birdsong

Certain vocalizations of birds, characteristic of males during the breeding season, for the attraction of a mate and for territorial defense. Birdsong also reinforces pair bonds, and some species have a flight song. Birdsongs are usually more complex and longer than birdcalls, which are used for communication within a species. Birdsong may be hereditary or learned; a newly hatched male chaffinch, for example, can sing a “subsong” but must learn to sing the true song by listening to and imitating adult males.

U.S. a cappella singing style incorporating many folk hymns and utilizing a special musical notation. The seven-note scale used by some singers is sung not to the syllables do-re-mi-fa-sol-la-ti but to a four-syllable system brought to America by early English colonists: fa-sol-la-fa-sol-la-mi. The system reflects the fact that a series of three intervals repeats itself in the major scale. A differently shaped note head is used for each of the four syllables. The singer reads the music by following the shapes; singers unfamiliar with the system can read the notes according to their placement on the staff. The tradition started in New England and moved South and West as more sophisticated forms of music reached the U.S. Shape-note singing had largely died out except in rural areas by the 1880s, but it has experienced a revival in recent years. The traditional shape-note hymnal, The Sacred Harp, first published in 1844, remains in use today.

Popular vocal ensemble consisting of four unaccompanied male voices. The voice parts are tenor, lead, baritone, and bass, with the lead normally singing the melody and the tenor harmonizing above. The emphasis is on close harmony, synchronization of word sounds, and variation of tempo, volume, diction, and phrasing. Barbershop apparently originated in the U.S. in the late 19th century, when American barbershops formed social and musical centres for neighbourhood men, though the term may derive from “barber's music,” the British term for an extemporized performance by patrons waiting to be shaved and referring to a barber's traditional role as a musician.

Singing is the act of producing musical sounds with the voice, which is often contrasted with speech. A person who is singing is called a singer or vocalist. Singers perform music known as songs that can either be sung a cappella (without accompaniment) or accompanied by musicians and instruments. Singing is often done in a group, such as a choir. Nearly anyone who can speak can sing, since in many respects singing is merely a form of sustained speech. It can be informal and just for pleasure, for example, singing in the shower or karaoke; or it can be very formal, such as singing done professionally as a performance or in a recording studio. Singing at a high amateur or professional level usually requires a certain amount of innate talent and a great deal of regular practice, and/or instruction. Professional singers usually build their careers around one specific musical genre and undergo voice training, provided by a voice teacher or coach throughout a career.

The human voice and singing

In its physical aspect, singing has a well-defined technique that depends on the use of the lungs, which act as an air supply, or bellows; on the larynx, which acts as a reed or vibrator; on the chest and head cavities, which have the function of an amplifier, as the tube in a wind instrument; and on the tongue, which together with the palate, teeth, and lips articulate and impose consonants and vowels on the amplified sound. Though these four mechanisms function independently, they are nevertheless coordinated in the establishment of a vocal technique and are made to interact upon one another. During passive breathing, air is inhaled with the diaphragm while exhalation occurs without any effort. Exhalation may be aided by the abdominal, internal intercostal and lower pelvic muscles. Inhalation is aided by use of external intercostals, scalenes and sternocleidomastoid muscles. The pitch is altered with the vocal cords. With the lips closed, this is called humming.

The sound of each individual's singing voice is entirely unique not only because of the actual shape and size of an individual's vocal cords but also due to the size and shape of the rest of that person's body. Humans have vocal folds which can loosen, tighten, or change their thickness, and over which breath can be transferred at varying pressures. The shape of the chest and neck, the position of the tongue, and the tightness of otherwise unrelated muscles can be altered. Any one of these actions results in a change in pitch, volume, timbre, or tone of the sound produced. Sound also resonates within different parts of the body, and an individual's size and bone structure can affect the sound produced by an individual.

Singers can also learn to project sound in certain ways so that it resonates better within their vocal tract. This is known as vocal resonation. Another major influence on vocal sound and production is the function of the larynx which people can manipulate in different ways to produce different sounds. These different kinds of laryngeal function are described as different kinds of vocal registers. The primary method for singers to accomplish this is through the use of the Singer's Formant; which has been shown to match particularly well to the most sensitive part of the ear's frequency range.

