Now try to minimize looking at the keyboard for every note by just visualizing the keyboard mapping and your finger positions. You might also experiment by playing it on a different octave, just to see how easy it is to do so (just by re-positioning your thumb on a different C note). Now name that tune. Hopefully, you recognized it as Ode to Joy. OK. Congratulations, you've started reading music and playing the piano. And you can brag that already you can locate any natural note on the keyboard.
Obviously, this is just a very simple start to illustrate how quickly a new student of music can find the notes on the keyboard. You'll still need to learn to:
Start with your thumb on a different keyboard key other than C
Play multiple notes at the same time to play a chord.
Play notes of different duration.
And yes, play with your left hand... At the same time !
But the point is, these skills are all about learning to play the piano, not about learning to read the notation. As far as the notation itself is concerned, you still need to learn how to read two more important elements. The first is how to recognize and play sharps and flats (the black keys). And the second is how to read and play notes of different duration. But the WYSIWYP notation for these is visually intuitive and is easier than what you have just learned.
