What is Figured Bass?

Figured bass, also known as thorough-bass or basso continuo, is a notation method used during the Baroque era in Western classical music.

It serves as a shorthand system for indicating harmonies and chord progressions to be played by accompanying instruments or performed by a keyboardist.

The technique involves using numbers and other symbols placed below the bass line to determine the desired chords and their inversions.

By interpreting these figures, musicians can improvise harmony in real time or compose appropriate accompaniments within the given framework.

Figured bass was widely employed from the early seventeenth century until the advent of modern music notation systems in the late eighteenth century.

How Did Figured Bass Originate?

The development of figured bass can be traced back to the early 17th century in Italy.

During this time, the use of polyphonic music, characterized by multiple independent melodic lines, was prevalent.

The need for a system that could guide accompanying instruments or keyboardists in providing harmonic support to these melodies became apparent.

Musicians started to notate figures beneath the bass line to indicate the desired harmonies.

These figures represented intervals above the bass note and provided instructions for creating chords. Initially, the figures were used primarily by keyboard players like organists and harpsichordists, who would use them as guidelines for improvising accompaniments.

As the Baroque period progressed, figured bass became more standardized and was incorporated into printed scores.

This enabled composers to communicate their intended harmonies more effectively to performers.

The popularity of figured bass increased across Europe and became an essential skill for musicians during this era.

Figured bass notation continued to evolve over time, with various national styles and conventions emerging throughout Europe.

Despite these regional differences, the fundamental principles remained consistent: numbers represented intervals above the bass note, while symbols indicated chord inversions or modifications.

The decline of figured bass coincided with the emergence of the Classical era and new approaches to composition and performance.

However, its influence on Western classical music cannot be overstated. Figured bass laid the foundation for later developments in harmonic theory and provided a framework that influenced composers for centuries to come.

Key Elements of Figured Bass

Figured bass consists of several key elements that are crucial to understanding and interpreting this notation system. Let’s explore these elements in detail:

• Bass Line: The bass line plays a fundamental role in figured bass notation. It serves as the foundation for the harmonies and chords indicated by the figures. The keyboardist or accompanist uses the bass line as a starting point to determine the appropriate chords.
• Figures: Figures are numerical symbols placed below the bass line, indicating the desired chords and their inversions. These figures represent intervals above the bass note. For example, a “5” figure below a bass note means that a third interval above that note should be included in the chord.
• Intervals: Intervals are represented by numerical figures placed beside specific notes within the chord progression. The figures indicate which intervals should be present above each note in relation to the bass note.
• Inversions: Inversions refer to different arrangements of chords where a note other than the root is placed in the bass position. Figured bass notation allows composers and musicians to indicate which inversions are desired for each chord by using additional symbols alongside relevant figures.
• Chromatic Alterations: Chromatic alterations involve modifying certain pitches within a chord progression to create tension or provide harmonic interest. In figured bass, these alterations are indicated through symbols such as sharps (♯), flats (♭), and natural signs (♮) placed next to specific figures or notes.
• Realization: Realization refers to the process of performing or composing a harmonic accompaniment based on the figured bass notation. It involves interpreting the figures and implementing the indicated chords, inversions, intervals, and chromatic alterations in a musical context.

Understanding these key elements of figured bass is essential for musicians or composers who wish to explore this notation system.

By grasping the relationship between the bass line, figures, intervals, inversions, chromatic alterations, and realization techniques, one can bring this historical notation method to life in their musical compositions or performances.

Developing a keen ear for recognizing intervals and melodic lines is essential for interpreting the figures accurately.

Here are some key ways in which ear training aids in understanding chords in figured bass:

1. Intervals Recognition: Ear training helps to identify the intervals between the bass note and the figures. Recognizing whether it is a third, fifth, or other interval allows musicians to determine the quality of the chord.

2. Harmonic Progression: By familiarizing oneself with common chord progressions, musicians can quickly grasp the expected harmonic motion indicated by figured bass symbols. This enables them to anticipate and respond harmonically in real time.

3. Voice Leading: Ear training facilitates an understanding of voice-leading principles, such as smooth melodic motion and avoiding dissonant leaps. Musicians trained in ear training can instinctively choose suitable inversions and voice-leading options based on their harmonic knowledge.

4. Rhythmic Perception: Figured bass figures are notated without precise rhythmic values but rely on the performers’ rhythmic sense. Ear training enables musicians to perceive suitable rhythmic patterns that complement the chord progression without conflicting with the melodic lines.

By honing their ears through consistent practice and training, musicians can enhance their ability to decipher figured bass notation accurately.

Furthermore, this heightened auditory perception allows for more nuanced interpretations of harmonic progressions, resulting in captivating performances or compositions deeply rooted in historical traditions.

How is Figured Bass Notated?

Figured bass notation involves the use of numbers and symbols placed below a bass line to indicate the desired chords and their inversions.

These figures provide information on the intervals and intervals within the chords, allowing musicians to improvise or create accompaniments on the spot.