Vocal registration

Vocal registration refers to the system of vocal registers within the human voice. A register in the human voice is a particular series of tones, produced in the same vibratory pattern of the vocal folds, and possessing the same quality. Registers originate in laryngeal function. They occur because the vocal folds are capable of producing several different vibratory patterns. Each of these vibratory patterns appears within a particular range of pitches and produces certain characteristic sounds. The term register can be somewhat confusing as it encompasses several aspects of the human voice. The term register can be used to refer to any of the following:

• A particular part of the vocal range such as the upper, middle, or lower registers.
• A resonance area such as chest voice or head voice.
• A phonatory process
• A certain vocal timbre
• A region of the voice which is defined or delimited by vocal breaks.
• A subset of a language used for a particular purpose or in a particular social setting.

In linguistics, a register language is a language which combines tone and vowel phonation into a single phonological system.

Within speech pathology the term vocal register has three constituent elements: a certain vibratory pattern of the vocal folds, a certain series of pitches, and a certain type of sound. Speech pathologists identify four vocal registers based on the physiology of laryngeal function: the vocal fry register, the modal register, the falsetto register, and the whistle register. This view is also adopted by many vocal pedagogists.

Vocal resonation

Vocal resonation is the process by which the basic product of phonation is enhanced in timbre and/or intensity by the air-filled cavities through which it passes on its way to the outside air. Various terms related to the resonation process include amplification, enrichment, enlargement, improvement, intensification, and prolongation, although in strictly scientific usage acoustic authorities would question most of them. The main point to be drawn from these terms by a singer or speaker is that the end result of resonation is, or should be, to make a better sound.

There are seven areas that may be listed as possible vocal resonators. In sequence from the lowest within the body to the highest, these areas are the chest, the tracheal tree, the larynx itself, the pharynx, the oral cavity, the nasal cavity, and the sinuses.

Chest voice and head voice

Chest voice and head voice are terms used within vocal music. The use of these terms varies widely within vocal pedagogical circles and there is currently no one consistent opinion among vocal music professionals in regards to these terms. Chest voice can be used in relation to the following:

• A particular part of the vocal range or type of vocal register
• A vocal resonance area
• A specific vocal timbre

Head voice can be used in relation to the following:

• A particular part of the vocal range or type of vocal register
• A vocal resonance area

History and development

The first recorded mention of the terms chest voice and head voice was around the 13th century, when it was distinguished from the "throat voice" (pectoris, guttoris, capitis — at this time it is likely that head voice referred to the falsetto register) by the writers Johannes de Garlandia and Jerome of Moravia. The terms were later adopted within bel canto, the Italian opera singing method, where chest voice was identified as the lowest and head voice the highest of three vocal registers: the chest, passagio and head registers. This approach is still taught by some vocal pedagogists today. Another current popular approach that is based on the bel canto model is to divide both men and women's voices into three registers. Men's voices are divided into "chest register", "head register", and "falsetto register" and woman's voices into "chest register", "middle register", and "head register". Such pedagogists teach that the head register is a vocal technique used in singing to describe the resonance felt in the singer's head.

However as knowledge of human physiology has increased over the past two hundred years, so has the understanding of the physical process of singing and vocal production. As a result, many vocal pedagogists, such as Ralph Appelman at Indiana University and William Vennard at the University of Southern California, have redefined or even abandoned the use of the terms chest voice and head voice. In particular, the use of the terms chest register and head register have become controversial since vocal registration is more commonly seen today as a product of laryngeal function that is unrelated to the physiology of the chest, lungs, and head. For this reason, many vocal pedagogists argue that it is meaningless to speak of registers being produced in the chest or head. They argue that the vibratory sensations which are felt in these areas are resonance phenomena and should be described in terms related to vocal resonance, not to registers. These vocal pedagogists prefer the terms chest voice and head voice over the term register. This view believes that the problems which people identify as register problems are really problems of resonance adjustment. It should be noted that this view is also in alignment with the views of other academic fields that study vocal registration including: speech pathology, phonetics, and linguistics. Although both methods are still in use, current vocal pedagogical practice tends to adopt the newer more scientific view. Also, some vocal pedagogists take ideas from both viewpoints.

