Members of the western concert flute family the instrument is a prototype built for Italian flautist Roberto Fabbriciani by Francesco Romei, a Florentine craftsman. Members of the western concert flute family The western concert flute family has a wide range of instruments. The piccolo is the highest-pitched member of the flute family, with a range an octave above that of the concert flute. It is usually the highest-pitched instrument within orchestras and bands. The piccolo has a stereotype for being difficult to play in tune; its small size makes it difficult to construct an evenly tuned scale. The treble flute is pitched in the key of G,
Smallest-circle problem Smallest-circle problem The smallest-circle problem or minimum covering circle problem is a mathematical problem of computing the smallest circle that contains all of a given set of points in the Euclidean plane. The corresponding problem in "n"-dimensional space, the smallest bounding-sphere problem, is to compute the smallest "n"-sphere that contains all of a given set of points. The smallest-circle problem was initially proposed by the English mathematician James Joseph Sylvester in 1857. The smallest-circle problem in the plane is an example of a facility location problem (the 1-center problem) in which the location of a new facility must be chosen
