Flaked stone reduction involves the use of a hard hammer percussor, such as a hammerstone, a soft hammer fabricator (made of wood, bone or antler), or a wood or antler punch to detach lithic flakes from the lithic core. As flakes are detached in sequence, the original mass of stone is reduced; hence the term for this process.
Fundamental elements for the technic description of a lithic flake. In archaeology, a lithic flake is a "portion of rock removed from an objective piece by percussion or pressure," [1]: 255 and may also be referred to as simply a flake, or collectively as debitage.
Music can be analysed by considering a variety of its elements, or parts (aspects, characteristics, features), individually or together. A commonly used list of the main elements includes pitch, timbre, texture, volume, duration, and form. The elements of music may be compared to the elements of art or design.
An orchestral reduction is a sheet music arrangement of a work originally for full symphony orchestra (such as a symphony, overture, or opera), rearranged for a single instrument (typically piano or organ), a smaller orchestra, or a chamber ensemble with or without a keyboard (e.g. a string quartet).
The flakes are shaped using the lithic reduction techniques, allowing for creation of various tools such as arrowheads and handaxes. Two stone characteristics will determine whether one is able to chip away large enough flakes to make tools out of: whether the stone is of a cryptocrystalline structure, and how conchoidally the stone fractures ...
Although in music instruction certain styles or repertoires of music are often identified with one of these descriptions this is basically added music [clarification needed] (for example, Gregorian chant is described as monophonic, Bach Chorales are described as homophonic and fugues as polyphonic), many composers use more than one type of ...
The term Paleo-Indians applies specifically to the lithic period in the Western Hemisphere and is distinct from the term Paleolithic. [note 1] Traditional theories suggest that big-animal hunters crossed the Bering Strait from North Asia into the Americas over a land bridge . This bridge existed from 45,000 to 12,000 BCE (47,000–14,000 BP). [1]
Lithic reduction is the removal of a lithic flake from a larger stone in order to reach the desired tool shape and size. The beginning stone is called the flake lithic core. There are three steps to lithic reduction: Hard hammer percussion is the first step. It involves knocking off the larger flakes to achieve the desired lithic core for the ...
