Modal Schemas – OPEN MUSIC THEORY (2024)

Chapter Playlist

“Mode” is a really complicated term. The article on mode in Grove Music Online (Powers et al. 2001), which is the standard academic encyclopedia for musicology, is 238 pages long and has nine authors.This means that, even if you think you already know about modes, you may want to set that knowledge aside before learning how modes are used in pop music.

This chapter discusses modes as they appear in certain schematic chord progressions in pop and rock music. Most of this information is based on the work of Nicole Biamonte (2010) and Philip Tagg (2011). After showing the function of modal harmonies as they compare to diatonic harmonies, common modal schemas will be introduced, grouped by the mode they borrow from.

Grouping modes by whether the tonic is major or minor helps with aural identification of modal passages. This grouping is represented in Example 1. The top line shows modes whose [latex]\hat3[/latex]is a major third above tonic (mi): major, mixolydian, and lydian. The bottom line shows modes whose [latex]\hat3[/latex] is a minor third above tonic (me): aeolian, dorian, and phrygian. Example 1 also illustrates what differentiates certain modes from major or minor. Each mode has exactly one pitch shown in a lighter color; this pitch is inflected when compared to major/minor. These special pitches are referred to as the of each mode.[1] These relationships are shown with the dotted slurs.

Example 1. Modes grouped by major vs. minor tonic, with dotted slurs connecting the distinctive color pitch of each mode with its major/minor counterpart.

You may already have learned about , , and in . Modal harmonies basically align in function with their diatonic counterparts, although the additional modal inflections create greater overlap between these functions. This is summarized in Example 2.

This illustration of harmonic function may help you to understand why certain modal progressions seem as goal-oriented as diatonic progressions.

Mixolydian’s color note is te([latex]\downarrow\hat{7}[/latex]), as shown inExample 3. In major-mode pop songs, the ♭VII chord is borrowed from the mixolydian mode.♭VII typically has dominant function, and you might think of it as a substitute for the traditional major-mode V chord in both the and mixolydian cadence schemas (Example 4).

Example 3. [latex]\downarrow\hat{7}[/latex] (te) is the color note of the mixolydian mode. Important mixolydian harmonies have that color note in them: v and ♭VII. (iii^ois not used.)

Example 4.The double plagal schema and the mixolydian cadence schema are two especially common mixolydian chord progressions.

Double plagal

The , which is discussed further in the blues-based schemas chapter, is also a mixolydian schema, due to the major tonic and the [latex]\downarrow\hat{7}[/latex] (te).

Subtonic shuttle

The most distinctive chord progression in mixolydian is the , ♭VII–I, or B♭–C in C major (Example 4 above). The subtonic shuttle is used continuously throughout the intro and first verse of “Tired of Waiting for You” by the Kinks (1965), where the instrumental parts shuttle between I and ♭VII throughout, while the melody emphasizes [latex]\downarrow\hat{7}[/latex] (te) as an embellishment and melodic goal (Example 5).

You may think of aeolian as equivalent to the natural minor scale. As a key or , though, aeolian and minor are different, because aeolian (as used in pop music) will prominently feature leandte [latex](\downarrow\hat6, \downarrow\hat7)[/latex]. These scale degrees give us the ♭VI and ♭VII chords, which are the signature chords of the aeolian mode. (Note the use of flat signs in label of ♭VI and ♭VII, even though they are diatonic in minor/aeolian—this is to prevent confusion with vii^o.) Aeolian schemas use one or both of these harmonies (Example 6). The ♭VI chord has subdominant function, and the ♭VII chord has dominant function.

Example 6.The subtonic shuttle, aeolian shuttle, aeolian cadence, and lament schemas are four common aeolian chord progressions.

