What is the meaning of the straight lines between notes in opposite staves, as shown in the picture? I keep seeing it, but Google and Wikipedia are not helping me.

I just have to ask, where did this music come from? I keep seeing questions like this with such terrible formatting. – MattPutnam Feb 16 at 23:48
At a guess, this is from the Ricercar a 6 from the Musical Offering, @MattPutnam. That is why the "surplus" of rests. To be fair, this would be a very difficult piece to format on a Grand Staff. – Patrx2 Feb 17 at 0:54

It means quite simply that the voice in question is moving between the clefs (and usually between the hands as well). In this case, the voice starting with G above middle C falls an octave to be continued in the left hand until it returns to G below middle C, then rises back up an octave to be played in the right hand.

Edit: Here is the original score of this passage (m.10ff of the Ricercar a 6 from the Musical Offering). Looking at the range of the individual voices, you can well imagine the number of times voices will cross between staves when this is transcribed to a Grand Staff.

If it is for piano then it could be consider to be a Glissandi or Glissando. What guitar players know as a slide.

Example of how this is notated.

Glissando can be applied to other instruments, right? Besides that, gliss is what came to my mind as well. +1 – Shevliaskovic Mar 6 at 13:18
It could be a glissando (which is normally specified with gliss. over the line), but in this case it isn't; it's voice crossings. I've added the original score to my answer so you can see how the voices were originally notated. – Patrx2 Mar 6 at 13:27
