INTRODUCTION

Overview

In the past few years, I have become very interested in Bela Bartok's

music and I have studied some of his scores. Among his chamber works,

Music for Strings, Percussion and Celesta is one of my favorites. As a

nationalistic composer, Bartok is famous for the use of folk materials in his

music, and this piece is no exception. Bartok's music has become a model

for my various compositions. My composition entitled Piano Quintet is my

homage to Bartok.

The instrumentation of my piano quintet is an intentional reference to

Bartok's Music for Strings, Percussion and Celesta. In my piano quintet, I

try to achieve a similar sound without using the same instrumentation.

Instead, I use the string quartet to represent the string part and the piano to

represent the percussion and the celesta parts. My piano writing is

predominantly percussive; heavy chords and dissonant intervals are

frequently used, especially in the lower register. As the piano is a

percussive instrument in nature, it can easily imitate the sound of a drum.

On the other hand, the strings do a better job for performing the legato

melodic lines. I have limited the use of special effects on the string parts so

that in the future, they can be played by wind instruments without needing

major revision.

In this piece, I try to incorporate Bartok's compositional techniques

while utilizing my own melodies and other compositional devices. Like

Bartok's music, my piano quintet incorporates folk material, thematic

transformations and the use of the golden ratio to determine the formal

structure. Yet, my compositional technique differs from Bartok's as a

result of my approach to harmonization, counterpart writing, fugal writing

and tonal planning.

Stylistic features

The first movement is toccata-like and uses short, detached,

syncopated rhythms. The movement is fast and should be played in a strict,

steady tempo. The piece is written using sonata allegro form and each

section can be clearly heard. The length of this movement is about 5

minutes.

The second movement is much more relaxed and the rhythm flows

freely. The first section is a fugue for string quartet only. The piano plays

only in the second section. There is also a theme in this movement which

resembles Bartok's folk tune. The length of this movement is about 4

minutes.

The third movement is an energetic dance movement. It contains

more metric changes than the other two movements and utilizes a large

variety of rhythms. This movement is also played in various tempos with

two andante sections embedded within this fast movement. All the themes

of the entire piece appear in the middle of this movement. This utilization

of thematic material is similar to the opening of the Finale of Beethoven's

symphony no.9. The length of this movement is about 4 minutes and 30

seconds.

In general, the texture of this piece is contrapuntal. Linear motion is

more important than the succession of vertical sonorities. Although

harmony is at times the incidental result of this contrapuntal motion, the

formation of vertical sound was carefully planned. When I composed this

piece, I tried to adjust the vertical alignments of each of the voices with

priority given to the intervals in the table 1:

1st A4 d5

2nd P4 P5

3rd M2 ml

4th m2 Ml

5th M3 m6

6th m3 M6

7th unison 8ve

The selection of intervals was the most important factor in

constructing melodies and their variations. Besides interval, rhythm is

another essential element since the change of rhythm can completely alter

the appearance of a melody without changing the intervallic relationship.

All of the themes are motivically related to each other. In some

places, these themes play simultaneously or follow each other in order to

create a sense of organic unity. For example, in the first movement, there

are two themes in the exposition and one theme in the development. All of

these themes reappear in the recapitulation.

The harmonic language employed in this work is an eclectic mixture

of both tonal and atonal sonorities. Different scales have been used in this

piece, they include: diatonic, chromatic, church modes, Messiaenic modes

and the octatonic scale, which was Bartok's favorite. The work starts and

ends with the note F, the pitch that serves as the tonal center for all three

movements of the composition.

FIRST MOVEMENT

The first movement is in sonata form, having sectional

division determined by golden ratio (golden section or golden means).

Many composers have use the golden ratio to compose their works;

among them, Debussy and Bartok are the most famous. The Golden ratio

is the division of a fixed length (A+B) into two segments so that the ratio

between the longer (A) and the shorter (B) segments equals the ratio of the

longer portion to the entire length, l (See Fig.l)

Figure 1 — Golden ratio

A B

II I II

(0.618) (0.382)

1. From Howat, Roy. Debussy in proportion, pg. 1 -4 . Cambridge: Cambridge University press. 1983.

In mathematical calculations:

A > B; B = A A A+B

The irrational value of the golden ratio (0.618034) is also

implied in the "Fibonacci" series. A characteristic feature of this series is

that every number is equal to the sum of the sum of the two preceding

numbers:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, etc.

