Loop is an English term that the Royal Spanish Academy ( RAE ) does not include in its dictionary, although it is often used in various ways in our language. The concept can be translated as loop or loop .
In the field of music , a sound or a set of sounds that repeat continuously is called a loop. These are between one and four measures that are repeated throughout a song.
Loops are samples : fragments of sound that are recorded for later reuse. In electronic music , for example, the use of samples is common for the development of musical themes. When it is a loop, the sample is repeated over and over again.
In the same way, we cannot ignore that there is also what is known as a loop station. It is a device that is used in the field of music. Specifically, it is a recorder that allows you to record short phrases and then add layers one above the other.
This tool is put into operation thanks to a pedal. Thus, by stepping on this, a few measures are recorded, then these begin to repeat cyclically and while that happens, more can be recorded to superimpose them on the previous ones.
There are numerous musicians who have resorted to using this device and among them is, for example, the English singer Ed Sheeran, known for singles like "Thinking Out Loud."
Among the advantages that come with using the loop station are that it allows you to record yourself on several occasions, that it gives the possibility of not only recording voices but also instruments and that it even usually has a wide variety of sound effects. Among the latter, for example, the Flanger stands out, which gives what is an oscillating and metallic sound to the voice, or the Delay, which is identified as an echo effect.
In the field of programming , a loop is code that a statement executes repeatedly . This repetition is maintained until the condition assigned to the loop is no longer met. The do-while loop and the while loop are among the most used.
Programming often requires the repeated execution of a series of instructions. Code duplication is not the best alternative as it increases the file extension and causes difficulties in case the code needs to be updated. In this context, the loop appears as a convenient option.
For graph theory , a loop is an edge that enables the connection of a vertex with itself. In the case of simple graphs, they do not have loops.
In English we also talk about the Loop of Henle. This term refers to the so-called loop of Henle. This is a kind of fork-like tube that exists in the kidney and is located specifically in the so-called nephron. This is what is responsible for purifying the blood in the aforementioned organ.
