Basso Continuo Notation of the Baroque Period
Abstract
In the medieval and renaissance eras, many forms of music were monophonic and for religious purposes. Composers performed music with little accompaniment to instruments such as the harpsichord or a cello. Tonal music was also more accepted and applauded in society than instrumental music. In the long run, polyphonic chant developed, which started as monophonic songs sung in third and fifth notes, and later, Baroque music evolved (Treitler, 1992). In the Baroque period, composers made improvements to incorporate musical symbols and numbers that directed the players, which later became the notation in today's contemporary world. In this regard, the use of figured bass and basso continuo musical notations set the foundation for Baroque music and all music after the era. Music notation is a system used to visually represent music sung by the human voice or played with instruments, whether printed or written, including the notations for durations of the absence of sound, such as rests. The basso continuo notation indicated notational symbols of baseline, incorporated in music accompaniments by different instruments such as the harp, violin, stringed keyboards, and harpsichords. This write-up will expand on the history of the musical notation system, basso continuo and figured bass musical notation, and famous composers of basso continuo in the Baroque era.
History and Background of Music Notation System
The essential elements of music notation sounds include volume, pitch, and duration. Pitch refers to the frequency properties of the sound wave, whereby a higher pitch is associated with a high sound wave frequency. On the other hand, volume is the intensity of the sound, which is the most vital characteristic of music. Conversely, duration refers to the tempo and rhythm of the sound. In this regard, music notations seek to assign standardized music symbols to the musical elements so that individuals can play and recreate music even if they have not heard it before. The crotchets, staves, and quavers notations in the contemporary world are the product of centuries of refinement and innovation. The history behind musical notation runs pretty deep, whereby as the bars and dots seem simple to the eye, they convey complex language to convey creative ideas.
The Babylonians created the earliest forms of music notation about 1400 BCE, found in cuneiform. The tablet comprises instructions from the composers to players made in harmonies of thirds using a diatonic scale. On the other hand, a tablet in 1250 BCE shows an improvement in music notation, indicating the names of strings on a lyre. However, the interpretation of the notation system is debatable. In ancient Greece, between the sixth century BCE and the fourth century CE, musical notations were viable examples being the seikilos epitaph. Music notations in the centuries consisted of letter symbols placed above text syllables for the pitches. Long and short symbols represent rhythm in the music. Greece notation fell short of use when the Western Roman Empire declined. Byzantine music has survived as vocal church music characterized by a monophonic chant in byzantine round notation (Troelsgård, 2011). Unlike Greek inscriptions, byzantine neumes had the same modal degree and signature.
The seikilos epitaph is an example of a complete notation musical composition carved in a tombstone in ancient Greece. Pythagoras expanded on the mathematical ratios represented by musical notation of the music scale (Fauvel et al., 2006). He discovered a couple of notes that make an interval of an octave of 2:1. Pythagoras further stated that the ratio of a perfect fourth is 4:3, and that of the fifth is 3: 2 (Martin, 1962). The combination of the ratios led to the development of other notes that made the major scale. The works of ancient Greece inspired Romans, whereby they looked up to them to gain knowledge of classical arts, astronomy, and mathematics. In this essence, Boethius explored the works of ancient Greece for fragments of music notations and expanded on their systems using Latin letters to name the notes of the music scale. He wrote the De Institutione Musica bringing to light Pythagoras's understanding of music and math. He represented the notations with roman letters from A to O, indicating that A is the lowest note a man's voice could sing while the latter is the highest. After a while, Pope Gregory started the first music school in Europe, the Schola Cantorum. He is the father of the Gregorian chant.
St. Isidore discovered a new method of writing music notations using neumes. Isidore used neume notation to add symbols to the music represented by dots and squiggles written above the letters of music lyrics (Strayer, 2013). The neumes notation had its share of a downside because the players of the inscriptions needed to learn when to incorporate higher or lower pitch. The problem was solved by an Italian theorist when solfege was invented, which is commonly known as do, re, mi, fa, so, la, ti, do. He also created a system of four-lined stave notations and organized pitches into hexachords. Guido d'Arezzo, a Benedictine monk, developed the idea of drawing a line on a page and placing neumes with fixed pitch notations (van Waesberghe, 1951). Guido uses a singular red line labeled with one note and then neumes where he wrote above or below it to show relative pitch, whereby the note at the beginning of the line was known as the clef. By the 12th century, musical manuscripts used a five-line stave, and the key signature consisted of just one flat.
Mensural notation was invented in 1300AD, whereby composers made a musical note representing pitch and rhythm for plainchants that were becoming complicated (Deakin, 1892). Mensurations allowed for four essential time signatures and four symbols representing them. In cases where a line had cut through a character, the player had to play the symbol in halftone. The four signatures include the maxima with the most extended duration, breve, longa, and semibreve. Bar lines came into existence in the 17th century, whereby, by this time, notes had taken their oval shape, and eighth, crotchet, and quarter notes were viable. Composers abandoned the old system of menstrual notation and adopted the contemporary fraction style time signature. In the 17th century, Baroque music was evolving into classical music, and improvements had to be made to the notations to keep up with the trend (Bukofzer, 1939).
In contrast to the Baroque period, music notations incorporated slurs, staccato, and characters such as p and f. The composers also reduced the number of clefs to three or four bass, alto, treble, and tenor. On the other hand, music notations have continued to evolve as music evolves (Nowakowski et al., 2021). New musical notation ideas in the contemporary world include aleatoric music and microtones. Others are new inventions like pianos with a hammer between the strings.
Basso Continuo Notations in the Baroque Period
Artists wrote the vast majority of the 16th and 18th-century music in a shorthand called Basso continuo. It is one of the vital aspects of the Baroque period, also known as the continuous bass or throughout the base. In this regard, basso continuo, as the name suggests, is a baseline that exists continuously throughout the lyrics of the music. In the musical notation, only the bass line and melody are written out. On the other hand, figured bass consists of accidentals and numbers below the bass line (ROGERS, 1986). Its purpose is to complement the accompaniment of the harmony between the accompaniment and the rhythm. The accompaniment is then played by stringed keyboards such as the theorbo, arch-lute, harpsichord, or theorbo together with a bass instrument such as the Viola da Gamba. In this essence, composers incorporated bass instruments to accompany chordal tools, such as the harpsichord, to strengthen and reinforce the bass line.
In the basso continuo system of musical notation in the Baroque era, only the bass line notations of the accompaniment are written out (Mattax, 1985). The composers occasionally supplemented the bass line with figures to help the accompanist complete the rest of the complement. In this case, basso continuo incorporating figures is called figured bass. Numbers indicate intervals above the bass note, whereby the notation symbols # and b indicate minor and major cords, respectively. If there are no figures in basso continuo, the assu...
