Dynamics were rarely used in the Baroque and Classical periods. In the Romantic period and beyond dynamics were used to create dramatic effects.
Dynamics beyond pp and ff are used occasionally. Tchaikovsky used ppp and fff to emphasise important moments. Holst uses ffff in Mars from The Planets, Tchaikovsky uses pppppp for a bassoon solo in his Path茅tique Symphony.
Interpretation
Dynamics indicate a composer鈥檚 intentions. However, each conductor鈥檚 or performer鈥檚 interpretation of a dynamic will be different. 鈥楩orte鈥 does not mean a certain number of decibels - it will be interpreted by the performer to express the music. Dynamics are a way of indicating expression and musicality, not just how loudly or quietly music should be played.