Here are some key elements of figured bass notation:

• Bass Line: The bass line serves as the foundation for figured bass. It is notated using a standard musical staff.
• Numbers: Numbers, usually written as subscripts, indicate the intervals above the bass note that form the chord. For example, “3” may represent a third above the bass note.
• Roman Numerals: Roman numerals are sometimes used in conjunction with figures to denote specific chord qualities. For instance, “ii” may represent a minor chord while “IV” indicates a major chord.
• Accidentals: Accidentals such as sharps (#) and flats (♭) can be added to figures to specify chromatic alterations, resulting in chords outside of the key signature.
• Symbols: Symbols like “+” or “-” may be used to indicate inversions or alterations to the given figure.

For example, if a bass note is C and there is a figure “6” underneath it, it indicates a triad with an interval of a sixth above C, which could be an A minor chord in root position.

In modern music notation, figured bass is often not included explicitly but is understood by trained musicians who can interpret harmonic progressions based on contextual clues provided by the composer’s written music.

What is the Significance of Doubling Notes in Figured Bass?

In figured bass, the concept of doubling notes refers to the practice of assigning multiple voices to play or sing the same note in a chord.

This technique has significant implications for the overall sound and balance of the composition.

Doubling certain notes in a chord provides stability and reinforcement to its tonal structure.

Having multiple voices play or sing the same note, strengthens that particular pitch, making it more prominent and establishing its importance within the harmony.

One crucial consideration when doubling notes is to ensure that it does not violate any voice-leading rules or create undesirable dissonances.

For example, doubling the leading tone may cause an unresolved dissonance when progressing to a tonic chord.

Therefore, careful attention must be paid to resolve any potential conflicts that may arise from doubling specific notes.

Another aspect where doubling plays a significant role is in creating a fuller and richer texture within the music.

Doubling notes can enhance the sound by increasing its volume and adding more depth to the overall timbre.

It is important to note that not all notes in a chord need to be doubled. The decision on which notes to double depends on several factors, including voice-leading tendencies, melodic considerations, and desired harmonic effect.

Doubling certain notes in figured bass chords offers stability, reinforces tonal structure, contributes to overall harmonious balance, and enhances the richness and depth of sound.

However, proper consideration should be given to voice-leading rules and melodic considerations when deciding which notes are doubled within a chord.

How Do Chromatic Alterations Affect Figured Bass?

Chromatic alterations refer to the modification of notes to include accidentals, such as sharps (#) or flats (b), outside the key signature.

These alterations can have a significant impact on how figured bass is interpreted and realized in music.

When chromatic alterations occur in figured bass, they change the harmonic function of the chords and affect how they are resolved.

They can introduce tension and create dramatic moments in a composition. Here are some key points to consider when dealing with chromatic alterations in figured bass:

• Accidentals: Accidentals indicate the alteration of a note by a semitone. These symbols are usually written directly above or below the figured bass number associated with that note.
• Raising or lowering a note: Chromatic alterations can involve raising or lowering a note by a semitone. This changes the quality of the chord and alters its relationship with the key.
• Altered harmonies: Chromatic alterations often lead to altered harmonies, which add dissonance and color to the music. These chords may require special resolutions, adding complexity to the composition.
• Modulations: Chromatic alterations can also facilitate modulation, which is when a composition changes from one key to another. By introducing accidentals, composers can smoothly transition between different tonalities.
• Figured bass interpretation: When encountering chromatic alterations in figured bass, musicians must be attentive to these changes and adjust their playing accordingly. They need to consider how these accidentals affect the overall harmonic structure of a piece.

Chromatic alterations introduce sophisticated harmonic elements into figured bass compositions, allowing composers and musicians to explore different tonalities, create tension and resolution dynamics, and add interest and depth to their work.

How Are Seventh Chords Interpreted in Figured Bass?

In figured bass notation, the interpretation of seventh chords adds an additional layer of complexity.

A seventh chord consists of four notes: the root, the third, the fifth, and the seventh.

The bass note represents the root of the chord, while the other three notes can be represented by figures placed below the bass note. Let’s explore how these chords are interpreted:

• Major Seventh Chords: A major seventh chord is written as a lowercase “7” following the bass note. For example, a D major seventh chord would be notated as “D7.” This indicates that the third and fifth notes above D form a major third and a perfect fifth.
• Dominant Seventh Chords: The dominant seventh chord is one of the most common seventh chords used in classical music. It is notated with an uppercase “7” following the bass note. For instance, G dominant seventh would be written as “G^7.” This indicates that the third is major, while both the fifth and seventh are minor.
• Minor Seventh Chords: Minor seventh chords add a melancholic flavor to the music. To indicate a minor seventh chord in figured bass notation, you use lowercase letters for both the root and “7.” For example, an A minor seventh chord would be notated as “a7.” In this case, all three upper notes are lowered by a semitone compared to a major triad.

It’s important to mention that in classical music from this era, musicians were expected to have a strong knowledge of harmony and improvisation skills when interpreting figured bass notation.

They would use their understanding of common harmonic patterns and voice-leading principles to create interesting and appropriate accompaniments or improvisations in real-time.

Understanding how seventh chords are interpreted in figured bass notation opens up countless possibilities for creating lush harmonic textures within compositions.