As the series extends to higher values, it more accurately

approximates the irrational key-number of the golden ratio. For instance,

the golden ratio of 34 is 21, and that of 55 is 34. See at figure 2.

Figure 2 ~ Calculation of the golden ratio of 34 and 55

34 x 0.618034 = 21.013156

55 x 0.618034 = 33.99187

Bela Bartok is one of the composers that has used the golden ratio to

determine the structure of his music. An example is found in the first

movement of the Music for Strings, Percussion and Celesta, perhaps the

most often cited example using this proportional ratio.2

Figure 3 shows the sectional division of the first movement of

the Music for Strings, Percussion and Celesta, which consists of 89

measures and is divided into two sections of 55 and 34 measures each. It

starts at a pianississimo dynamic level, gradually rises to fortississimo at

mm.56, and recedes to pianississimo at mm.89. The section leading up to

the climax (m. 55) shows a division of 34+21 measures, and the section

following the climax is divided into 13+21 measures.

In the first movement of my Piano Quintet, the relative length of the

three sections is determined by the golden ratio. However, the fibonacci

series was not used. Instead, the golden mean division is calculated using

the durational value of each section (0.618 and 0.382 respectively). This

calculation is based on the cumulation of eighth notes. In the figure 4

below, there is a clear calculation of the proportional ratio of the first

movement of the Piano Quintet.

The number of eighth notes in the first section: (50x3) + (103x2) + (6x3) = 374

The number of eighth notes in the second section: 76x3 = 228

The first movement consists of a total of 235 measures. The

first large section is found in mm. 1-159 and includes the exposition and

development, the recapitulation lies within the second section. Table 2

of the first movement:

Piano

The movement opens with a short introduction in which the

piano plays an underlying low register F pedal point (see ex.1). The main

theme enters at m.3 in the piano and then again in m.16 in the strings (see

ex.2). The exposition lasts until m.68, where a second theme (see ex.4)

enters at m.51 in 2/4 meter, and leads to the development.

The main theme (see ex.3) of the first movement contains five notes

derived from the whole-tone scale, in which the interval between each note

is a major second:

development

This section is the longest in the entire movement, there is new

third theme which is motivically derived from the main theme. This theme

consists of a compound line in which one part moves around a repeated A.

(see ex. 5). The interval between each note in the upper part is a second,

which is a variation of the first theme. However, this is based on an aeolian

scale rather than the whole-tone scale.

lower part

The development section is more contrapuntal and incorporates

dialogues and canonic passages throughout. This section develops material

based upon the second and the third themes. The music moves toward a

violin cadenza in m.91 which I call a " false climax." This is a term used to

describe a climatic section that sound as though it should have led into the

recapitulation; however, the music continues to develop further after this

climatic moment. From m.lOl, the music starts to build up again toward

the true climax in mm. 154-159. At this climatic moment, all of the

instruments play a unison, fortissimo passage. The meter changes from 2/4

to 3/4 and connects smoothly into the recapitulation section.

recapitulation

The recapitulation is in 3/4, which implies a hemiola effect to the 6/8

meter of the exposition section. The recapitulation starts with the piano in

the second beat of m.159, announcing the introductory pedal point of the

movement. However, instead of resounding an F, the pedal point states an

A that acts as a leading tone and moves to Bt». From m.162, the pedal point

in the piano reminds us of the exposition. The theme in the first violin part

in mm. 187-188 is the third theme. This is the first recognizable theme

from the previous sections.

There are functional harmonic passages in the recapitulation

section. The Eb section at mm. 182 exhibits a subdominant relationship to

the Bb section. However, the activities are not too busy compared to the

previous sections. The texture of this section thins after the reappearance of

the main theme at mm. 204. The whole movement ends with two

successive dyads on the piano.

SECOND MOVEMENT

This movement is in a slower tempo than the first movement.

It is divided into two parts as follows:

section 1: mm. 1-53

section 2: mm. 54-end.

I tried to imitate Bartok's folk material in this movement. Most folk

tunes are short, canatabile and in a simple rhythm. For example, in

Bartok's Mikrokosmos no. 128 (peasant dance), Bartok uses a short melody

to represent the spirit of the peasant (see ex.6)

Example 6. Bartok's Mikrokosmos no. 128, mm.5-6.

