The Abm chord

The Abm chord is an everyday minor with body. Its notes (Ab - B - Eb) form a minor triad, which is why it shows up across sad pop, indie and ballads. Songwriters pick the Abm when they want weight without melodrama, and on guitar it sits naturally where most players already park their hand. The voicings, theory, progressions and song references that follow are organised so you can skim once or settle in for the full picture.
