'''Merciful Intonation (MI)''' is intonation which stands in contrast to [[Just Intonation|Just Intonation (JI)]], by using [https://mathworld.wolfram.com/NobleNumber.html noble number] frequency ratios as a way of maximally avoiding coinciding harmonics. It was first systematically described by [[Margo Schulter]] and [[Dave Keenan]].
