Concert

A concert is a live music performance in front of an audience.

The performance may be by a single musician, sometimes then called a recital, or by a musical ensemble, such as an orchestra, choir, or band. Concerts are held in a wide variety and size of settings, from private houses and small nightclubs, dedicated concert halls, entertainment centres and parks to large multipurpose buildings, and even sports stadiums. Indoor concerts held in the largest venues are sometimes called arena concerts or amphitheatre concerts. Informal names for a concert include show and gig.

Regardless of venue, musicians usually perform on a stage. Concerts often require live event support with professional audio equipment. Before recorded music, concerts provided the main opportunity to hear musicians play.

Types

The nature of a concert varies by musical genre, individual performers, and the venue. Concerts by a small jazz combo or small bluegrass band may have the same order of program, mood, and volume—but vary in music and dress. In a similar way, a particular musician, band, or genre of music might attract concert attendees with similar dress, hairstyle, and behavior. For example, concert goers in the 1960s often had long hair (sometimes in dread lock form), sandals and inexpensive clothing made of natural fibers. Regular attendees to a concert venue might also have a recognizable style that comprises that venue's scene.

Form of the Good

Plato describes "The Form of the Good", or more literally "the idea of the good" (ἡ τοῦ ἀγαθοῦ ἰδέα), in his dialogue the Republic (508e2–3), speaking through the character of Socrates. Plato introduces several forms in his works, but identifies the Form of the Good as the superlative. This form is the one that allows a philosopher-in-training to advance to a philosopher-king. It cannot be clearly seen or explained, but once it is recognized, it is the form that allows one to realize all the other forms.

Usages in The Republic

The first references we see in The Republic to the Form of the Good can be found within the conversation between Glaucon and Socrates (454 c–d). When trying to answer such difficult questions pertaining to the definition of justice, Plato identifies that we should not “introduce every form of difference and sameness in nature” instead we must focus “on the one form of sameness and difference that was relevant to the particular ways of life themselves” which is the Form of the Good. This Form is the basis for understanding all other Forms, it is what allows us to understand everything else. Through the conversation between Socrates and Glaucon (508 a–c) Plato analogizes the Form of the Good with the sun as it is what allows us to see things. Here, Plato describes how the sun allows for sight. But he makes a very important distinction, “sun is not sight” but it is “the cause of sight itself.” As the sun is in the visible realm, the Form of Good is in the intelligible realm. It is “what gives truth to the things known and the power to know to the knower”. It is not only the “cause of knowledge and truth, it is also an object of knowledge”.

Music

Music is an art form and cultural activity whose medium is sound and silence. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and with vocal techniques ranging from singing to rapping, and there are solely instrumental pieces, solely vocal pieces and pieces that combine singing and instruments. The word derives from Greek μουσική (mousike; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound."

Radio

Radio is the use of radio waves is to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.

Radio systems need a transmitter to modulate (change) some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation (which can be frequency modulation or phase modulation). Radio systems also need an antenna to convert electric currents into radio waves, and vice versa. An antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected. The electromagnetic wave is intercepted by a tuned receiving antenna. A radio receiver receives its input from an antenna and converts it into a form usable for the consumer, such as sound, pictures, digital data, measurement values, navigational positions, etc. Radio frequencies occupy the range from a 3 kHz to 300 GHz, although commercially important uses of radio use only a small part of this spectrum.
