The Cm chord
The Cm chord is a chord that quiets a room. Its notes (C - D# - G) form a minor triad, which is why it shows up across indie rock and slow-burn ballads. Songwriters pick the Cm when they want weight without melodrama, and on guitar it sits naturally where most players already park their hand. The first chord in Adele's Hello and a thousand other ballads. The voicings, theory, progressions and song references that follow are organised so you can skim once or settle in for the full picture.
