Abstract: A liquid discharge method of discharging a liquid from a nozzle of a liquid discharge head by applying a drive pulse to a drive element of the liquid discharge head includes an acquisition step of acquiring a discharge characteristic of the liquid from the liquid discharge head, as a recording condition, and a driving step of applying the drive pulse to the drive element. The recording condition includes any of an angle of a discharge direction of the liquid discharged from the nozzle with respect to a reference direction, a drive frequency of the drive element, and an aspect ratio of distribution of the liquid discharged from the nozzle. In the liquid discharge method, in the driving step, the drive pulse that varies depending on the recording condition acquired in the acquisition step is applied to the drive element.
