What Note Would You Add To Make This An F Minor Triad Brainly
II. Diatonic Polyphony and Functional Harmony
13. Triads
In Affiliate 12 nosotros outlined the diverse considerations surrounding interval progressions—the series of pitch combinations that result when melodic lines sound simultaneously. Our word so far has been limited to musical textures consisting of but two voices. Chapter xiv volition expand this discussion to include progressions with more than two voices, simply let us preview what a four-phonation texture might await and audio like here:
Instance thirteen–1. Johann Joseph Fux, Gradus advert Parnassum, Fig. 170.
This short piece—really a sample exercise from a limerick manual by Johann Joseph Fux—consists of four voices in F major. For the about part, each pair of voices follows the conventions discussed in Chapter 12. Given that all 4 voices follow the same simple rhythm, nosotros may describe the passage as a series of polyphonic sonorities. The following example reduces these sonorities to their unique pitch classes and arranges each of them on a single staff with the noteheads every bit close together every bit possible:
Example 13–2. Reduction of Johann Joseph Fux, Gradus ad Parnassum, Fig. 170.
With the exception of the last measure, all of the sonorities in Example 13–2 look and sound remarkably similar: iii-note stacks of thirds differing only in their position on the staff. Harmonies such as these are known every bit triads and they appear in virtually every piece of tonal Western art music.
In this chapter we will discuss the structure of triads and the dissimilar types one encounters. We as well volition draw a widely-used arrangement for labeling triads in a key using Roman numerals and the various belittling applications in which these labels come in handy.
A chord or harmony is a musical sonority consisting of two or more pitches. (Nearly people reserve these terms for sonorities with iii or more than pitches, though an interval may also be considered a blazon of chord.) A triad, equally the name implies, is a type of chord made upwards of three unique pitch classes. Non all three-notation chords are triads, however. For a chord to be a triad, the pitches contained therein must combine to create specific intervals.
When written as closely every bit possible on a staff, the 2 upper notes of a triad must grade a third and a fifth—or compound third and fifth—above the everyman note. The three chord members have names that represent with their position in the chord:
Example 13–3.
When a triad is written in the manner shown to a higher place—as a stack of thirds with the three notes occupying consecutive lines or spaces on the staff—the lowest note is called the root. The name is easy to remember since the root provides a stable back up for the remainder of the chord, but like the roots of a tree. The other notes are named according to the interval they form above the root: the third is a third to a higher place the root and the fifth is a 5th above the root. These names stay with their respective pitch-classes, regardless of how the chord is voiced (arranged on the staff):
Example xiii–four.
This chord has the same pitch classes as the one in Example 13–3. Therefore, G is however considered to be the root. Likewise, B and D are still the 3rd and fifth, respectively, even though they are now positioned below the root.

Answer
Although at that place are only 3 chord members in a triad, this type of harmony frequently appears in textures with more three voices. (Retrieve the example from the introduction to this affiliate, where a series of triads appears as a result of combining four melodic lines.) When a chord member appears more than once in a voicing, we say that it has been doubled. The following example shows the same triad as above but here voiced in SATB format (come across Affiliate 5):
Example xiii–5.
Despite the fact that there are four voices, the chord in Example xiii–5 is nevertheless considered a triad. It presents four pitches, but simply three unique pitch classes and in this regard is the same as Example 13–3 and Example 13–iv. Observe that both the bass and soprano take G, the root of the chord. Nosotros would say, then, that the root of the chord has been doubled.

