Hi all! I'm pretty much a lurker here but I learn a lot from reading your posts, so when I had a question I knew where to turn...

So a friend has asked me to learn Hallelujah, specifically Linsey Stirling's version, or as close as I can get.  She has the piece in D. One thing I've never been good at is figuring out what positions are best for pieces.  I'm curious what you think she is doing here, or what choices you yourselves would make.  I *think* she is starting in first to play the F# then popping to 3rd so she can easily hit the higher runs and use vibrato with no open strings or 4th finger vibrato, then coming back down to 1st to close out the phrase on the low end...?

What would you guys do?  Alternate between 1st/3rd or pick one and commit?  She may be playing the whole thing in 3rd, is that fairly common for keys like A/D/G that have a lot of otherwise open strings?  I'm always interested in how people interpret pieces for their own ease!

Thanks
