CLASSIFICATION OF MUSICAL  INSTRUMENTS

Aside from the voice ,musical sound is produced by musical instruments. These instruments come in different sizes and shapes. Usually, they are made from raw materials available in the locality.
Indigenous people, for example, make use of wood, bamboo, animal, skin, gourd, coconut shell to create their own  set of musical instruments. Other musical communities or groups use steel, metal, nylon strings, brass, and plastic to create musical instruments that suit their way of living and their culture .it is
Important to note that though instruments  vary in the quality of material they are made [of, they all serve  the purpose  of providing cultural band self-expressions as well as musical entertainment .

Musical instruments are classified according to how their respective sounds are produced by the instrumentalist or performer. This system pf musical classification is called the sachs-Hornbostel system.

*    Idiophones
Are instruments that are struck,shaken or rubbed. Bells, cymbals, triangles, and maracas are examples of this group of musical instruments.
                                                                 EXAMPLES






*    Membranophones

Ø  Are musical instruments that use stretched skins as membranes. They are struck with bare hands or with the use of sticks or mallets .some examples of this kind of instrument include the timpani, bongos, tugo, dabakan, and snare drums.



EXAMPLES:
SNARE DRUMS
DABAKAN





TUGO

*      Aerophones

Ø  Are wind instruments that Are blown on the mouth –piece to produce sound.trumpets,horns,saxophones
                   sahunay, and flute belong to this group of instruments .in the case of the nose flutes,sound is                          produced by exhaling air through the nostrils

FRENCH HORN
SAHUNAY
EXAMPLES:
NOSE FLUTE




*    Chordophones

Ø  Are string instruments that are either  plucked or bowed. Examples of this kind of instruments are the  kudyapi, banduria, laud, violin and lutes.

                                    EXAMPLES:

LAUD

VIOLIN
KUDYAPI

*    Electrophones
Ø  Are instruments that use electronics group includes the keyboard, electric guitar, and electronic drums.

EXAMPLES:
KEY BOARD
ELECTRONIC DRUMS

*      Instrumental music  is divided into two broad categories known as chamber  music and orchestral musics.



*    Chamber music
Ø  Is a composition played by a group of musicians for a small room  performance .the smallest group  that can perform  chamber  music is called a duo(two musicians).other groups may perform music in trio(three musicians),quartet(four musicians),quintet(five musicians), octet(eight musicians), and so on. The most popular instrumental combination  for chamber  music is the string  quartet.other chamber music  may performed  by the brass quintet which is usually made up of two  trumpets ,French horn, A trombone, and a tuba.
* Orchestral music and instruments
Ø  The term orchestration in its specific sense refers to the way instruments are used to portray any musical aspect such as melody or harmony.
For example, a C major chord is made up of the notes CE, and G. If the notes are held out the entire duration of a measure, the composer or orchestrator will have to decide what instrument(s) play this chord and in what register. Some instruments, including woodwinds and brass are primarily monophonic and can only play one note of the chord at a time. However in a full orchestra there is generally more than one of these instruments, so the composer may choose to outline the chord in its basic form with clarinets or trumpets. Other instruments, including the strings,pianoharp, and pitched percussion are polyphonic and may play more than one note at a time.
Additionally in orchestration, notes may be placed into another register (such as transposed down two octaves for the basses), doubled (both in the same and different octaves), and altered with various levels of dynamics. The choice of instruments, registers, and dynamics affect the overall tone color. If the C major chord was orchestrated for the trumpets and trombones playing fortissimoin their upper registers, it would sound very bright; But  if the same chord was orchestrated for the celli and string basses playing sul tasto, doubled by the bassoons and bass clarinet, it might sound heavy and dark.
*    There are four basically  four sections in the orchestra.


1. stringed instruments (chordophones)
Ø  are often referred to as the “backbone” of the orchestra.

 EXAMPLES:



·         The violin  is the leader and the heart  of the instruments  in the orchestra.it is played  by moving the bow across the strings.sometimes the strings are also plucked with fingers.
·         The viola looks like a violin but is a little larger, it is tuned fifth lower than a violin.
·         The cello is held between the knees as the player  moves the bow to and fro .it is larger than the viola.
·         The double bass is the largest  among the stringed instruments but has the lowest pitch.


2. Woodwind instruments (aerophones)
Ø  Are blown through the mouth piece .the air passes     through the air column and it impinges  on an edge or on a reed.

EXAMPLES:


 ·              The piccolo is the smallest instrument in the wood wind section .it has a range of an octave higher than a flute.
  ·                 The flute has high range and is extremely capable of producing rapid successions of tones.
               The oboe is the most expressive among the woodwind musical instruments.
    ·                  The clarinet is a cylindrical instrument with a cup- shaped mouth piece and a flaring bell at the end.
·               The bassoon is called the “clown” of the orchestra with a long curving metallic mouthpiece.its tone is soft and mellow.

3.Brass instruments

Ø  Are also aerophones but are made out of brass metal.
·        The trumpet is the main instrument of the brass section and makes a brilliant and brassy sound.
· The trombone is the only sliding instrument in the brass section that shifts pitch in any key.
· The French horn is a coiled brass instrument that is more mellow than the trumpet.
·       The tuba is the largest instrument in the brass section;it has the lowest pitch.

EXAMPLES:



4.percussion instruments


Are considered the special effects department  of the orchestra  because of the dynamics rhythmic effects they ·         the tambourine,the triangle,the snare drum and the bass drum.
Ø  create.most percussion  instruments are played by striking  the instruments with sticks  and mallets .other are  sounded by shaking  or rubbing .
Ø      These instruments are further  classified into two groups,namely the definite pitch percussion and the indefinite pitch percussion instruments
Ø  Examples of percussions  instruments with definite   and indefinite pitch are the following:
·         The  xylophone  consists of a set  of wooden bars arranged  in scale .it is struck with a set sticks .
·         Chimes a set of metal tubes hanging from a frame. Its metal tubes are struck  to create the  musical sounds.
·         The timpani or kettle drums  are bowls made out  of copper  or brass that are covered  by a stretched membrane.