Answer
Equally with intervals, triads come in different qualities. Triads may be major, minor, macerated, or augmented. To determine the quality of a triad, one must consider the qualities of the intervals contained therein.
The post-obit case shows a major triad and a modest triad built on the same root:
Case 13–six.
a. major triad
b. minor triad
Both of the triads in Example thirteen–6 are consonant and stable. This is largely due to the fact that both chords feature a perfect 5th betwixt the root and fifth. The difference between major and minor triads lies in the quality of the interval from the root to the tertiary. In a major triad, the interval from the root to the tertiary is a major third; in a minor triad it is a small 3rd.
In improver to the intervals formed with the root, there is another interval heard between the third and the 5th. Discover that in major and minor triads, the quality of this third is the opposite of the quality of the whole chord. In other words, a major triad has a pocket-size third between the third and the fifth and a minor triad has a major third in the same identify. In improver to thinking of a triad as consisting of a 3rd and a fifth to a higher place a root, it is also helpful to think of information technology equally two thirds stacked 1 on top of the other.
Note: A tertian harmony is one that is constructed as a stack of thirds. Triads are tertian harmonies. If one were to add another third on top of a triad, that note would be a seventh above the root. This blazon of tertian harmony is discussed in Chapter 18.
Triads are named according to their root and quality. The triad in Example 13–6a, for example, is a Yard-major triad and the triad in Example xiii–6b is a G-minor triad. Triads may be built on any note. The following example shows an E b-major triad:
Example thirteen–seven.
Detect that an E b-major triad requires two accidentals to preserve the exact interval qualities shared by all major triads.
A triad with a minor third and a diminished fifth above the root is considered diminished. The post-obit instance shows a Yard-diminished triad:
Example thirteen–8.
This triad is much more anomalous than the major and pocket-sized triads heard above. It has the same minor tertiary between the root and tertiary equally the minor triad, but here the perfect fifth has been replaced with a anomalous tritone: a diminished fifth. (Y'all may also retrieve of it as a stack of two pocket-size thirds.) Every bit a event, this chord is much less stable. We will hash out this chord at length in Chapter 16.
A triad with a major third and an augmented fifth in a higher place the root is considered augmented. The following example shows a G-augmented triad:
Example xiii–9.
Like a macerated triad, an augmented triad is anomalous. Similar a major triad, information technology has a major 3rd between the root and third. But hither we notice another major third stacked on acme, making the framing fifth augmented. Of the iv triad qualities, augmented triads are the outliers. They have a very peculiar sound and, every bit we will encounter momentarily, they differ from the other triad qualities in that they cannot be constructed using but diatonic pitches. As a outcome, they appear far less frequently than major, pocket-size, and diminished triads. We will look at a few examples of this rare chord in Chapter 34.
Annotation: Triad names are often abbreviated. An uppercase pitch letter proper noun with an uppercase "1000"—or an capital letter pitch letter proper noun past itself—indicates a major triad ("GM" and "G" are curt for "Chiliad major"). An uppercase pitch letter name with a lowercase "grand"—or a lowercase pitch letter of the alphabet proper name past itself—indicates a minor triad ("Gm" and "g" are short for "Thousand minor"). A raised degree sign ( o ) attached to pitch letter name indicates a diminished triad ("G o " is short for "G macerated"). Finally, a raised plus sign (+) attached to a pitch letter name indicates an augmented triad ("G+" is short for "Chiliad augmented").
Table 13–1 summarizes the intervallic content of the iv triad qualities:
Tabular array 13–one
| Triad quality: | Interval betwixt root and third: | Interval betwixt third and 5th: | Interval betwixt root and fifth: |

It is important that you be able to speedily and accurately identify or construct triads. I useful step in acquiring this skill is memorizing all of the natural triads—that is, all of the triads that tin be constructed using the white keys on a piano keyboard.
Consider, for example, a triad congenital on C using only natural pitches, no sharp or flat pitches. The following example shows such a triad in staff notation and shows the location of the corresponding piano keys:
Case thirteen–ten
a.
b.
This chord—congenital using the pitches C, E, and Chiliad—is a C-major triad. With this in mind, it is very easy to place the following chord:
Example thirteen–xi.
a.
b.
This triad is very similar to the C-major triad shown above. It has the aforementioned root and fifth. The only difference is that the third lies a semitone lower, making the interval between the root and third a pocket-sized tertiary. Past comparing it with the C-major triad shown to a higher place, it is clear that the chord in Case xiii–11 is a modest triad.
The following table summarizes all of the natural triads:
Tabular array 13–2
| Root: | Third: | 5th: | Triad: |
|---|---|---|---|
| A | C | E | A pocket-sized |
| B | D | F | B diminished |
| C | E | Thou | C major |
| D | F | A | D pocket-sized |
| E | G | B | E pocket-size |
| F | A | C | F major |
| G | B | D | Chiliad major |
Notice that all of the natural triads are either major or pocket-sized with the exception of one: the natural triad congenital on B is diminished. Detect, also, that there are no augmented triads in Tabular array 13–2. An augmented triad will always require at least one accidental.
Activity thirteen-v
In each of the post-obit exercises, you will be asked to identify the chord that results from adding one or more than accidentals to a natural triad.

