What musical symbol is this?

Is it a tremolo perhaps? Or anything else on this page?

@Mariah Most likely. Also, I thought I already looked at that page and I didn’t see anything. The only difference that I see is that the lines are going in the opposite direction.

Yeah, I’m thinking they might be drawn in the direction from one note to the next, so since the first note is higher the lines would slope downwards. At least, that’s what I seem to be recalling from a piece I played that had tremolos. But I could be wrong; hopefully someone with more knowledge on the subject will stop by.

Also, I just remembered that the measure is twice as long as what the time signature would allow, which follows the notation on the tremolo wikipedia page.

Oh yeah, that seems like that would only happen if it were a tremolo.

Does it look like a cesura?

In musical notation, caesura denotes a brief, silent pause, during which metrical time is not counted.

It might also be a simile, but both cesura and simile go from upper right to lower left. Simile (scroll down until you see it).

Caesura was my first thought but those are only two lines.

I know, @Mariah. But I know of nothing that slants the way the OP describes it.

@PhiNotPi Are you seeing something like this? If so, it’s a special kind of tremolo. The measure is not twice as long as the time signature allows, but rather you are supposed to alternate between the two notes for the space of one half note.

It’s a tremolo. Basically just trill between the two notes written for a half note.
