The linear theory of flute modes in a finite-..beta.., inhomogeneous, magnetized plasma is developed. The collisionless Vlasov equation is used in a slab geometry, including the effects of a constant gravity field. The magnetic drift mode and the g x B mode are examined, and their stability properties are described. These two ''modes'' are shown to be different limits of the general finite-..beta.. interchange mode. The wave-particle resonances, between the flute modes and the particles that delB drift perpendicular to the unperturbed magnetic field, are included in a self-consistent manner.
