Passing Chord
Passing chord in B? from across the circle of fifths (tritone, see also tritone substitution): B?7 About this sound Play .[1]
The circle of fifths drawn within the chromatic circle as a star dodecagon.[2]

In music, a passing chord is a nondiatonic chord that connects, or passes between, the notes of two diatonic chords.[3] "Any chord that moves between one diatonic chord and another one nearby may be loosely termed a passing chord. A diatonic passing chord may be inserted into a pre-existing progression that moves by a major or minor third in order to create more movement."[4] "'Inbetween chords' that help you get from one chord to another are called passing chords."[5]

For example in the simple chord progression in the key of C Major, which goes from I7/iii7/ii7/V7:[4]

|Cmaj7     |Em7      |Dm7    |G7   |

the diatonic (this means "from the scale of the tonic") passing chord (Dm7) may be inserted:

|Cmaj7 Dm7 |Em7      |Dm7    |G7   |

or the chromatic passing chord (Ebm7) may be inserted:

|Cmaj7     |Em7 Ebm7 |Dm7    |G7   |

or one or more secondary dominants may be inserted:

|Cmaj7  B7 |Em7  A7 |Dm7   |G7   |    (in this example, the B7 is the secondary dominant of Em7 and the A7 is the secondary dominant of Dm7)

A chromatic passing chord is, "a chord that is not in the harmonized scale"[6] For example, one or more diminished seventh chords may be inserted:

|Cmaj7  D# dim7' |Em7  C# dim7 |Dm7   |G7   |    (in this example, the D# dim7 is the viio7  of Em7 and the C# dim7 is the viio7 of Dm7)

Passing chords may be consonant or dissonant[7] and may include flat fifth substitution, scalewise substitution, dominant minor substitution, approach chords, and bass-line-directed substitution.[5] Passing chords may be written into a lead sheet by a composer, songwriter, or arranger.

As well, particularly in smaller ensembles, such as the organ trio or jazz quartet, the "comping" (chord-playing) rhythm section instrumentalists (e.g., jazz guitar, jazz piano, Hammond organ) may improvise passing chords. With large ensembles, such as a big band, the comping players may have less freedom to improvise passing chords, because the composer/arranger may have already written in passing chords into the written horn parts, which might clash with improvised passing chords played by a comping musician. The freedom of comping musicians to improvise passing chords also depends on the tempo. In a very slow ballad, if a chord-playing musician adds in an improvised diminished chord for a half a bar, this may "clash" with the melody notes or chords played by other performers. On the other hand, in an extremely up-tempo (fast) Bebop tune, a comping musician could add improvised passing chords with more freedom, because each bar goes by so fast.
