How it is built

Bb7 adds a flattened seventh above the major triad. The tension in that seventh wants to resolve — often to a chord a fourth above.

Common musical function

As a dominant chord, Bb7 creates forward motion in progressions and is one of the most common seventh chords in pop, jazz, and blues.

Beginner practice advice

Practice Bb in root position until the shape feels automatic, then work through the first, second, and third inversions. Use the audio button to check your voicing, and drill short changes to neighboring chords in the same key.

Moving into and out of the chord

Look for shared notes with nearby chords in the key — keeping a finger on a common tone makes changes smoother. Bb Major and Bb9 are good starting points for short practice loops — see the full related chords list below for more.
