Fingering - There are many "tricks"

However, the hands can learn almost anything!

Yes, there are many tricks to fingering pieces. Only someone who ACTUALLY LOOKS AT YOUR HANDS and their pluses and minuses (all hands have these, there is no Perfect Hand) can truly guide you to do what is best for your hands and fingers.

As I said above, however, your hands can learn almost anything with enough repetition.

Of course, you'd like to keep this repetition to a minimum. That's the role of the personal teacher.

Now, about those " inked in" finger numbers in your music,...The person doing the inking does NOT know what your hand is like. They can't. I'd say that 80% or more of the "inked in" finger numbers are better for you than anything else, but only that amount. Folks usually try to follow these things cause they a printed in ink.

Remember that people have become generally bigger since the days of the early pianos.
