The Ab chord
Soul writers picked Ab for its richness in the male tenor range, and Motown still echoes that. The Ab (Ab - C - Eb) is a major triad, which is why it sounds bright and stable. Writers pick it for a confident landing point, and you can find it across verse-chorus pop and singalong folk. On guitar the chord sits right under the fingers in open position; on piano it stacks straight up under the right hand. The page below covers the voicings worth memorising, the theory, the progressions where the Ab earns its keep, and the records that lean on it.
