About minor chords
The minor chord swaps the major third for a minor third: 1 ♭3 5. That single semitone makes the sound darker, softer and more inward. Minor does not have to mean sad: in funk, Latin music or rock it can sound tough or cool, and it can end a piece just as convincingly as a major chord.
It is the tonic of minor keys (i) and appears on ii, iii and vi in major keys. Typical moves: i iv V (the major V borrowed from harmonic minor), i ♭VI ♭VII, and vi IV I V. Every major chord has a relative minor a minor third below that shares two of its notes.
Start with the open shapes Em, Am and Dm. The movable shapes grow out of them: the E-shape minor barre (root on the 6th string) and the A-shape minor barre (root on the 5th string). Compared with the major barre, only the third moves, one fret lower, so switching between major and minor is quick once your barre is solid.
Reading the symbol wrong is common: 'm' or '-' means minor, while 'M' or 'maj' means major, so Am and AM are different chords. On guitar, the minor third often lies on a string that is easy to mute in a barre. And m is not m7: the 7 adds a fourth note, the minor seventh.