The natural triad built on D (D, F, and A) is minor. What chord would result from lowering the root one semitone?
Hint

Answer
Of the three chord members, the root of a triad is considered to be the strongest and most essential. In terms of voicing, the bass note—the lowest sounding notation—is often heard as supporting the notes that appear above it. When these two things marshal—that is, when the root of a triad appears in the bass—we tend to hear the chord as being very grounded: the about stable chord member is in the near stable function of the chord. Of form, the third and 5th may appear in the bass equally well, in which cases the chord will audio insufficiently less stable.
The position of a chord is determined by the chord member sounding in the bass. Since there are 3 chord members in a triad, there are three possible positions. A triad with the root in the bass is said to be in root position. Triads with the third or fifth in the bass are said to exist inverted since the root appears college upward with at least ane of the chord'due south intervals inverted. A first inversion triad has the third in the bass while a 2d inversion triad has the fifth in the bass.
The post-obit example shows all three positions of a C-major triad.
Example 13–12.
Notice that nosotros have as well included a small stack of Standard arabic numbers (1, two, iii, etc.) nether each chord. These numbers—collectively refereed to as figured bass—signal the sizes of the intervals appearing above the bass notation and, therefore, the position of the chord. (See Chapter 21 for a more in depth discussion of figured bass.) Each chord position has a unique set up of numbers. A root position triad has the root in the bass with the other notes of the triad forming a 3rd and fifth to a higher place it. The consummate figured-bass signature is thus 5 / 3 . A kickoff inversion triad inverts the interval between the root and tertiary of the chord (C and E in this instance) to a sixth and retains the third betwixt the tertiary and the 5th (Eastward and Yard), hence the figured-bass signature 6 / 3 . A 2d inversion triad inverts both of the original intervals and therefore contains a fourth and a sixth above the bass, thus the figured-bass signature 6 / iv . You will frequently encounter triads referred to by their interval content ("6-iii triad" instead of "start-inversion triad").
Annotation: For the sake of clarity, each of the chords in the example above is written using only three notes. Doublings have no bearing on the position of the chord. Similarly, the relative locations of the upper voices practice not affect the chord's position. If the E in the root-position triad higher up was written higher than the G, it would even so be a root-position triad.
Activity 13-6
In this activity, you lot will be presented with a series of triads in SATB setting. For each practise, cull the advisable figured bass signature ( 5 / 3 , 6 / 3 , or half dozen / 4 ) to represent the inversion of the triad.

Figured bass originated as a shorthand technique, and then the figures used to betoken chord inversions are often abbreviated. Root-position triads are and then common that they are generally represented with no effigy at all. They are as well occasionally indicated with merely 5 (the tertiary higher up the bass is assumed). The following example shows three ways of representing a C-major triad in root position:
Example 13–xiii.
Starting time-inversion triads also appear quite oftentimes, so the 6 / 3 figure is frequently abbreviated to merely 6 , with the third taken for granted. Both of the figures in Example xiii–14 can be used to indicate a C-major triad in first inversion:
Example xiii–14.
2nd inversion triads are always represented with half dozen / 4 .
The following extract shows how figured bass tin can be used to bespeak inversions:
Example 13–15. Reduction of Johann Sebastian Bach, "Nun danket alle Gott" (BWV 386), mm. 1–2.
The first iii chords are all A-major triads. The starting time and second are both in root position even though the bass leaps up an octave. As the bass continues to bound upwards from A to C # in the first total measure, the figures change from 5 / 3 to 6 / 3 indicating the progression from a root position A-major triad to a first inversion A-major triad. A similar situation happens with the two D-major triads on beats iii and 4 of that same measure.
The following table summarizes the various figures for triads and lists the common abbreviations:
Tabular array 13–iii.
| Position: | Figured Bass: | Mutual Abbreviations: |
|---|---|---|
| root position | v / 3 | 5 or no figure |
| offset inversion | six / 3 | vi |
| second inversion | 6 / 4 |
Notation the absence of half-dozen / 4 chords in Example 13–xv. Second inversion triads are considered unstable in this style of music and therefore appear far less frequently. We will discuss second-inversion triads at greater length in Chapter 23. You should yet exist familiar with all three rows of figured bass symbols in Table xiii–iii.
Equally with intervals, information technology can be helpful to recollect about triads as they relate to a scale or cardinal. A C-major triad, for case, is built using scale degrees [latex]\hat1[/latex], [latex]\hat3[/latex], and [latex]\hat5[/latex] of the C-major calibration:
Example 13–16.
Notice the similarity in sound betwixt the C-major calibration and C-major triad. Every major and minor triad shares this relationship with the respective key. Only exercise non let this relationship pb you to confuse scale degrees and chord member names. The terms root, 3rd, and fifth refer to the position of a note within a triad and do non necessarily stand for with scale degree numbers. In fact, nosotros tin can build triads using any calibration degree as the root. The post-obit case shows all of the diatonic triads in C major:
Instance 13–17.
In Chapter 6, we discussed several different means of labeling calibration degrees. The set up of scale degree names can also be used to label chords in the context of a cardinal:
Case 13–eighteen.
These labels are particularly useful when talking about how various chords relate to the key. We may utilize them, for case, to point out that an E-minor chord is the mediant of C major. These terms are similarly used for describing cardinal relationships. One could say, for example, that the key of G major is the ascendant of C major.
Minor keys have a different ordering of chord qualities:
Example thirteen–19.
You lot may notice that with regard to the qualities of the triads, the pattern in minor is the same equally major, but showtime in a unlike identify. (Get-go with the mediant in small, y'all'll discover the same pattern of qualities as begins on the tonic in major.) This similarity is a result of the relationship between relative keys. Nosotros will return to small-scale-key chord qualities in Chapter 17, when we discuss common alterations made to the natural minor scale.
Activity 13-7
The following questions will exam your knowledge of how sure chords relate to keys.
Exercise 13–7a:

