If you play mandolin decent enough that you can play some Bach you'll love this. I got the other one too, the Cello suites for mandolin by the same publisher. It's what most of us would want, no need for things that were left out like dynamic marks, etc, but this is excellent. I first had to bust my chops over the Allegro from Sonata III, but it saved me A LOT of time having to transcribe it.I have only ONE issue, and it's something almost all these publications leave out, and that's THE BINDING!! These books are for music study/practice and the paperback perfect-style binding is annoying and impractical. Just take these to Staples or some place and have the books spiral (coil) bound. I guess you could get the binding cut and have them punched for loose-leaf binders but the spiral binding is fine. Music books that need to be folded over or sit flat on a music stand should not be perfect-bound. I still don't know why some publishers will not do it.Transcribing some of these pieces and using them for my practice AND students (for over 30yrs) I now get to struggle through the desire toward perfection with the mandolin. I think it's more practical on this instrument anyway because it's tuned in fifths and the mandolin is basically a fretted violin that you can pick. I'm being reminded though just how tough some of these are to get clean, and up to speed. I have said to colleagues and students alike, that there are reasons why "Bach" is a four-letter word!Awesome collection though. Just get these if you want to play the Sonatas but I think you'll be relieved once you have the binding done. Go check out the one for the Cello suites too. Same author and same publisher. The two together make a great Bach mandolin library.
