I use Mikrokosmos book 1 for elementary sight-reading with students who are too mature for Piano Adventures. I have a small group of students who are all about the same reading level and two of them got to "Pastorale" this week. Both had an incredibly rough time with it. I'm wondering if anyone else thinks Pastorale is a bit out-of-order in terms of the difficulty progression of Mikrokosmos. Key signature is three sharps (it's only the second piece in the book with a key signature other than C major), the left hand has a lot of ties, and it's one of the first 5-6 pieces with independent hand movement... all at the same time! The rest of Mikrokosmos book 1 only has one piece with a non-C key signature and that's only 2 sharps. The later pieces continue to have independent hand movement. I'm already planning on skipping Pastorale with the next student and circling back to it later.
