chopin concerto e moll chopin institute edition
With a little judicious application of this, any edition will qualify.
waste of time
The only fingerings i ever look at with any influence on my playing are Liszt's. His fingerings are from him trying others and finding the best and writing it down, or he uses them to emphasize a point as Ian said. LIke in the Mazeppa, the 24 24 24 24 24 fingering is very important and it doesnt sound right if you use anything else.
Unless you're an experienced pianist who is experienced in the reasoning behind suggested fingerings and why they may or may not be helpful, the fingerings suggested in various editions 'can' be useful much of the time because they may be there to help the player use the correct legato, slur or staccato for example, or to make use of all 10 fingers. Some students ignore suggested fingerings because they find them difficult, perhaps because a weaker 4th finger is used or it just feels plain awkward. It may be that the suggested fingering is not the best for 'you' personally but it's always worth giving it a try because it may be there for the reason I mentioned above. If you always try to miss using a weaker finger, you can lose the opportunity to develop strength in that finger, thereby leaving yourself playing with 8 fingers instead of the full 10! So it's always worth giving a suggested fingering a try before you give up on it completely, particularly if you are an inexperienced player.
