For an increasing homeomorphism F of the real line such that F-Id is of period 1, the average amount by which every point is translated under the map is given by the translation number. Similarly for an orientation preserving circle homeomorphism f the average angle by which every point on the circle is rotated is given by the rotation number. One can study the parameter space of certain family of circle maps using the translation and rotation numbers. In this talk the structure of the "Arnold tongues" for a certain family of circle maps is discussed.