The contemporary use of the term chest voice often refers to a specific kind of vocal coloration or vocal timbre. In classical singing, its use is limited entirely to the lower part of the modal register or normal voice. Within other forms of singing, chest voice is often applied throughout the modal register. Chest timbre can add a wonderful array of sounds to a singers vocal interpretive palette. However, the use of overly strong chest voice in the higher registers in an attempt to hit higher notes in the chest can lead to forcing. Forcing can lead consequently to vocal deterioration.

Classifying singing voices

In European classical music and opera, voices are treated like musical instruments. Composers who write vocal music must have an understanding of the skills, talents, and vocal properties of singers. Voice classification is the process by which human singing voices are evaluated and are thereby designated into voice types. These qualities include but are not limited to: vocal range, vocal weight, vocal tessitura, vocal timbre, and vocal transition points such as breaks and lifts within the voice. Other considerations are physical characteristics, speech level, scientific testing, and vocal registration. The science behind voice classification developed within European classical music and has been slow in adapting to more modern forms of singing. Voice classification is often used within opera to associate possible roles with potential voices. There are currently several different systems in use within classical music including: the German Fach system and the choral music system among many others. No system is universally applied or accepted.

However, most classical music systems acknowledge seven different major voice categories. Women are typically divided into three groups: soprano, mezzo-soprano, and contralto. Men are usually divided into four groups: countertenor, tenor, baritone, and bass. When considering voices of pre-pubescent children an eighth term, treble, can be applied. Within each of these major categories there are several sub-categories that identify specific vocal qualities like coloratura facility and vocal weight to differentiate between voices.

It should be noted that within choral music, singers voices are divided solely on the basis of vocal range. Choral music most commonly divides vocal parts into high and low voices within each sex (SATB). As a result, the typical choral situation affords many opportunities for misclassification to occur. Since most people have medium voices, they must be assigned to a part that is either too high or too low for them; the mezzo-soprano must sing soprano or alto and the baritone must sing tenor or bass. Either option can present problems for the singer, but for most singers there are fewer dangers in singing too low than in singing too high.

Within comtemporary forms of music (sometimes referred to as Contemporary Commercial Music), singers are classified by the style of music they sing, such as jazz, pop, blues, soul, country, folk, and rock styles. There is currently no authoritative voice classification system within non-classical music. Attempts have been made to adopt classical voice type terms to other forms of singing but such attempts have been met with controversy. The development of voice categorizations were made with the understanding that the singer would be using classical vocal technique within a specified range using unamplified (no microphones) vocal production. Since contemporary musicians use different vocal techniques, microphones, and are not forced to fit into a specific vocal role, applying such terms as soprano, tenor, baritone, etc. can be misleading or even inaccurate.

Vocal pedagogy

Vocal pedagogy, is the study of the teaching of singing. The art and science of vocal pedagogy has a long history that began in Ancient Greece and continues to develop and change today. Professions that practice the art and science of vocal pedagogy include vocal coaches, choral directors, vocal music educators, opera directors, and other teachers of singing. Typical areas of study include the following:

• Human anatomy and physiology as it relates to the physical process of singing.
• Breathing and air support for singing
• Phonation
• Vocal resonation or Voice projection
• Diction, vowels and articulation
• Vocal registration
• Sostenuto and Legato for singing
• Other singing elements, such as range extension, tone quality, vibrato, coloratura
• Vocal health and voice disorders related to singing
• Vocal styles, such as learning to sing opera, belt, or Art song
• Phonetics
• Voice classification

All of these different concepts are a part of developing proper vocal technique.

