> There's some strong similarities there. In that they both use a descending chromatic line over a minor chord in the harmony, a device that has been used in music for over 300 years. Their differences are great, notably in the structural importance of the figure (it happens in the middle of an ambient passage in Taurus, but it's the opening, passage of Stairway); in the fact that Stairway uses a melodic line on top of the chords, whereas Taurus doesn't; and that Stairway uses it as a structural block for the whole song, and in Taurus, it's only a moment in the middle of a larger section.
