Analytical treatment of the excitation of transverse magnetic tube waves in stellar convection zones is presented. The waves are produced by the interaction between thin and vertically oriented magnetic flux tubes embedded in stellar convection zones and the external turbulent motions. A general theory describing this interaction is developed and used to compute the wave energy spectra and fluxes for the Sun.
