Am, Dm, and Em are the minors, C, F, and G the majors, B diminished mostly skipped. The v often turns major, E7, when the song wants a harder pull home. That raised note is harmonic minor at work.

Key of A Minor FAQ

Am, B diminished, C, Dm, Em, F, and G. In practice the v is often played major or as E7 for a stronger pull back to Am.

Why does A minor use E7 if it isn't in the key?
The natural minor's v chord is Em, and it pulls home gently. Raising its third turns it into E7, which pulls to Am much harder. That raised note comes from the harmonic minor scale, and cadences borrowed it so often it became the default.
