Concepts of music
Concepts of music are an important tool that helps in analyzing music and give in detail the various attributes it possesses. They also act as an ingredient and offer guidance to people or students who would like to pursue music as a career. This paper helps to describe this concepts:
Duration is an important music concept, and it refers to the length of a note. Duration is one of the various properties of a tone which forms the basis of a rhythm in a song. Duration can be described as either long or short. The duration of music has various aspects. The first aspect of duration is the beat. A beat is the regular pulse in a particular piece of music, and it causes people to tap whenever music is playing. A beat can be described as strong, weak, definite or indefinite. The other concept of duration is the metre. In the music, metre is described as a group of beats that are heard as an organized succession of rhythmic pulses. Also, tempo is used to describe the duration of music. It refers to change in speed and how it affects the music.
The second music concept is pitch. Pitch enables the proper ordering of sounds on a frequency scale. It can be described as either higher or lower in relation to musical melodies. The pitch is described based on the frequency of a particular vibration. Though pitch and frequency are similar, frequency is objective while pitch tends to be subjective. The pitch of a sound is measured as a frequency and is quantified in terms of cycles per second. Therefore, pitch is measured according to the vibrations it causes on a sound wave. The pitch of a sound is affected by pressure. The pitch of a sound increases with low pressure and decreases with high pressure.
Dynamic and expressive techniques
The other music concept is the dynamic and expressive techniques. In the music, dynamics describes the volume of the sound. The volume of sound increases with an increase in the amplitude of a particular sound wave. The highest volume is called a peak while the lowest volume is called a trough. The change in sound dynamics is what keeps the listeners interested and engaged emotionally. Various words like piano, crescendo, forte and diminuendo among others are used in describing the volume of sound. On the other hand, expressive techniques refer to how a performer uses various techniques and effects to express personal interpretation of the music. These expressions depend on the source of the sound and instruments. Accent is one type of expressive techniques and it involves emphasizing a note dynamically thus making it stronger. The other types include Glissando, Legato and Staccato among others.
Color is another music concept. It refers to the quality of sound and its sources. The tone color depends on the instrument from which the sound originates. The sound sources are of various categories. These include orchestral which include brass, percussion and string. The other source category is electronic sources which may either be loop based, synthesized or a replication of acoustic. The sound color is affected by the surrounding environment. A good example is the sound produced in a hall where it is affected by the echo produced.
The other type of music concept is the texture. Texture in music refers to the layers of sounds or it can also describe the combination of tone colors in music. The texture of music can be described as either thick or thin. Thin sound texture is experienced when there exists some few sounds having a high pitch or having linear ideas. It occurs when many instruments are playing a particular melody together. The texture of sound becomes thick when the spectrum and activity of sound increases. This implies that the kind of music that uses many instruments and includes a layer of melodic and harmonic lines has a thick texture. Sound texture has various practices like doubling, unison playing, different instruments imitating melodic ideas and the use of question – answer phrases. Additionally, texture is divided into various categories. One category is the monophonic category which refers to a kind of music which has a single melody being played. The other category is the Homophonic texture which contains a harmonic that is supported by harmonic accompaniment. Polyphonic texture mostly exists in music when more than one melody is predominant. Lastly, Heterophonic texture occurs when many instruments play embellishments the same tune.
The last concept of music is the structure. The structure is used to describe the form of the music. It helps to show how various musical shapes are combined together to form a complete work. It also facilitates in identification of various changes and repetitions of musical ideas . These ideas are then grouped to form distinct sections. The sections allow the grouping of musical events into discernable parts. New sections are identified by the emergence of new ideas as each new idea highlights a new section. The music texture is grouped into various forms. The first form of texture is the blues form. The Blues form uses a repetitive A section and its changes revolve around other musical concepts. The popular song form comprises of a combination that is selected from the intro, instrumental, verse, chorus and Outro sections. On top of this, the Binary form comprises of an A section and a B section following each other. Other forms include Rondo and Through Composed.
The music concepts help to explain the pillars that form the music. They help a person to understand music in depth and appreciate it both as a career and as an art.