Subtonic shuttle

The was introduced as a mixolydian progression, but the same progression can be used in aeolian. The difference is only in the quality of the tonic chord. If it’s major, then the subtonic shuttle implies mixolydian; if it’s minor, then the subtonic shuttle implies aeolian. In other words, ♭VII–i, or B♭–Cmi in C minor, is the minor version of the subtonic shuttle. This subtonic shuttle is used in the intro and verses of “Somebody That I Used to Know” by Gotye (2011, Example 7).

Aeolian shuttle

Another common shuttle in aeolian is i–♭VII–♭VI–♭VII. This progression can be understood as a between i and ♭VI, with a passing ♭VII chord along the way. This progression isfeatured clearly in the chorus of “Somebody That I Used to Know” by Gotye (2011, Example 7).

Aeolian cadence

In the aeolian shuttle schema, the consistent shuttling back and forth between I and ♭VI makes it difficult for a true cadence to be implied—a cadence means that a goal has been reached, but a circular progression like the aeolian shuttle doesn’t seem to have a goal. The ♭VI–♭VII–i, or A♭–B♭–Cmi, is similar to the aeolian shuttle, but it’s goal-oriented: it cadences on the tonic chord, and it does not tend to be used as a loop. The aeolian cadence very frequently uses a , which means all the chords are major: ♭VI–♭VII–I, or A♭–B♭–C.

The aeolian cadence has a lot of cultural associations for many people and is typically associated with success and heroism. This cadence concludes the phrases of the Fellowship Theme from Lord of the Rings(Example 8, begins at 0:27). The aeolian cadence has also been called the Mario cadence,since the well-known fanfare at the end of each level of Super Mario Bros. uses this progression; the progression is often heard as a fanfare in other video games, such as Final Fantasy. In all of these examples, the cadence concludes with a picardy third.

Lament

The has many variations, as discussedin the chapter addressing that schema. One particular flavor, i–♭VII–♭VI–v, strongly implies the aeolian mode due to the absence of a leading tone, which would imply a minor tonality, in favor of te[latex](\downarrow\hat7)[/latex], a of aeolian. This variation of the lament schema is heard in “I Don’t Like You” by Eva Simons (2012, Example 9).

Dorian is a mode that sounds like minor, but with lainstead ofle[latex](\hat6 \text{ instead of} \downarrow\hat6)[/latex], which produces altered harmonies including a major IV chord (compared to the minor iv in minor), shown in Example 10. Using a major IV chord in songs with a minor tonic is the primary marker of a dorian song, which would otherwise sound like it was minor/aeolian. The major IV chord in dorian usually has a subdominant function.

Example 10. Dorian is distinguished from the natural minor scale by its [latex]\uparrow\hat{6}[/latex] (la), which alters the quality of the IV and ii chords. (vi° is not used.)

The dorian mode is especially associated with funk, disco, and its derivative genres, where the dorian shuttle is especially pervasive. One example of many is “Dance, Dance, Dance” by CHIC (1979). Some people who haven’t listened to much music from these genres have trouble aurally recognizing the dorian shuttle and hear it instead as ii–V. Listening to a lot of funk and disco should help you learn to hear that “ii chord” as a i chord, even in more ambiguously dorian songs like Daft Punk’s “Get Lucky” (2013, Example 11).

Dorian shuttle

The alternates between a major IV chord and a minor i chord (Example 12). The overall effect of this progression is one of tonic prolongation. The upper notes of the IV harmony often form a neighboring motion that emphasizesla[latex](\uparrow\hat6)[/latex]. A common variation on the dorian shuttle is expanded to i–IV–i⁷–IV. This further expands the neighboring effect in the upper voices.

Example 12.The dorian shuttle uses minor i and major IV. It can be expanded to arch up to i⁷.

Fi[latex](\uparrow\hat4)[/latex]is the of the lydian mode, which results in a major II chord instead of the minor ii found in major (Example 13). This text refers to this chord as II♯ for clarity, with the sharp sign representing the raised third of the chord.

Example 13. Lydian is like major with [latex]\uparrow\hat{4}[/latex] (fi). This results in a major II chord. (iv° and vii are not used.)

