The Bb chord
The barre chord every horn player thinks in. Jazz pianists keep it close, too. The Bb (Bb - D - F) 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 any songbook on the planet. On guitar the chord sits naturally where most players already park their hand; on piano it stacks straight up under the right hand. The page below covers the voicings worth memorising, the theory, the progressions where the Bb earns its keep, and the records that lean on it.
