The Hershey's Bar is the most basic chocolate by Hershey's. It is a bar made of hardened chocolate. A fact that most do not know, the wrapper is actually a darker maroon color and not, in fact, a chocolate brown as the bar itself. Mini sized version. The candy and wrapper.
Sonata form (also sonata-allegro form or first movement form) is a large-scale musical structure used widely since the middle of the 18th century (the early Classical period).
1 Some are in one movement; I know one symphony in 24 very short movements. Many composers have abandoned the usual forms altogether.  Variations on Sonata form in chamber music begin with Beethoven, who wrote some Piano Sonatas that are not really in Sonata form at all.
