Which Composers Have Expanded the Technical Range of Your Instrument ? Discuss Why This Is Necessary, Giving Examples .

Piano is a large keyboard musical instrument with a wooden case enclosing a soundboard and metal strings, which are struck by hammers when the keys are depressed. The strings' vibration is stopped by dampers when the keys are released, and it can be regulated for length and volume by two or three pedals.
