Improvisation, also known as extemporisation, is defined in music as the spontaneous
invention, composition, embellishment or performance of music. It comes from the Latin
word improvisus meaning unforeseen or unexpected. Improvisation is usually done in a
manner stylistically similar to the piece, and yet not bound by conventions of the original
conventions of the music. Not only is this applied to music, but also to other forms of art like
acting, dancing, singing or artworks creation. Improvisation is an integral part of music, and
it has been around for as long as there has been music. When prehistoric man first struck on a
makeshift drum, or blew down a hollowed out bone with holes in it (Hanson), he was playing
based on instinct, without any form of notation or direction to follow. By doing so, he
became one of the first improvisers.
The term “Classical Music” in this essay includes but is not limited to art music composed
during the Baroque, Classical, Romantic era and beyond. This essay examines how different
compositional and notation techniques throughout the classical period led to the gradual
decline of improvisation, and discusses whether Classical Improvisation is a form of lost art
today.

Ex.1 Kyrie of Machault’s Messe de Notre Dame (Abeele).
Plainchants rely on neumatic notation which developed into the notational forms that are in
use today. Gregorian Chants were preserved in plainsong notation, which assures that chants
would be sung the same way everywhere. The earliest substantial information about
improvisation appeared in treatises, instructing the singer how to add another line to a
liturgical chant as it was performed. The ability of improvising a counter melody to
harmonise with the original chant would require technical knowledge about vertical
consonance and dissonance and of melodic intervals available on the diatonic system. The
earlier improvising singers might have relied on melodic memory to recall the chant, and
eventually the chant would be notated so they could anticipate the notes (Collins 99). The
first manuals on improvisation were concerned with foundation of contrapuntal theory and
practice and with the development of staff notation. Notating the melodies would then ensure
the consistency of the chants. Thus, notation was both a result of the striving for uniformity
and a means of perpetuating that uniformity (Grout 38). The ability to improvise counterpoint
over a cantus firmus was observed as the most important kind of unwritten music, and was
incorporated into every musician’s studies during the Middle Ages.

Modes of improvisation practised in Italy during the renaissance were brought over into the
Baroque period; the embellishment of an existing part and the creation of entirely new part(s)
were two principal types of improvisation. Composers would only write out the melody and
the bass, with the bass played on harpsichord, organ or lute and coupled by a sustaining
instrument like the cello or bassoon. Performers had to realise notated figured bass by
improvising from simple chords to passing tones to counterpoint, which completes the
harmony as well as produces a fuller sonority.
Sometimes active melodic lines are varied with consonants with longer note values and their
own melodic shape. The parts may be inverted with the hands shifting roles — a common
practice and a method of composition favoured by Scarlatti and Handel in the opening of
their compositions (Ex. 1).
Ex.1 Scarlatti Sonata in a minor, K.54
The example above is taken from one of Scarlatti’s Keyboard Sonatas, which shows the piece
beginning with a single melodic line played with the right hand. The melody line is then
repeated in bar 3, but played with the left hand and slightly varied at the end, while right hand
harmonises the melody with thirds.

Composers began to exercise control over ornamentation by writing out symbols or
abbreviations in some instances. Although they were indicated by ornamentation symbols,
they still retained certain spontaneity. Many modern musicians view ornaments as merely
decorative, and eventually brought about the term “melodic decoration”. Baroque musicians
believed that ornamentations were means of colouring the notated piece with dissonance
especially with trills and appoggiatura.
Ex.2 Embellished Opening of Corelli’s Violin Sonata Op.5 No.3, with ornamentation notated.
The figure above shows early examples of composers dictating performance of their piece.
Corelli published both the embellished and original parts, which may have influenced later
performers to depend on such performance directions given to them by the composers.
Another form of embellishment commonly found in opera and some of the instrumental
music of Arcangelo Corelli was an elaborated extension of the final cadential chord (Grout, A
History of Western Music, 362). Performers had the liberty to display their virtuosity freely
by adding, subtracting or changing the cadenzas in the written scores. Composers of
variations, suites and sonatas were well aware that selected movements from their
compositions could be excluded at the performer’s discretion.

