Good
5/12/2016 1:41:43 PMI purchased this sheet primary for transfering it to my primary instrument cello so I cant really review the difficulty of it. I did find it to be a good arrangement since it all sounded very well. It isnt much more to ask from that. I dont quite understand "Accuracy" but I assume its how accurate the sheet is compared to the original. I havent heard Korobeiniki so much so this is not a professional verdict but I did find the sheet to be of good accuracy compared to my "picture" of Korobeiniki.
