Double stop terms I've never heard of...

Okay, I just came across some double stop terms I have never heard of and I'm wondering if someone here knows them and can explain. The PDF paper I found them on does not explain them, but it appears they somehow have to do with how far the finger stretches, or something along those lines. The terms are:

TINY
UPTENT
DOWNTENT
TWO-SPACER
BAR
STRETCHY

(And that is exactly how they were written.)

Hi and thank you for your post. Please, could you please answer me the following questions:

1. Is that PDF from our archives? If so, that's the title of the piece?

2. For what is instrument is the piece?

I look forward to hearing from you.

Thank you again.

Sincerely,

Okay, I figured out what those terms were meant for last night. I had come across them after doing a Google search on "violin double stops". Apparently one of the links lead me to some PDF files that were giving a pedagogy for learning double stops on a mandolin. I was thrown off by the fact that nowhere on the page did it mention the word "mandolin", and that the tuning under discussion was GDAE. After some more searching and getting into the context of the text, it then dawned on me what I was reading.

Thanks.

You are very welcome, that makes sense: I never heard about those terms on the violin or other classical string instruments (cello or viola), so I was wondering where you found them!

Thank you.

Best,