My melody (see ex.7) is an imitation of Bartok's folk tunes in the

example 6. I tried to write a short melody which shares the characteristics

of the folk tune in example 6. My melody is relatively short, rhythmically

simple, and is derived from a scale that is similar to the octatonic scale.

Example 7 — Violin II part, mvt.II, mm. 58-59

#1 #2

P 4- *

This tune is written from a scale which I deduced from the octatonic scale:

Figure 5 — Octatonic scale

I ,

— M J f 1

With F and B omitted, the note series will become:

Figure 6 ~ My scale

I , i • ' $ J J r m

This scale pattern doubles the range of the possible transposition of

the octatonic scale, allowing six transpositions, as shown in the table 3:

Table 3 Transpositions of the scale

1 C D D# F# G# A

2 C# D# E G A A#

3 D E F G# A# B

4 D# F F# A B C

5 E F# G A# C C#

6 F G G# B C# D

The whole movement is pastorale in nature. The first 15 measures

are a dialogue between the two violins, in 5/8 meter. From m.16, a fugal

section starts in 6/8. The two violins continue their dialogue, in m.23 the

viola enters as does the cello in m.25. The whole first section is played by

the strings without the piano. The piano enters in mm.54, which is the

beginning of the second section.

The second section of this movement provides a complete

contrast to the first section. This is an Allegretto in 4/8 meter and includes

the addition of the folk-tune theme. By using a faster tempo, the music

becomes more lively and dance-like. The dance keeps going with the theme

weaving among the lines. The whole movement ends on F in mm.85.

THIRD MOVEMENT

One of Bartok's compositional techniques is the use of an arch as a

structural determinant. The arch can be used to determine the formal

structure, metric organization, motivic design and other aspects of a

composition. For example, the selection of meters in Bartok's

Mikrokosmos no. 100 is clearly an arch form.(see table.4)

I _ L L I

In my piano quintet, the third movement is divided into three sections:

section 1: mm. 1-59 section 2: mm.60-79 section 3: mm.80-73

This movement is composed in an arch form. The structure is

determined by using a method similar to that used by Bartok. I tried to

pre-select the meters before writing the notes. There are always central

meters that function as the axis of the symmetry. As table 5 shows, the 6/8

meter in m.4 (with an asterik indicated below the meter) acts as the axis of

symmetry for mm. 1-5. There are also axes between two arches; for

example, the 8/8 meter in m.8 is the axis for m.1-15. I used the arsch

form in the first (mm. 1-59, table 5) and the third sections (mm.80-173,

table 6). Both sections contain a total of 23 metric changes.

Section I

This movement starts with the low running bass line play on the

piano, in 7/8 meter. The main theme of this movement is an arch like

melody, as seen in ex.8. Here, the fundamental structure consists of an F -

Gb - F. In this respect, Gb functions as the axis in a small arching motive.

In addition to utilizing this new theme, the themes from the first and

second movements also reappear in the opening section of the third

movement. In m.l 1 (see ex.9), the piano plays a theme derived from the

first theme of the movement. Later in m. 27 (see ex.10), the folk material

derived from the second movement appears.

Section 2

The tempo of the second section is Andante con moto. There are

only four meter changes in this section (see table 6). The slow tempo,

with the relaxing atmosphere and the cantabile melody, is similar to the

first section of the second movement. After six measures, the music

gradually develops into a fugal passage in m.66. In mm.71-75, the texture

becomes more intense and the tempo accelerates, providing a transition to

the last section.

Section 3

This section is the conclusion of my Piano Quintet. As a

culmination of the entire work, it includes a lot of material used in the

previous movement and the previous sections of this movement. The

figuration in the cello part at mm.80-81 (see ex.l 1) is reminiscent of the

opening of this movement. As seen in example 11, the cello part at

mm.94-95 (see ex.12) is derived from the first theme of the first

movement. The first violin part at mm.122-123 (see ex.13) is derived

from the third theme of the first movement. In mm. 144-145 (see ex.14)

the strings play the theme from the exposition of the first movment.

Unlike the other movements, the music becomes more intense toward the

end. The whole piece ends with two scales in contrary motion that each

end on F, the tonal center of the piece.

CONCLUSION

In the end, I am glad that I have composed a work using a variety of

techniques that provide the trademark of Bela Bartok, my favorite

composer. Although it is not stylistically fashionable in the 1990's, this

homage is my first personal achievement to be able to apply another

composer's techniques within my own music. I hope to develop my own

personal style through this experience in the future.
