苦心
くしん
- middle-high (nakadaka): falls after mora 2
- head-high (atamadaka): falls after mora 1
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).
pain, trouble
Kushin is 苦 (ku, “hard, energetically”) plus 心 (shin, “heart”).
