The article presents an analysis of the typical features of shear Alfvén waves in tokamak plasmas in a frequency domain ranging from the `high' frequencies (ω ≅ vA/2qR0, where vA is the Alfvén speed and qR0 is the tokamak connection length) of thetoroidal gap to the `low' frequencies, comparable with the thermal ion diamagnetic frequency ω*pi and/or the thermal ion transit frequency ωti = vti/qR0 (where vti is the ion thermal speed).
