A sudden change in the level of sound

Explanation:

Sforzando refers to a composer's indication of the score of the sound intensity with which he wants a note or an entire piece of music to be performed. Physically, a musical sound has three characteristics: height, intensity and timbre. Height is the frequency of the sound, indicated by the composer by the position of the note in the pentagram. Timbre is the characteristic that allows us to distinguish between a note of the same height and intensity produced by different instruments, such as a flute or a violin. Sound intensity refers to the energy with which the sound wave hits our ears. To indicate the sound intensity with which he wants a note or piece of music to be performed, the composer uses a gradation that goes from the pianissimo molto to the fortissimo molto.
