Related ii – Anthropology

Related ii chord: a ii(7) chord that occurs before a secondary dominant and is in the key being tonicized. The inclusion of this chord creates a (ii-V)/x progression.

Below we will look at another example of a related ii chord – “Anthropology” by Charlie Parker.

“Anthropology” by Charlie Parker is a contrafact of Gershwin’s “I Got Rhythm.”

A contrafact is a musical work based on a prior work. In jazz, this usually means that the harmonies of the two tunes are very similar, if not exactly the same.

A chords only version of the piece is shown below.

Like “I Got Rhythm,” “Anthropology is in a 32-bar song form (AABA). We will look at the final A section of the piece – mm. 19 to the end of the head.

Analyzing everything we can gives us the analysis below.

Most chords are diatonic to either Bb major or minor.

Note a couple of non-diatonic chords which are chords that we already know:

First, the secondary dominant in m. 20, the V7/ii (G7) that resolves normally to the ii7 (C-7).

Second, the use of the IV7-bVII7 progression in m. 27 which is not quite in either major or minor but can be thought of as a type of backdoor progression.

The chords in purple boxes are examples of related ii chords.

First let’s look at m. 23, the F-7 — Bb7 chords that go to Eb7 in m. 24.

Anthropology, mm. 19-end

The Bb7 chord in m. 23 can be thought of as a V7 of the Eb that follows (the IV in the key of Bb). The F-7 is the ii7 in this same key of Eb and so is the related ii. Therefore, the F-7 — Bb7 is the ii7-V7 progression in the key of Eb and is thus analyzed as such (see example below).

Anthropology, m. 19-end

Next, Let’s look at the chords in m. 25 – the D-7 — G7 that proceeds to the C-7 in the next measure.

The G7 in this measure acts as a dominant 7th chord to the C-7 that follows. It could be analyzed as a V7/ii (as in m. 19). However, in this case, it is preceded by a D-7, a ii7 in the key of C. This D-7 is the related ii of the G7. Therefore, it is analyzed as below to show the (ii7-V7) relationship of the C-7 that follows.

More examples that include related ii chords are presented in the following lessons.
