I have been trying to understand why my A minor shape barre chords and specifically A minor in 1st position sounds better with the B string tuned slightly flat. In equal temperament the minor and major intervals are mostly affected by being around 15cents off. Is this perhaps what I am hearing? I thought about this a bit but then shouldn't it be the other way since the interval from A to C is a minor 3rd which means the B should be 15cents sharper not flatter to be closer to Just intonation yet it sound better with the B tune 15 cents flat. Can someone please help me make heads or tails of this please.
