Duration is the length of sound in time. The varying length of sounds in time creates rhythm, and these variations are what make compositions interesting. In music, time is indicated by symbols we call notes. Intensity means the loudness and softness of a sound produced by the varying degrees of pressure applied to the instrument producing the sound. It evokes the emotional features in music as music moves from loud to soft and vice versa. Symbolic indications of intensity are often written in Italian likeliest (loudly), fortissimo (very loudly), piano (softly) and pianissimo (very botfly).
Indications of softness and loudness are written as crescendo(becoming louder), decrescendo (decrease loudness) or diminuendo(becoming softer). Pianoforte is the longer name of piano, because it was an innovative instrument in the 17th century Italy that allowed the dynamics of softness (piano) and loudness (forte) to be reproduced by its mechanisms.
