The next micro study requires the excellent use of smart guide fingers to work. If you have played through Etude No. 4 you should have no trouble with the first two bars, other than having to iterate over them to get used to the unusual chord shapes.

The last two bars are here, but really should not need any work, just the opening idea again. Use this point as a mental break, a sign post moment, to collect yourself before diving into the next section of harmonic ideas.

A short pause here and consolidate advice for what you have learnt so far.
It holds true for each segment you complete.
Make sure you do not allow any errors to creep in at this stage, your body will retain these and they will need ironing out at a later stage. So take it slowly and perfectly – if you can! (You are 1/2 of the way through!)
