How to Strengthen Fingers' Power and Speed

[ratihmaharani]

Hello, i need your advices about strengthen the fingers power.

What kind of exersice that i need to do?

and when i play piano in front of my teacher, the emphasis of my finger is not the same between 1st, 2nd, 3rd, 4th, and 5th finger  . my teacher told me that i should play with my feeling and feel all the keys i press. but i get no differences and i can't feel them.
well, i play with a digital piano at home but at my course lesson i play with an upright piano. the keys are strongly different. maybe that's why i can't prove my power?

What should i do?
Any advice would really help. Thank you so much

I think you should explain this challenge to your teacher. Digital pianos and acoustic pianos keys have different weights and action so that is pretty natural. I don't know what your teacher means by feel all the keys you press nut you may want to consider the shape your fingers make. The more curved your fingers are the more you can compensate for loudness. The challenge is learning how to coordinate the fingers and use the skeletal power of the fingers to control loudness. Putting a sheet of paper in front of you and asking you to play through the exercise will not make your fingers "stronger" or pumped up with muscle. Its more teaching the fingers a new skill and using them in a certain way to produce the sound you want. A simple exercise you can do anywhere is to learn to keep all the muscles of the hand relax, finger curved and tapping from the third joint, and learn to do fast taps on the fallboard of the piano or desk or anywhere. If you teach your finger muscles to move quickly they can make very loud sounds with fingers alone.

mcdiddy1 nailed it.  It's more about mental concentration and being aware of your movements than anything.  I only got to practice once a week with my professor at school, so that was the only time I got to use a real piano to play (aside from a few hours during the rest of the week when I could get to a real piano in a practice room at school).  Every other time (including now, for the past 5 months) I have only had a digital piano to work with, since the upright piano in our house is horribly out of tune.

I have to approach the digital piano with the mindset of playing on a real piano - even if something sounds great on the digital, it still needs twice as much work and concentration to make sure it will sound good on a real piano.  Nothing compares with playing on the real thing, but if you're focused on your actions enough, it will make a difference.
