Effects of pressure on the electronic structure, electron-phonon interaction,and superconductivity of the high entropy alloy(TaNb)$_{0.67}$(HfZrTi)$_{0.33}$ are studied in the pressure range 0 - 100 GPa.The electronic structure is calculated using the Korringa-Kohn-Rostoker methodwith the coherent potential approximation. Effects of pressure on the latticedynamics are simulated using the Debye-Gr\"{u}neisen model and theGr\"{u}neisen parameter at ambient conditions. In addition, the Debyetemperature and Sommerfeld electronic heat capacity coefficient wereexperimentally determined. The electron-phonon coupling parameter $\lambda$ iscalculated using the McMillan-Hopfield parameters and computed within the rigidmuffin tin approximation. We find, that the system undergoes the Lifshitztransition, as one of the bands crosses the Fermi level at elevated pressures.The electron-phonon coupling parameter $\lambda$ decreases above 10 GPa. Thecalculated superconducting $T_c$ increases up to 40 - 50 GPa and, later, isstabilized at the larger value than for the ambient conditions, in agreementwith the experimental findings. Our results show that the experimentallyobserved evolution of $T_c$ with pressure in (TaNb)$_{0.67}$(HfZrTi)$_{0.33}$can be well explained by the classical electron-phonon mechanism.