Hint

Answer
B b major is the subdominant of F major.
Roman numerals are a useful, autograph way of naming and analyzing chords, and of showing their relationships to a tonic. They are a pop tool in the harmonic analysis of tonal music because they convey two vital pieces of information in a single symbol, indicating both the root and the quality of a chord. The number symbolized by the Roman numeral corresponds to the calibration degree serving every bit the root of the chord. The quality is indicated by the example of the Roman numeral: upper example indicates major triads, lower case minor triads. As discussed above, a raised degree sign ( o ) attached to a lower-case Roman numeral indicates a diminished triad and a raised plus sign (+) attached to an upper-case Roman numeral indicates an augmented triad.
It is imperative that you familiarize yourself with the qualities of diatonic triads in both major and small-scale keys. The following instance shows the pattern of major, minor, and diminished triads in a major key:
Example 13–20.
As you can see, the triads built on scale degrees [latex]\hat1[/latex], [latex]\hat4[/latex], and [latex]\hat5[/latex] are major (I, Iv, and Five), while the triads built on scale degrees [latex]\hat2[/latex], [latex]\hat3[/latex], and [latex]\hat6[/latex] are pocket-size (ii, three, and vi). Notice that the triad congenital on scale degree [latex]\hat7[/latex] (vii o ) is the only diminished triad of the group.
For easy demonstration, Instance thirteen–20 is in C major, but the pattern of triad qualities is identical for all major keys. Roman numerals e'er refer to the scale degrees of the key at hand. If Example 13–20 were transposed to Due east major, the Roman numerals would stay the same:
Example 13–21.
Minor keys, on the other hand, have their ain design of major, minor, and macerated triads:
Example thirteen–22.
Again, the pattern in small is the aforementioned as major, but first in a different place. (First with Iii in minor, you'll discover the same blueprint of qualities as begins on I in major.)
Note: The Roman numeral system described hither is just one of several unremarkably used methods for identifying chords. In other texts y'all may encounter analyses that employ just uppercase Roman numerals. In such cases, it is assumed that the reader will be familiar enough with the qualities of diatonic chords that they will know that "Half dozen" in a major key indicates a small triad unless otherwise specified.
Another widely-used system—the so chosen "Nashville number" arrangement—uses Arabic numerals instead of Roman numerals. In the context of G major, for instance, "4" is used to indicate a C-major triad. Many jazz musicians are familiar with a more straightforward system. There, chords are specified by their pitch content alone with no reference to the calibration degree on which they are built. A "D," for case, indicates a D-major triad. Actress messages and symbols are used to indicate other chord qualities: "Em," for example, refers to an E-pocket-size triad. This organization is sometimes called the "slash chord" system in reference to how inversions are indicated. If the chord is not in root position, a slash followed past a notation letter proper noun is used to specify which chord member is in the bass. "Em/G," for case, refers to an Due east-minor triad in which G is the lowest sounding note—in other words, an E-minor triad in first inversion.
Switching from one system to another tin be confusing at start. But with patience and perseverance you volition find that all of these systems can exist both useful and intuitive. Each method has advantages and disadvantages for unlike kinds of music and no system is universally perfect.
As we accept seen, Roman numerals are succinct and informative in themselves: they bespeak both the root and quality of a given harmony. Across this, a Roman numeral may be combined with a figured bass signature to provide an even more than thorough summary of a chord. The figured bass, by specifying the intervals heard above the bass note, indicates the position of the triad while the Roman numeral indicates the scale caste of the root and the quality of the chord. The following instance shows a outset-inversion D-major chord in the context of Grand major:
Instance thirteen–23.
Here, the Roman numeral tells us that this is a dominant chord in G major since V corresponds with scale degree [latex]\hat5[/latex]. We know that this is a major triad since the Roman numeral is written with an uppercase letter. Finally, we know that the bass note (F #) is the third of the chord since half dozen (short for vi / 3 ) is the figured bass signature for a first-inversion triad.
This combination of analytical tools allows us to summarize the harmonic content of a slice or passage very efficiently. Consider the post-obit analysis:
Example 13–24. Giovanni Pierluigi da Palestrina, Missa Inviolata, Iii. "Credo in unum Deum," mm. 73–81.
This passage is in the key of F major. A Roman numeral has been placed under nearly every bass note. The passage begins with an F-major triad: F, A, and C with the root doubled in the alto. This is a tonic chord in the key of F major and so has been labeled "I." The D-minor and A-minor triads that follow, built on calibration degrees [latex]\hat6[/latex] and [latex]\hat3[/latex] respectively, have been labeled "vi" and "3" for the same reasons. The offset chord in thousand. 75 is another pocket-size triad, though here the root is in the soprano voice with the fifth in the alto and the tertiary doubled in the tenor and bass. Since the root (Chiliad) is calibration degree [latex]\hat2[/latex] in F-major and since the bass annotation is the third, the chord has been labeled ii 6 .
Note: Annotation that some of the notes—we have put them in parentheses—do not vest to the chord with which they sound. They are melodic embellishments that enliven the musical surface. These nonharmonic tones are discussed in greater detail in Chapter 15.
Aside from efficiently cataloging the pitch content of each chord, the Roman numerals allow the states to brand a number of quick observations about the whole passage. The first set of chords—up to the rest at the finish of m. 76—begins with the tonic (I) and ends with the dominant (5). The second prepare of chords (mm. 77–81) does the contrary: it begins with a long V chord and works its mode back to I. Most of the chords are in root position, adding to the excerpt's stability and finality. Some chord progressions are mutual to both sets of chords, including two–IV and 4–Five.

