B-flat Major 7th Chord theory and function

The major 7th adds the note a half step below the octave, which gives the chord a soft, open sound with a little friction in it. In Baroque and Classical music it appears as a passing seventh inside a sequence, and in Romantic and Impressionist music it is used as a color chord on the tonic and the subdominant.

The B♭ major 7th chord is the tonic (Imaj7) in B♭ major and the subdominant (IVmaj7) in F major. In minor keys, it is the mediant (IIImaj7) in G minor and the submediant (VImaj7) in D minor.

The cadence to recognize is ii7 – V7 – I. In B♭ major that is Cm7 – F7 – B♭maj7, where the tonic is colored with its seventh. In a sequence the seventh leans down by step into the next chord, and in a color chord it is left hanging for a moment before the music moves on. Try playing B♭ and then B♭maj7 and listen to what the added note does.
