I am a learner of Piano. I have seen many tutorials in youtube, in which the chords are played using left hand and melody using right hand. I come from India. I have heard so many songs that are played using this pattern on a keyboad and it sounds very nice to my ears. I recently enrolled in a piano course in Udemy, but the tutor uses right hand for chords. So, I am really confused at this stage. Is it wrong to play chords using left hand?
Not at all. There is no "wrong" way to play the piano, and different compositions will require different feats of dexterity. Most of the popular music I encounter is "left-hand rhythm dominant," where the left hand creates the chord structure in the lower octaves and the right hand fills the upper octaves with melody. However, exceptions are many throughout the history of music. Pieces which require that the left and right hand both play chords at varying times no doubt exist.
Practice both. When you reach the limits of self-taught dexterity, seek out a teacher who can lay hands on yours. I don't know why this helps but it does. Listen to as much piano music as you can find to train your ear, and play along with it to train your hands.
Eventually you should be learning both ways i.e to learn to play the chords with your left hand and notes with the right hand, vice-versa and sometimes also both hands at once, depending upon the song/music requirement.
But usually when starting to play the piano, its good if you learn to play the chord with your left hand and the melody with your right hand.
You should learn to play chords in both the right and left hand. However, full chords in the left hand should not be played below the C below middle C because they will sound muddy. Piano playing requires both hands to sometimes play the melody and sometimes the harmony. Independence between the hands and fingers is necessary, whether it be in the form of chords or in the form of one hand playing staccato and the other legato. It's just something you have to get used to.
