Chord progressions in Bb major

Pick Bb major for a singalong moment. It is the brass-band home key, friendly to horns and saxes. Its tonic chord carries stability, and the rest of its diatonic chords arrange themselves around that gravity. Concert pitch for nearly every brass instrument, which is why so much funk and big-band sits here. The chord ladder, the most-used progressions, real songs that lean on them, and the borrowed chords that darken the bridge for one bar when the song needs a tonal sidestep are all in the sections below.
