Watch the Towards the Floor online guitar lesson by Brad Carlton from Chord Studies: Evolving Progressions Vol. 1
Up next we've got a I - iii - vi - V in E Major. When facilitating the change between G♯m and C♯m, all you have to do is move each finger one string towards the floor and drop your second finger. You then shift the chord shape down one position, and play your major barre chord shape for the V chord, B major.
