agreed with fon.  when you are able to repeat a dynamic section (which often repeats the exact notes) -you will feel that that section was really worth learning as it bumped you forward twice.  you don't want monotony with schumann.  maybe learning a little poetry at the same time and singing it with your music will remind you of the rhythms/melody/ and sometimes even notes!  (if the word matches the note). 

i like to use this sort of 'singing' technique with brahms, too.  it helps you also understand the piece.  errinerung means 'memory' right?  there's a poem somewhere here on the internet of the poem schumann was deriving this piece from.  i think from 'knaben wunderhorn.'  it's in german here:  https://gutenberg.spiegel.de/arnim/wundhorn/wundhorn.htm

something about the memory of a loved one and get into the feeling of what is actually the present.  is someone present when they are here or also when they are gone?  he remembers all the pleasant times as here and now and yet also past and present - making the loved one a fullness of reality.