Ex.3 Cadenza in first movement of Corelli’s Violin Sonatas Op.5 No.3
Bach’s Brandenburg Concerto No.5 in D major, BWV 1050 was also notated with a lengthy
cadenza (Brandenburg Concertos 1-6). This is similar to compositional practices in later
periods when the orchestra stops playing during a portion of the concerto, which allows the
soloist to play alone ad libitum, with a flexible pulse.
From these examples we can see how Baroque composers integrated improvisational
techniques into their compositions. The organ improvisations of Sweelinck, Frescobaldi and
Buxtehude won the admiration of crowd, and Bach is known to have improvised a prelude
and fugue, an organ trio, a chorale prelude and a final fugue all on a single hymn tune
(Collins 111). An organist was scheduled to compete against Bach in improvising, but
promptly left town after hearing him improvise while warming up (Barnhill). The dictation of
their own compositions by adding ornamentation or actual florid notation for their passages
was a practice that became common in the 18th
century. It diminished the trend of leaving
embellishment to the performer. It was generally felt that with less specific notation, the
music served as something of a blueprint, and could be constantly refreshed and kept current
by the idiomatic addition of improvised graces (Collins 107).

During the early 18th
century, a new style of music surfaced to succeed the older Baroque
styles. This new style sounded more songful and less contrapuntal, more natural and less
artificial, and more sentimental and less intensely emotional than its Baroque counterpart
(Hanning 249). During this period, composers started to give explicit directions on dynamics,
phrasing and tempi. They began to notate and dictate exactly how they wanted their
compositions to be played.
Performers and composers of the classical period preserved three types of Baroque
improvisation — embellishment, free fantasies and cadenzas. They were still frequent during
performances, with soloists likely improvising during orchestral ritornellos1 while performing
keyboard concertos.
Ornament directions began to appear soon after the beginning of the 18th
century. This was
the beginning of precise notation and performance of ornaments, which limits the performer’s
freedom. The standardisation of ornamentation signs and symbols was developed, as there
was no standard system yet. Composers also notated embellishments for the benefit of
amateurs or students who have not mastered the art of improvisation. This, to a certain extent
created a form of dependency on the composer’s absolute directions (Bach 203).

Ex.4 Mozart Piano Sonata in F major, K332/330K, 2nd
movement
From Ex.4 we can see the differences between Mozart’s autograph edition and the published
first edition. By the 1790s composers were writing elaborate embellishments into thematic
reprises, having expropriated embellishments from the domain of improvisation (Collins 113).
Early dictations for cadenzas could be traced back to the late 16th
century, where Caccini
wrote a cadenza in Io che dal ciel cader (the fourth intermedio for Lapellegrina). Composers
were in a sense paranoid about their compositions being spoilt by eager performers of
questionable compositional talents. They thus included ornamented cadences, or condensed
embellishments at the end of the piece. Cadenzas occupy the penultimate position in the
musical structure (Sadie 785), where they precede the final tutti of the concerto movement or
aria, and are always indicated by a fermata over a 6-4 Chord followed by a perfect cadence.
Beethoven wrote out a complete cadenza for his Piano Concerto No.5 in E-flat Major, Op.73,
and some composers have followed suit. However sometimes it is still up to the performer’s
discretion to ignore the notated cadenzas and give their personal renditions (Barber 110).

Mozart and Beethoven were celebrated improvisers, with their solo concerts featuring solo
improvisation. To a great extent, the improvisations were metrical, giving the impression that
they were composed in advance. Beethoven’s Fantasia in G minor, Op. 77 (might have been a
revision of an improvisation at his Akademie at the Theater an der Wien) did contain several
ametrical passages. Walthur Dürr suggested that improvisations on Schubert’s songs would
be frequent due to the lack of piano introductions. Competitions were held during this period
by aristocratic families and nobles, where composers and performers were invited to compete
against each other. Mozart competed at least once in improvisation with Muzio Clementi
(Albert 624), and Beethoven won many improvisatory battles over contemporaries like
Hummel, Steibelt and Woelfl (Solomon 78).
A substantial rise in the popularity of improvisation was seen in the early 19th
century, which
then declined to near-extinction in 1840 after suffering an ‘apotheosis of bad taste’
(Wangermée, 1950). Improvisation progressively became mundane by pandering to a music-
consuming middle class that craved brilliance and sensation. Artistic originality which
distinguished improvisation during its 18th
century heyday became insignificant, encouraging
its rapid decline. Other factors that led to extirpation of public improvisation included the
rising importance of the performer as the interpreter of the composition, the separation of
composition from performance. The evolution of musical technique away from bass-
orientated, systematic structural outlines towards a more melodically, generically or
programmatically held frameworks, thus loosening the threads that held extemporised music
together.

