I have been trying to get better on banjo and capoing to play in different keys. I am also trying to use the number system to remember where they different scale degrees are regardless of where I capo. In this song it is asking for a flat 3rd and flat 6th but it’s actually the F and C that it should be in Am. Is this a problem on the tab on strum machine or am I misunderstanding something? Also, when it is changed to show chord names it shows the standard F and C with out the flat.
