When a song is in a minor key, how do you approach the song? Are you think Major or are you thinking Minor with the minor chord being the 1?
Example:
In Ab, are you just thinking in Ab with the 6th (F) being the minor or do you think it as the F being the 1?
To answer your example, if you're in
F MINOR, then yes, you'd apply the chords you'd play in Ab Major.
Something that I like to do is treat F like the 2 of Eb Major or the 3 of Db Major (or if you want to take it out a little even the 7 of F# Major). This works because F is minor in Eb and Db and Diminished (nice!) in F#.
You have to eventually come back to playing it as the 6 of Ab Major, but it sounds nice to change things up a little.
