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 '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. –  Feb 17 '16 at 00:54

It means quite simply that the voice in question is moving between the staves (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.

In Barbershop style notation, such a line indicates that the melody is moving from one voice part to another. By convention, a voice part does not move from one staff to the other.

In this case, it looks as if one musical line (perhaps on a single-note instrument or voice) moves from the treble clef staff to the base clef staff and then back. As a singer, I would find this confusing.

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

An example of how this is notated.

Gliss

  • Glissando can be applied to other instruments, right? Besides that, gliss is what came to my mind as well. +1 – Shevliaskovic Mar 06 '16 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. –  Mar 06 '16 at 13:27

    Isn't glissando meant to be a wavy line, not a straight line connecting cleft. I believe it's moving voices. – Ayanthi Anandagoda Dec 19 '16 at 03:56
