokoroyoi is 心 (kokoro, “heart”) plus 良い (yoi, “good”).
