Improve Fingering

If you have a bad curved hand shape while playing the piano, you should definitely practice op. 849 written by Czerny. 

If you found that your 4th and 5th fingers are weak, you definitely need this etude. 

If you think that your left hand tends to have less strength, you definitely need to master this etude. 

I know this etude op.849 because of no. 5. It has such a lively tune. 

To be able to play this piece well, performer has to hear the right hand tune more than the left hand. Let the left hand roll around non-stop with crotchet sense of beat while keeping the right hand moving around the tune with articulation and music rests accurately.
