Abstract
We give an elementary introduction to the theory of quasi-periodic oscillations based on their basic property of frequency incommensurability. First, we provide their brief mathematical description, examples from physics, and the visualization and measuring methods. We also propose a new simple technique for evaluating their degree of non-periodicity. The issues outlined in this article will be useful for instructors and physics undergraduates dealing with the modern theory of oscillations.
