The chord of A minor is not a difficult piano chord to play. It does not represent any large stretches. You should find this chord fairly simple to play and remember.
Do practice changing between this chord and others. Especially practice-changing between C F G and A minor in all directions and between all three of the other chords.
Many songs use C F & G major and often use A minor as well so it is good to be able to play with all of them.
these chords and their counterparts in the other keys are often used in the 12 bar blues arrangements. They are not always played in the same order. That is why I suggest that you practice playing changing from all three of three chords and A minor as you will need to, depending on the order the other chords are played in to suit the song.
