Using the Nambu--Jona-Lasinio (NJL) model we study responses of the pion and
kaon masses to changes in the chemical potential, $dm/d\mu$, at zero and finite
chemical potential. We find that the behavior of $dm/d\mu$ for the pion is
quite different from that for the kaon. Our results can give a clue for future
studies of $dm/d\mu$ on the lattice.
