  In a recent Letter [S. Ganeshan, E. Barnes, and S. Das Sarma, Phys. Rev.
Lett. 111, 130405 (2013)], Ganeshan et al. present a general framework to
classify the resonance structure of Landau-Majorana-Stuckelberg-Zener
interferometry into three basic categories distinguished by whether these
resonances correspond to periodic or nonperiodic quantum evolution. In this
Comment, we show that their identification of the real resonances in the regime
of small drive amplitude is incorrect.
