A flat can be described by a system of linear equations.For example, a line in two-dimensional space can be described by a single linear equation involving x and y: + = In three-dimensional space, a single linear equation involving x, y, and z defines a plane, while a pair of linear equations can be used to describe a line.
In music, flat means lower in pitch. It may either be used generically, meaning any lowering of pitch, or refer to a particular size: lowering pitch by a chromatic semitone. A flat is the opposite of a sharp (♯) which raises pitch by the same amount that a flat lowers it. ♭
For instance, he is very well known for playing an F major scale during a song written in G major (the F major scale, when played from G to G, is a G Dorian mode). The use of this technique introduces the flat 3rd (Bb) and the flat 7th (F) over the G chord which has a unique sound popular in bluegrass.
The definition of a flat morphism of schemes results immediately from the local property of flatness. A morphism : of schemes is a flat morphism if the induced map on local rings , (), is a flat ring homomorphism for any point x in X.
A flat (short for scenery flat) or coulisse is a flat piece of theatrical scenery which is painted and positioned on stage [1] so as to give the appearance of buildings or other background. Flats can be soft covered (covered with cloth such as muslin ) or hard covered (covered with decorative plywood such as luan).
This period of art is identified by art forms consisting of an image on a flat two-dimensional surface. This art evolution began in the 1860s and culminated 50 years later. By this time almost all three-dimensional works had been eliminated. This new approach to painting was to create a visual appearance of realism.
A lower-rise apartment building on the left side of the Avenue of the Americas in Manhattan, juxtaposed next to a skyscraper apartment building. An apartment (American English, Canadian English), flat (British English, Indian English, South African English) [a], or unit (Australian English) is a self-contained housing unit (a type of residential real estate) that occupies part of a building ...
