what is the trick behind using two different hands to play several different notes with different fingers

I'm very much a beginner at trying to play the piano, so this may be wrong, but afaik there is no trick. But there are things you can do to shall we say "ease the pain":

• I found this technique very helpful
• I installed EasyABC on my laptop, then typed in the scores of the simple tunes I want to learn. Then, using the % (comment) sign in EasyABC, I can disable one hand in the score, and have a simple means of playing back to me only the hand I'm struggling with and for which I need a known good sample. Master one tiny bit at a time, even maybe just one measure, one hand at a time, then bolt it all back together a bit at a time. EasyABC also lets one change the tempo very easily. As far as this beginner (aged 67 I might add....) is concerned, there's no trick, just plug away at it. (Starting really simple of course: I have Thompson's old material from the 1930s.)

EDIT:

Aaron asked-

Please add a description of the video in case it is sometime taken down and the link becomes meaningless.

The creator of the video (YT handle "Piano Superhuman") provides a short piece to play, but suggests the technique for any piece one wants to learn. These are the steps:

1. Get good at each hand's part separately, a small section at a time
2. Get good at the rhythm, just tapping it on your legs with both hands
3. Play the rhythm using only your thumbs, eg just say a C on each hand
4. Then play the rhythm with say the left hand, and the notes with the right
5. Swap: notes on the left, rhythm on the right
6. Play both
7. Do that for longer and longer chunks

This is the music he provides, but as I said I'm using this method with Thompson's beginner pieces, Music Land, Patterns and so on.

CAVEAT: This is obviously nowhere near touching on professional: I am right at the bottom of the piano-playing spectrum, probably not yet even on the spectrum ;)
