The Selective Service System is an independent federal agency within the Executive Branch of the federal government of the United States. The Director of the Selective Service System reports directly to the President of the United States of America.he Military Selective Service Act of 1967 (Selective Service Act of 1948) expanded the ages of conscription to the ages of 18 to 35. It still granted student deferments, but ended them upon either the student's completion of a four-year degree or his 24th birthday, whichever came first.
String quartet. A string quartet is a musical ensemble of four string players â two violin players, a viola player and a cellist â or a piece written to be performed by such a group. The string quartet is one of the most prominent chamber ensembles in classical music, with most major composers, from the mid to late 18th century onwards, writing string quartets.
Most theorists trace the string quartet as having evolved from the Baroque trio sonata, which consisted of two melodic upper lines and a continuo of varying instrumentation comprised of virtually any lower voices (most often a harpsichord, but also organs, cellos, lutes or bassoons) to provide the harmonic base.
