Repeated notes on black keys and white keys

[pianoplayjl]

Today I tried out playing repeated notes (to the best of my ability) on black keys and white keys. It wielded 1 result. Why is it that playing repeated notes on black keys are harder than playing the same thing on a white key?

I can only offer one explanation for myself. The black key is smaller than a white key and so theoretically you would have a higher chance of missing a note. A black key is barely larger than my 3rd finger and only just as wide. Are there any other possible explanations?

You probably just solved your own problem!  You need to be accurate to repeat white keys, but you have to be VERY accurate to play repeated black keys... more so if you are playing fast repeated (check out Alborada del Gracioso by Ravel)

I think it may also have to do with physics. The keys are pretty much levers and if you push a lever at a point closer to the fulcrum, then you don't have to push the lever as far, but you have to apply more force.

As for accuracy, I feel like accuracy takes care of itself in repeated notes. The issue is getting the individual notes to actually sound.

This was my thoughts.. black keys should have a marginally greater resistance than white keys..

In saying that, I don't find it harder on black keys so perhaps its just about having a more refined movement..

I find that usually happens when I attempt repeated notes on black keys. I usually miss the black note the first time. Also my hand has to be bent at a more awkward angle as opposed to playing white keys.
My technique has to be very wrong then. As soon as I play the next note it often does not sound. Porbably because I was being too hasty.

I know what you mean by tilting your hand and facing the key from an angle. One loses accuracy play straight forward, so having your finger approach the key from an angle is fine. However, you do NOT want to tilt your hand. This creates a more sideways motion rather than the down motion required to play the key. Although you have your hand at an angle, try not to tilt your palm toward you. Elevating your hand slightly helps.