A triad is a type of chord consisting of 3 unique pitch classes. When the three pitches are written on consecutive lines or spaces on a staff, nosotros refer to the lowest note as the root and the upper notes as the tertiary and fifth, based on the intervals they course higher up the root. In that location are many means to vox a triad: the positions of the three chord members may be rearranged and whatsoever of them may be doubled. The names of the chord members, however, stay with their corresponding pitch classes, regardless of how the chord is voiced.
Like intervals, triads come in different qualities. Major and pocket-size triads are consonant. They characteristic a perfect fifth between the root and chordal 5th and are named after the major or small-scale tertiary between the root and chordal third. Diminished and augmented triads are anomalous. A diminished triad has a minor third and diminished fifth in a higher place the root while an augmented triad has a major third and augmented fifth in a higher place the root. Of the four triad qualities, augmented triads are outliers since they cannot exist synthetic using simply diatonic pitches and volition therefore always crave at least one accidental. Major, minor, and diminished triads, on the other paw, can be constructed using only white (natural) keys on a pianoforte and announced in every major or small key.
The position of a triad is adamant by the bass voice. If the root is in the bass, the chord is said to be in root position. If the third or 5th is in the bass, the chord is said to be in first or 2d inversion, respectively. We point a chord'southward position with a figured bass signature—a stack of Arabic numerals respective with the sizes of the intervals heard above the bass. The effigy 5 / 3 (or five or no figure at all) is used to point a triad in root position, and six / 3 (or 6 ) and half dozen / 4 are used to stand for triads in, respectively, offset and 2nd inversions.
Roman numerals are a convenient means of naming and analyzing chords. They concisely convey important information. The numbers symbolized by Roman numerals bespeak the calibration degrees on which chords are congenital. "I" indicates a chord congenital on [latex]\hat1[/latex], "ii" a chord congenital on [latex]\hat2[/latex], and and so on. Furthermore, the example of the Roman numeral indicates the quality of the chord. Figured bass numerals may be added to Roman numerals to provide an even more thorough account of the content and structure of any given triad.
