Rhythmic Unit
Rhythm (from Greek , ''rhythmos'', "any regular recurring motion, symmetry") generally means a " movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions". This general meaning of regular recurrence or pattern in time can apply to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything from microseconds to several seconds (as with the riff in a rock music song); to several minutes or hours, or, at the most extreme, even over many years. Rhythm is related to and distinguished from pulse, meter, and beats: In the performance arts, rhythm is the timing of events on a human scale; of musical sounds and silences that occur over time, of the steps of a dance, or the meter of spoken language and poetry. In some performing arts, such as hip hop music, the rhythmic delivery of the lyrics is one of the most important elements of the style. Rhythm may also refer to visual presentation, as "timed mov ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jonathan Kramer
Jonathan Donald Kramer (December 7, 1942, Hartford, Connecticut – June 3, 2004, New York City) was an American composer and music theorist.

His composition teachers included Karlheinz Stockhausen, Roger Sessions, Leon Kirchner, Seymour Shifrin, Andrew Imbrie, Richard Felciano, Jean-Claude Éloy, Billy Jim Layton, Edwin Dugger, and Arnold Franchetti. He studied theory with David Lewin, criticism with Joseph Kerman, and computer music with John Chowning. Kramer was professor of composition and theory at Columbia University from 1988 until his death in 2004. He also taught at the Oberlin Conservatory, Yale University, and the University of Cincinnati College-Conservatory of Music. He held visiting appointments at Wesleyan University, King's College London, the Canberra School of Music, the School of Music ...

Collective Identity
Collective identity is the shared sense of belonging to a group. In sociology In 1989, Alberto Melucci published ''Nomads of the Present'', which introduces his model of collective identity based on studies of the social movements of the 1980s. Melucci based his ideas on the writings by Touraine (1925- ) and Pizzorno (1924-2019), specifically their ideas on social movements and collective action respectively. Alberto Melucci writes: "collective identity is an interactive and shared definition produced by several individuals (or groups at a more complex level) and concerned with the orientation of action and the field of opportunities and constraints in which the action takes place". Unsatisfied with the gap between theories on how collective actions form and how individuals find motivation, Melucci defines an intermediate process, in which individuals recognize that they share certain orientations in common and on that basis decide to act together. He considers collective iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drilling
Drilling is a cutting process where a drill bit is spun to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute. This forces the cutting edge against the work-piece, cutting off chips (swarf) from the hole as it is drilled. In rock drilling, the hole is usually not made through a circular cutting motion, though the bit is usually rotated. Instead, the hole is usually made by hammering a drill bit into the hole with quickly repeated short movements. The hammering action can be performed from outside the hole ( top-hammer drill) or within the hole (down-the-hole drill, DTH). Drills used for horizontal drilling are called drifter drills. In rare cases, specially-shaped bits are used to cut holes of non-circular cross-section; a square cross-section is possible. Process Drilled holes are char ...