Vocal technique

Singing when done with proper vocal technique is an integrated and coordinated act that effectively coordinates the physical processes of singing. There are four physical processes involved in producing vocal sound: respiration, phonation, resonation, and articulation. These processes occur in the following sequence:

• 1. Breath is taken
• 2. Sound is initiated in the larynx
• 3. The vocal resonators receive the sound and influence it
• 4. The articulators shape the sound into recognizable units

Although these four processes are often considered separately when studied, in actual practice they merge into one coordinated function. With an effective singer or speaker, one should rarely be reminded of the process involved as their mind and body are so coordinated that one only perceives the resulting unified function. Many vocal problems result from a lack of coordination within this process.

Since singing is a coordinated act, it is difficult to discuss any of the individual technical areas and processes without relating them to the others. For example, phonation only comes into perspective when it is connected with respiration; the articulators affect resonance; the resonators affect the vocal folds; the vocal folds affect breath control; and so forth. Vocal problems are often a result of a breakdown in one part of this coordinated process which causes voice teachers to frequently focus in intensively on one area of the process with their student until that issue is resolved. However, some areas of the art of singing are so much the result of coordinated functions that it is hard to discuss them under a traditional heading like phonation, resonation, articulation, or respiration.

Once the voice student has become aware of the physical processes that make up the act of singing and of how those processes function, the student begins the task of trying to coordinate them. Inevitably, students and teachers, will become more concerned with one area of the technique than another. The various processes may progress at different rates, with a resulting imbalance or lack of coordination. The areas of vocal technique which seem to depend most strongly on the student's ability to coordinate various functions are. :

• 1. Extending the vocal range to its maximum potential
• 2. Developing consistent vocal production with a consistent tone quality
• 3. Developing flexibility and agility
• 4. Achieving a balanced vibrato

Developing the singing voice

Singing is not a natural process but is a skill that requires highly developed muscle reflexes. Singing does not require much muscle strength but it does require a high degree of muscle coordination. Individuals can develop their voices further through the careful and systematic practice of both songs and vocal exercises. Vocal pedagogists instruct their students to exercise their voices in an intelligent manner. Singers should be thinking constantly about the kind of sound they are making and the kind of sensations they are feeling while they are singing.

Exercising the singing voice

There are several purposes for vocal exercises, including:

• Warming up the voice
• Extending the vocal range
• "Lining up" the voice horizontally and vertically
• Acquiring vocal techniques such as legato, staccato, control of dynamics, rapid figurations, learning to comfortably sing wide intervals, singing trills, singing melismas and correcting vocal faults.

Extending the vocal range

An important goal of vocal development is to learn to sing to the natural limits of one's vocal range without any obvious or distracting changes of quality or technique. Vocal pedagogists teach that a singer can only achieve this goal when all of the physical processes involved in singing (such as laryngeal action, breath support, resonance adjustment, and articulatory movement) are effectively working together. Most vocal pedagogists believe in coordinating these processes by (1) establishing good vocal habits in the most comfortable tessitura of the voice, and then (2) slowly expanding the range.

There are three factors that significantly affect the ability to sing higher or lower:

1. The energy factor — In this usage, the word "energy" has several connotations. It refers to the total response of the body to the making of sound. It refers to a dynamic relationship between the breathing-in muscles and the breathing-out muscles known as the breath support mechanism. It also refers to the amount of breath pressure delivered to the vocal folds and their resistance to that pressure, and it refers to the dynamic level of the sound.
2. The space factor — "Space" refers to the amount of space created by the movement of the mouth and the position of the palate and larynx. Generally speaking, a singer's mouth should be opened wider the higher he or she sings. The internal space or position of the soft palate and larynx can be widened by relaxing the throat. Vocal pedagogists often describe this as feeling like the "beginning of a yawn".
3. The depth factor — In this usage, the word "depth" has two connotations. It refers to the actual physical sensations of depth in the body and vocal mechanism, and it refers to mental concepts of depth as related to tone quality.

McKinney says, "These three factors can be expressed in three basic rules: (1) As you sing higher, you must use more energy; as you sing lower, you must use less. (2) As you sing higher, you must use more space; as you sing lower, you must use less. (3) As you sing higher, you must use more depth; as you sing lower, you must use less."