Ex. 5 Example of notated embellishment which is greatly improvisatory from Chopin’s
Nocturne in D-flat Major, Op. 27 No.2
Cadenzas and embellishments lost their improvisatory characteristics as they were notated by
the composers in concertos, while improvised embellishments were scorned by Liszt as
‘sacrilegious violations of the spirit and letter’ of composed music. Following in the steps of
Beethoven’s 5th
Piano Concerto, pianist-composers usually notated cadenzas into their
compositions or transcriptions. Liszt rarely left the performer to improvise on a fermata sign,
and he supplied all improvisation materials himself. Even in his transcriptions of operatic
arias by Rossini and Bellini, Liszt wrote out cadenzas at points where fermatas indicate their
insertion (Sadie 789).
Beethoven’s music in the 18th
century was absolute: he indicated his intentions in notation,
dynamics, phrasing and even explanatory remarks. Romantic composers conformed, and later
into the 19th
century even the preference for certain individual strings, fingerings, number of
players, and seating arrangements were indicated in great detail. Composers aimed to make
their scores as self-explanatory and as safe from modification as possible; printed scores were
revised for the masses to become more explicit, inhibiting the performer’s creative freedom.
Brahms once said that the so-called instructive or practical editions are seldom concerned
with art.

Improvisatory styles and procedures were incorporated into composers’ formal compositions
also influenced the decline of improvisation, as the emancipation and ‘stretched conventions’
grew into compositional practices, adversely affecting its distinction from composition.
Improvisation however, did not disappear altogether but became restricted to domains like
organ playing, often in the ‘strict fugal’ style described by Czerny and contemporaries
(Collins 121). 19th
century improvisation was still practiced, with Bruckner captivating
audiences with remarkable improvisation on the organ, Chopin and Liszt improvising
publicly on two pianos.
The early 20th
century added extempore piano accompaniment to silent films, and of course
the most prominent of new improvised music was jazz. The latter half of the 20th
century saw
passionate debates about issues as to whether trills ought to start with the upper note, or
whether grace notes should be played before or on the principal beat. A new form of classical
music also placed certain importance on improvisation, by using ambiguous notation, and
rules instead of scores, placing fewer restrictions on the performer. In the 1950’s a new type
of improvisation was created with the birth of aleatory music. Charles Ives had earlier
exhorted performers of his music to improvise and often wrote unrealizable notations which
tacitly forced the performer to create his own music (Kirshnit).
With the dawn of electronic music, new-age composers tried to exercise near-total control
over performance by including a plethora of detailed indications for dynamics, manner of
attack and tempo. Composers who did not follow the common practices like John Cage and
Harry Partch which requires both the composer performer to improvise might have
contributed to the restoration of improvisation, albeit different from before — other factors
includes the growth of live electronic music, the evolution of jazz to a point where it
Chua Tung Khng 11
enveloped everything in the contemporary classical tradition and the emergence of aleatory
music. Improvisation was soon acknowledged as second to composition.
In a sense, the idea of classical improvisation that has been in practice until the late 19th
century has taken a whole new direction, in accordance to the compositional styles and
harmonic language that has evolved from the medieval modes to aleatoric or atonal music.
‘Contemporary classical music’ generally deals with the deconstruction of everything that has
been done before, in the name of creating something that is thoroughly ‘new’ (Harris). In
recent musical cultures, without the elements of common practice on which improvisation
depends, the idea of extemporising cadenzas to an atonal piece (e.g. Schoenberg’s Violin
Concerto) would be senseless.
The birth of the music business, the dwarfing of classical music by popular music and the
obsession of creating the ‘perfect recording’ might have led to the penultimate chapter of
classical music. Music education is provided in public school curriculum, but it has been
rendered almost worthless by a politically correct tendency to treat all music as equal — the
primitive and the refined, the commercial with the spiritual (Lebrecht xiv).
From ‘When the Music Stops’ by Norman Lebrecht:
For this state of impotence, music had only itself to blame. An art that once paid its
own way had, through ambition and greed, fallen upon the charity of politicians and
businessmen. This dependency culture, created by the avarice of millionaire
conductors, singers and their agents, reached a point where it was no longer
sustainable by public and corporate funds. In the final years of the twentieth century,
orchestras and opera houses that upheld the traditions of Bach and Beethoven were
facing a daily threat of foreclosure.

Composers were among the most famous improvisers of their time. Great composers we
know today earned their reputation first as an improviser, then a composer. From the 19th
century, composers dictated over previously improvised elements of their compositions,
which clouded the distinction between composition and improvisation even further. With the
focus of creativity and originality demands slowly shifting towards technical perfection and
the technical revolution of 20th
century which encouraged musicians to record and perfect
their performances, classical improvisation gradually dwindled in the Classical realm.
Compared to improvisation in non-Western and native music, improvisation plays a small
role in Western art music. Today, classical artists who put spontaneity in their art are rare, as
are those who give improvisatory performances as part of their concert.
