Kitab Al-Musiki Al-Kabir
''Kitab al-Musiqa al-Kabir'' (, ) is a treatise on music in Arabic by the Islamic Golden Era philosopher al-Farabi (872–950/951). The work prescribes different aspects of music such as maqamat, and is believed to be influenced by the Pythagorean theory of harmonic ratios. The book was translated into Hebrew by Joseph ben Judah ibn Aknin. Content Al-Farabi divided Kitab al-Musiqa al-Kabir into two treatises. The first treatise is composed of two parts; following the Aristotelian tradition, al-Farabi split his study of music into a theoretical and practical aspect: * The first part, which consists of two discourses, is an introduction which establishes the theoretical principles of music and investigation into how sound is generated. * The second part applies the theoretical principles established in the first part to the musical instruments that were in use during al-Farabi’s time, while also discussing musical intervals and different kinds of melodies.

Discourse
Discourse is a generalization of the notion of a conversation to any form of communication. Discourse is a major topic in social theory, with work spanning fields such as sociology, anthropology, continental philosophy, and discourse analysis. Following work by Michel Foucault, these fields view discourse as a system of thought, knowledge, or communication that constructs our world experience. Since control of discourse amounts to control of how the world is perceived, social theory often studies discourse as a window into Power (social and political), power. Within theoretical linguistics, discourse is understood more narrowly as linguistic information exchange and was one of the major motivations for the framework of dynamic semantics. In these expressions, denotations are equated with their ability to update a discourse context. Social theory In the humanities and social sciences, discourse describes a formal way of thinking that can be expressed through language. Discourse i ...

Music Of The Medieval Islamic World
Music is the arrangement of sound to create some combination of form, harmony, melody, rhythm, or otherwise expressive content. Music is generally agreed to be a cultural universal that is present in all human societies. Definitions of music vary widely in substance and approach. While scholars agree that music is defined by a small number of specific elements, there is no consensus as to what these necessary elements are. Music is often characterized as a highly versatile medium for expressing human creativity. Diverse activities are involved in the creation of music, and are often divided into categories of composition, improvisation, and performance. Music may be performed using a wide variety of musical instruments, including the human voice. It can also be composed, sequenced, or otherwise produced to be indirectly played mechanically or electronically, such as via a music box, barrel organ, or digital audio workstation software on a computer. Music often plays a key r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
10th-century Arabic-language Books
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Commentary (philology)
In philology, a commentary is a line-by-line or even word-by-word explication usually attached to an edition of a text in the same or an accompanying volume. It may draw on methodologies of close reading and literary criticism, but its primary purpose is to elucidate the language of the text and the specific culture that produced it, both of which may be foreign to the reader. Such a commentary usually takes the form of footnotes, endnotes, or separate text cross-referenced by line, paragraph or page. Means of providing commentary on the language of the text include notes on textual criticism, syntax and semantics, and the analysis of rhetoric, literary tropes, and style. The aim is to remove, lessen or point out linguistic obstacles to reading and understanding the text. If a text is historical, or is produced within a culture assumed to be of limited familiarity to a reader, a broader range of issues may require elucidation. These include, but are by no means limited to, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melody
A melody (), also tune, voice, or line, is a linear succession of musical tones that the listener perceives as a single entity. In its most literal sense, a melody is a combination of Pitch (music), pitch and rhythm, while more figuratively, the term can include other musical elements such as Timbre, tonal color. It is the foreground to the background accompaniment. A line or Part (music), part need not be a foreground melody. Melodies often consist of one or more musical Phrase (music), phrases or Motif (music), motifs, and are usually repeated throughout a Musical composition, composition in various forms. Melodies may also be described by their melodic motion or the pitches or the interval (music), intervals between pitches (predominantly steps and skips, conjunct or disjunct or with further restrictions), pitch range, tension (music), tension and release, continuity and coherence, cadence (music), cadence, and shape.

Interval (music)
In music theory, an interval is a difference in pitch between two sounds. An interval may be described as horizontal, linear, or melodic if it refers to successively sounding tones, such as two adjacent pitches in a melody, and vertical or harmonic if it pertains to simultaneously sounding tones, such as in a chord. In Western music, intervals are most commonly differences between notes of a diatonic scale. Intervals between successive notes of a scale are also known as scale steps. The smallest of these intervals is a semitone. Intervals smaller than a semitone are called microtones. They can be formed using the notes of various kinds of non-diatonic scales. Some of the very smallest ones are called commas, and describe small discrepancies, observed in some tuning systems, between enharmonically equivalent notes such as C and D. Intervals can be arbitrarily small, and even imperceptible to the human ear. In physical terms, an interval is the ratio between two sonic fr ...

Musical Instrument
A musical instrument is a device created or adapted to make Music, musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. A person who plays a musical instrument is known as an ''#Instrumentalist, instrumentalist''. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for rituals, such as a horn (music), horn to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melody, melodies for entertainment. Musical instruments evolved in step with changing applications and technologies. The exact date and specific origin of the first device considered a musical instrument, is widely disputed. The oldest object identified by scholars as a musical instrument, is Divje Babe flute, a simple flute, dated back 50,000–60,000 years. Many scho ...

Sound
In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the brain. Only acoustic waves that have frequency, frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of to . Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges, allowing some to even hear ultrasounds. Definition Sound is defined as "(a) Oscillation in pressure, stress, particle displacement, particle velocity, etc., propagated in a medium with internal forces (e.g., elastic or viscous), or the superposition of such propagated oscillation.