If II♯ goes to V, as it typically does in classical music, the chord should be understood as as a V/V instead. But in pop tunes,II♯ often leads elsewhere, necessitating the II♯ label.

Very few pop songs are truly in the lydian mode all the way through the song, but many major-mode pop songs use a major II♯ chord in place of the typical minor ii, giving a brief lydian flavor while remaining overall in the major mode.

II♯can have either subdominant or dominant function, and each is used in the following two schemas (Example 14).

Example 14.The II♯ chord is the characteristic chord of lydian and is used in both of these schemas.

Lydian shuttle

The most basic lydian chord progression is a simple between II♯ and I. Identifying this chord progression correctly can be tricky: because few pop songs are truly in lydian throughout, this II♯ chord is often neutralized later in the chord progression with a IV chord or a ii chord, which means the song is overall in major, but with a brief II♯ chord. This progression can be heard with some alterations in the opening of“Sara” by Fleetwood Mac (1979).“Sara” expands the lydian shuttleto include a Ima⁷ chord to harmonize an arching melody, and it also uses a tonic pedal underneath the II♯ chord. Later on in the song, the II♯ is neutralized by the use of a . This is illustrated by Mark Spicer.

If the II♯ chord isnever neutralized, it’s possible that the chord progression isn’t really I–II♯, but another shuttle that relates roots by step. For example, Taylor Swift’s “Starlight”(2012) has verses that alternate between A and B major chords (begins at 0:26), but they are IV–V in E major, not a lydian shuttle. This becomes clear in the chorus (0:56), which is harmonized with a rotation of the . The discussed earlier in this chapter is another chord progression that relates two major chords by step. Remember that lydian is rare in pop music, and be careful when identifying this progression!

In this progression, II♯ functions as a dominant chord, leading back into the tonic with the half step between fiandsol[latex](\uparrow\hat4-\hat5)[/latex].

Lydian cadence

The most popular progression using II♯ is the lydian cadence II♯–IV–I, or D–F–C in C major. Notice that the lydian fi[latex](\uparrow\hat{4})[/latex] is immediately neutralized by the regular IV chord, replacing it with fa[latex](\hat4)[/latex]. This schema also features smooth chromatic voice leading, which may partially explain the appeal of this progression. The clearest example of this schema may be Cee Lo Green’s “Forget You” (2010, Example 15).[2]

If you are not used to playing in and listening to modes, it can be daunting to identify and distinguish modes by ear. Here is a step-by-step process for aurally distinguishing all the modes discussed here, illustrated as a flowchart in Example 16.

1. Identify the quality of tonic.

Listen for the tonic pitch. Then, listen for the whole tonic chord. Is the third of that chord major or minor? This distinguishes the major-ish modes (major, mixolydian, lydian) from the minor-ish modes (minor, aeolian, dorian).

2. Listen for [latex]\hat{7}[/latex] (ti or te).

Compare the [latex]\hat{7}[/latex] to the leading tone (ti) a half step below tonic that we typically hear in minor and major songs. If [latex]\hat{7}[/latex] is a whole stepbelow tonic (te), then it’s lowered, which means that the song is (at least temporarily) in a mode.

If you heard a major tonic and [latex]\hat{7}[/latex] is lowered (te), then you are in mixolydian.

If you heard a minor tonic and [latex]\hat{7}[/latex] is raised (ti), then you are in minor.

If your mode is not already identified, proceed to step 3.

3. Listen for other raised color notes—fi[latex](\uparrow\hat4)[/latex]in major, andla[latex](\uparrow\hat6)[/latex]in minor.

If [latex]\hat7[/latex] did not identify the mode for you, listen for other raised color notes.

If [latex]\hat{4}[/latex] is raised (fi) in a major-tonic mode, you are in lydian.If it is not, you are inmajor.

If [latex]\hat{6}[/latex] is raised (la) in a minor-tonic mode, you are in dorian.If not, you are inaeolian.
