  The leading term of the asymptotic of quasinormal modes in the Schwarzschild
background, omega_n = - i n/2, is obtained in two straightforward analytical
ways for arbitrary spins. One of these approaches requires almost no
calculations. As simply we demonstrate that for any odd integer spin, described
by the Teukolsky equation, the first correction to the leading term vanishes.
Then, this correction for half-integer spins is obtained in a slightly more
intricate way. At last, we derive analytically the general expression for the
first correction for all spins, described by the Teukolsky equation.
