Mea culpa, mea maxima culpa! I should have tried it out on the keyboard before posting; obviously those notes must be played by the right hand.
I haven't played the piece in a long time, but it all comes back to me now. What used to drive me crazy especially are the a's at the end of measures 2 and 4. No matter what I did, I couldn't make them sound like part of the accompaniment instead of part of the melody.
As my teacher said at the time, Schumann's Scenes from Childhood are not for children. (Even though Schirmer packaged them with the Album for the Young.)
