  Maggiore observed that, in the high-damping regime, the quasi-normal modes
spectrum for the Schwarzschild black hole resembles that of a quantum harmonic
oscillator. Motivated by this observation, we describe a black hole as a
statistical ensemble of N quantum harmonic oscillators. By working in the
canonical ensemble, we show that, in the large-mass black hole limit, the
leading contribution to the Gibbs entropy is the Bekenstein-Hawking term, while
the subleading one is a logarithmic correction, in agreement with several
results in the literature. We also find that the number of oscillators scales
holographically with the area of the event horizon.
