Beginners can learn this song in one day.
You will play with both hands but the left hand is very easy for the verse because the hand position stays the same. For the chorus, you need to move your hands.
Use the sustain pedal for this song. You can let it depressed all the time at the beginning. With more experience, you will hear that the sound is better when you release and depress the pedal just before you start a new serie of notes.
The A# note at the beginning of the song is the first black key below Middle C.
I suggest fingers position as natural as possible. If you can, try to follow these instructions to start with a good piano fingering.
