Direct observational evidence of wave and oscillatory activity of the solar corona is abundant in all observational bands and includes recent discoveries of propagating compressible waves in polar plumes and near loop footpoints, flare-generated transverse oscillations of loops, and longitudinal and sausage standing oscillations within loops. These phenomena are successfully interpreted in terms of magnetohydrodynamic (MHD) waves. This observational breakthrough gave rise to the rapid development of a new method for the remote diagnostics of the coronal plasma, MHD coronal seismology, allowing for estimation of the absolute value of the magnetic field in coronal loops, Alfven speeds, transport coefficients, fine structuring, heating function and other important coronal parameters. EIS and XRT instruments are excellent tools for the further development of coronal wave studies and especially flare generated oscillations and waves. We present the recent findings, theoretical estimations of the observability of different MHD modes with Solar-B instruments, theory-based observational and data analysis strategies and some ideas about the utilisation of the results for coronal seismology. The expected results are of particular interest for the revealing of coronal heating mechanisms.
