Many guitarists consider the H chord (in its basic setting) to be one of the hardest chords. The main reason for this is not very comfortable fingering, which requires a lot of physical effort to create an even sound.
Instructions
Step 1
Bring the F and Hm chords to perfection. They (like the H) are set using the barre, but much easier and more convenient in fingering. "C" is a relatively uncommon chord, and is not so common in songs, so there is no point in rushing to master it. Do it only when your index finger is no longer uncomfortable with all the strings and the sound gets rid of the bounce.
Step 2
Master standard fingering. It looks like this: the barre at the second fret, the second, third and fourth strings are clamped at the 4th fret. Formally, this combination of fingers is called "small major barre" and is played on five strings out of six, the sixth is simply muffled. Some guitarists, having learned about this, clamp the first and fifth strings with their index finger, and the sixth simply "touch from below." This position is "unstable" and should be used only if there is no way to play differently (for example, the size of the palm does not allow). The method is really quite convenient, but it should not be overused.
Step 3
Don't put your fingers on top of each other. If you do this, then (especially on a narrow neck) you will simply interfere with your own chord. The 4th fret is large enough, so it is wise to use the full width provided: press the strings with a ladder. The second is at the fifth fret, the third is in the middle, and the fourth is near the fourth metal nut. Note that the little finger can push quite lightly, while the middle finger will have to exert considerable force.
Step 4
Apply other fingerings. There are at least 3 options for staging the "B" chord, and each can be useful in a certain situation. For example, if you play the barre throughout the song and you feel uncomfortable jumping towards the end of the fretboard, you can play an F chord from the 7th fret - this will also be an H chord. Other fingerings are more complex and are used to give the composition a specific sound.
