I bought Lyric Pieces. It's the sheet music to all of Grieg's Lyric Pieces. There have been editions of this before. I had borrowed the Bertha Feiring Tapper edition before, but at c. $80 for one book, I couldn't justify buying it. I was happy when this new edition came out at a reasonable price.
Also, the fingerings here are cleaner in a few places. I have in mind Vogelein, where Tapper had some strange fingerings that may have been mistakes.
