Here's why:
* Historical Influence: Italian was the language of opera and classical music during the Baroque period (1600-1750). Many musical terms, including those for dynamics, originated in Italian.
* International Standard: The Italian terms have become the standard way to express dynamics in music around the world, even for composers and musicians who don't speak Italian.
Examples of Italian dynamic markings:
* Piano (p): Soft
* Forte (f): Loud
* Mezzo forte (mf): Moderately loud
* Pianissimo (pp): Very soft
* Fortissimo (ff): Very loud
