Suggestions for better "open meter" symbol?

I’m going to be working on a number of vocal pieces which alternate between open meter sections and metered ones.

I’m not crazy about the “X.” Is that standard? Is there another (more elegant) symbol that others have used to indicate open meter?

If X is the standard, I guess I’ll go with that.

I’m used to seeing no symbol. If the open bar is a lot longer, it’s obvious enough. And if it has recitation tones, even more obvious. But if the length is close to the previous meter, I guess you’d need some sign. Maybe just a double barline?


Thanks, yeah I was thinking double barline could be sufficient.
