From the Latin emissio , the term emission is related to the action and effect of emitting (throwing or casting something out, putting securities or securities into circulation, expressing an opinion or judgment, launching Hercian waves to disseminate information ).
An issue, therefore, can be constituted by the set of public securities or other types of securities that are put into circulation. For example: "Telefónica has announced the issuance of one million new shares for a total value that exceeds ten million euros," "The issuance of debt is the only alternative we have left to save the company."
Television or radio programs are also usually called a broadcast: "In today's broadcast we will have the presence of the last champion of the Paris Open" , "Next Friday's broadcast will be postponed, given that the municipal elections will take place" .
polluting emissions
Polluting emissions , on the other hand, are the waste that is emitted by human activity, whether industrial or domestic, and that affects the environment. The emission of toxic gases by cars is known as vehicular emission , and contributes considerably to the formation of smog in cities, which makes it difficult to breathe, as well as the recovery and care of those suffering from diseases such as asthma.
Atmospheric emissions are made up of the set of substances that are released into the atmosphere, such as carbon dioxide, nitrogen oxide, carbon monoxide and sulfur dioxide. This definition implies that the pollution produced by cars is part of both vehicle emissions and atmospheric emissions, which shows the breadth of this type of categories.
The concept applied to singing
With respect to music , sound emission is a fundamental topic that every musician must study and that varies for each instrument. In the case of singing, people often talk about the throat of great singers, attributing qualities to it, believing that it is the most important component of their body; But reality shows us that the vocal cords (the part of the body referred to, imprecisely, when the "throat" is mentioned) represent a small percentage of the complete picture of a voice professional.
Although not all singers and singing teachers agree on the hierarchy of the different concepts that revolve around the emission of the voice , breathing is usually considered very important by a large majority; The air that comes out of the lungs is the only element that makes contact with the vocal cords, to make them vibrate and generate what, later, will become notes.
Breathing in sound emission
One of the most important points to keep in mind when breathing while playing a song is the amount of air needed; If you inhale excessively, it is more difficult to retain and manage the air , which is why it is likely to escape and exert too much force on the vocal cords, or generate greater exhaustion than expected and this will affect the performance. To begin the process of correct vocal sound emission, it is essential to learn to use small portions of air, as necessary at any given moment.
Once breathing is controlled, it is necessary to make use of the resonators present in our body , bony parts such as our cheekbones and our ribs, to ring, beautify and efficiently project each of the sounds we produce. The healthy emission of the voice is characterized by the absence of fatigue and discomfort after singing, and by a flow of sound that does not require the use of a microphone, given the intelligent use of the natural amplifiers we have.
