Most important practice is finger practice after hammering and strumming practice. You need to finger practice on your guitar for a softer tune any songs, easily get any chords and play them and also power up your fingers.
So the question is how doing finger practice. You need your guitar for doing it.
Firstly, you finger placed on your guitar fret board.
then on 6th fret,
Clip with your finger 1 on 1st fret.
Clip with your finger 2 on 2nd fret.
Clip with your finger 3 on 3rd fret.
Clip with your finger 4 on 4th fret.
You need to do this for 100 time for first time.
I'll post a video very soon for better understanding. wait for it. please.
