For arbitrary scalar masses $M \\mu$ and black hole spins $a/M$, we numerically determine the quasinormal frequencies for various orbital $\\ell$, azimuthal $m$, and overtone $n$ numbers. In particular, we derive an analytic expression for frequencies of the zero-damping modes near the extremal limit $a/M \\rightarrow 1$. For $\\ell=m=1$, we reveal that the fundamental mode becomes a damped mode (rather than a zero-damping mode) if the scalar field is sufficiently heavy.