Posture

The singing process functions best when certain physical conditions of the body exist. The ability to move air in and out of the body freely and to obtain the needed quantity of air can be seriously affected by the posture of the various parts of the breathing mechanism. A sunken chest position will limit the capacity of the lungs, and a tense abdominal wall will inhibit the downward travel of the diaphragm. Good posture allows the breathing mechanism to fulfill its basic function efficiently without any undue expenditure of energy. Good posture also makes it easier to initiate phonation and to tune the resonators as proper alignment prevents unnecessary tension in the body. Vocal pedagogists have also noted that when singer's assume good posture it often provides them with a greater sense of self assurance and poise while performing. Audiences also tend to respond better to singers with good posture. Habitual good posture also ultimately improves the overall health of the body by enabling better blood circulation and preventing fatigue and stress on the body.

Breathing and breath support

Natural breathing has three stages: a breathing-in period, a breathing out period, and a resting or recovery period; these stages are not usually consciously controlled. Within singing there are four stages of breathing:

1. a breathing-in period (inhalation)
2. a setting up controls period (suspension)
3. a controlled exhalation period (phonation)
4. a recovery period

These stages must be under conscious control by the singer until they becomed conditioned reflexes. Many singers abandon conscious controls before their reflexes are fully conditioned which ultimately leads to chronic vocal problems.

Vibrato

Vibrato is a technique used by singers (and many instrumentalists; for instance, string instruments that are played with a bow can produce vibrato tones) in which a sustained note actually wavers very quickly and consistently between a higher and a lower pitch, giving the note a slight quaver. Vibrato is the pulse or wave in a sustained tone. Vibrato may be developed through extensive vocal exercises, demonstrated in vocal training programs.

Vibrato adds richness to the tone. Faster vibratos are possible without perceived "damage" to the note as the frequency of the note increases. Slow vibrato is necessary for low frequencies in order to allow the full waveform to propagate before altering its frequency.

Vibrato is the result of proper breath support. Some singers use vibrato as a means of expression. Many successful artists have built a career on deep, rich vibrato ability. Pop and R&B Divas Whitney Houston and Soul legend Patti LaBelle often uses vibrato in their voices to express emotion.

Vocal music

Vocal music is music performed by one or more singers, with or without non-vocal instrumental accompaniment, in which singing provides the main focus of the piece. Music which employs singing but does not feature it prominently is generally considered instrumental music. Vocal music typically features sung words called lyrics, although there are notable examples of vocal music that are performed using non-linguistic syllables or noises, sometimes as musical onomatopoeia. A short piece of vocal music with lyrics is broadly termed a song.

Vocal music is probably the oldest form of music, since it does not require any instrument besides the human voice. All musical cultures have some form of vocal music and there are many long standing singing traditions throughout the world's cultures.

Genres of vocal music

Vocal music is written in many different forms and styles which are often labeled within a particular genre of music. These genres include: Art music, Popular music, Traditional music, Regional and national music, and fusions of those genres. Within these larger genres are many sub-genres. For example, popular music would encompass blues, jazz, country music, easy listening, hip hop, rock music, and several other genres. There may also be a sub-genre within a sub-genre such as vocalese and scat singing in jazz.

Lead and backing vocalists

In many modern musical groups, a lead singer performs the primary vocals or melody of a song, as opposed to a backing singer who sings backup vocals or the harmony of a song. Backing vocalists sing some, but usually not all, parts of the song often singing only in a song's refrain or humming in the background. An exception is five-part gospel a cappella music, where the lead is the highest of the five voices and sings a descant, and not the melody. Some artists may sing both lead and backing vocals on audio recordings by overlaping recorded vocal tracks.

Health effects of singing

Singing is considered by some to have positive effects on peoples' health. A preliminary study based on self-reported data from a survey of students participating in choral singing found perceived physical benefits including increased lung capacity, improved mood, stress reduction, as well as perceived social and spiritual benefits. However, one much older study of lung capacity compared those with professional vocal training to those without, and failed to back up the claims of increased lung capacity.

Singing may positively influence the immune system through the reduction of stress. One study found that both singing and listening to choral music reduces the level of stress hormones and increases immune function.
