This example uses some stretched out voicings in the key of C#m. Make sure that in the third voicing your second finger is not deadening the third string. In essence, we've got a nice ii-V move going on here because in the key of B C#m7 to F#7 would be a ii-V. Notice the nice shimmering quality that is provided by the open strings ringing.
