Pizzicato
Pizzicato means:  playing a string instrument by plucking the strings (pulling a string with the finger and letting go quickly).  Instruments such as the violin, viola, cello and double bass are normally played with a bow, but if the composer wants the player to pluck instead of bow, the word “pizzicato” or just “pizz” is written in the music.  When the player has to play with the bow again the word “arco” is written in the music (“arco” is the Italian word for “bow”).
