32.1 BORROWED SCALE DEGREES IN MINOR KEYS

From the beginning, minor scales have borrowed scale degrees from major scales: leading tone (^7) is appropriated to provide a strong motion to tonic, and ^6 is raised (borrowed from the major) to provide a smoother motion to the leading tone (avoiding the A2 that would happen without raising it). This is a commonly accepted process.

Even ^3 can be borrowed from major, in the Picardy third. The end result is that all the pitches of major keys are available in minor. This chapter is about the reverse process.

32.2 BORROWED SCALE DEGREES IN MAJOR KEYS

It is a small step to allow scale degrees to be borrowed from the minor, which can be formed into BORROWED CHORDS. These borrowed scale degrees change the quality of the triads and tetrads.

The change in quality of these sonorities must be shown by the Roman numerals. In addition, their special derivation will be indicated with an asterisk (*) added to the left of the Roman numeral. The asterisk is a type of footnote which states "this harmony is created by the process of borrowing scale degrees from the parallel minor key". Every diatonic sonority can be altered through this process:

Notice that the borrowed mediant, the borrowed submediant, and the subtonic all have an accidental placed before the Roman numeral. In each of these cases, the root is one of the borrowed scale degrees and is a different pitch from the diatonic roots. This change of root requires a label.

32.3 FUNCTION OF BORROWED CHORDS

The function of borrowed chords is the same as the diatonic counterparts. A minor tonic (borrowed) does the same as a major tonic (diatonic), the diminished supertonic (borrowed) is the same as the minor suptertonic (diatonic), and so on. They provide a rich resource of color but do not interrupt the flow of harmonic progression.

Two borrowed chords, however, do not work in the manner indicated by their Roman numerals. The minor dominant and the subtonic do not serve the dominant function, just as presented in Chapter 19. The presence (or absence) of a leading tone makes the difference:

• With the leading tone, major dominant and leading tone move towards tonic (defining the "dominant" function)
• Without the leading tone, minor dominant and subtonic move away from tonic (defining the "non-dominant" function)

32.4 VOICE LEADING OF BORROWED CHORDS

Chromatic pitches always have a strong inclination to resolve in the direction of their change: sharps and naturalized flats generally need to resolve up by step (as with tonicizations), flats and naturalized sharps generally need to resolve down by step. Therefore, lowered ^3 tends to resolve to ^2 (although on occasion it might move to ^4), lowered ^6 to ^5 (although on occasion it might move to lowered ^7), and lowered ^7 to ^6. Sometimes this motion is delayed, but ultimately it will resolve.

32.5 CHROMATIC VOICE EXCHANGE

The possibility of having two versions of scale degrees offers the possibility of voice exchanges in a chromatic context.

These relationships are also called FALSE RELATIONS (or CROSS RELATIONS) and although they are rare, they can be used as a prolonging device.

32.6 CHROMATIC HARMONIC ANALYSIS

As harmonic vocabulary begins to expand with chromatic procedures such as borrowing, it is important to develop a strategy for providing a Roman numeral analysis. The following steps are suggested:

1. Stack the sonority into thirds
2. Identify the quality
3. Identify the scale degrees (particularly the chromatic ones)
4. Using steps 2. and 3., begin categorizing the possibilities
5. Examine the context (where does it come from, where does it go)
6. Provide the most likely label

1. The sonority is F# - A - C - E
2. The quality is dm7
3. The scale degrees are Re - Fa - Le - Do
4. The root of ^2 indicates supertonic, the lowered ^6 indicates a borrowed chord
5. It comes from a tonic prolongation and moves into a cadence
6. It is a borrowed supertonic 7, in first inversion

Do the same thing again with the following example:

1. The sonority is B - D - F - Ab
2. The quality is dd7
3. The scale degrees are Di - Mi - Sol - Te
4. The root of raised ^1 indicates a leading tone motion to ^2, the dd7 also indicates a leading tone 7
5. The chord comes from a tonic substitute and moves to supertonic
6. It is a leading tone 7 tonicizing the supertonic, in second inversion

CURRENT CHROMATIC VOCABULARY:

This chromatic chart was first presented in Chapter 22 and will continue for the next few chapters as chromatic vocabulary is expanded. Only chromatic scales degrees are included, and they can occur in any voice.

• Raised: ^1, ^2, ^4, ^5, and ^6 (^3 and ^7 cannot be raised)
• Lowered: ^7, ^6, ^5, ^3, ^2, and ^1 (^4 cannot be lowered)

It is organized by general categories (tonicizations and borrowed chords) that show all the chromatic scale degrees, and by sub-categories that show only the scale degrees for that particular item.
