dynamics explained

Dynamics are the variations in loudness and softness that give music its expressive shape.‍​‍​‌​‌​‌​‌​‌​‍​‍​‌​‌​‍​‌​‌​‍​‍​‌​‍​‍​‌​‌​‍​‍​‌​‌​‌​‌​‍​‌​‌​‍​‌ The standard dynamic markings, derived from Italian, form a spectrum from silence to maximum volume: pianississimo (ppp), pianissimo (pp), piano (p), mezzo-piano (mp), mezzo-forte (mf), forte (f), fortissimo (ff), and fortississimo (fff). Crescendo indicates a gradual increase in volume, while decrescendo (or diminuendo) indicates a gradual decrease. Sudden dynamic changes include sforzando (a sharp accent), forte-piano (loud then immediately soft), and subito piano (suddenly soft). Dynamics are relative, not absolute — a fortissimo from a solo flute is quieter than a piano from a full orchestra. Effective use of dynamics is one of the most powerful tools for musical expression, creating drama, intimacy, excitement, and surprise.
