When playing a string with the right hand, it is suggested to have the finger pushing through the string. That is to say, the finger is moving inward the guitar, rather than pluck the string outward of the guitar.
This is easy for playing one string.
But how to do that on multiple strings (a chord)? It is almost impossible to push string toward the guitar, otherwise my finger will mute other strings.
seefrom 2:57, He is playing a string inward. But I don't know how to apply this to a chord.
