In music, dynamics are instructions in musical notation to the performer about the loudness at which to play a note or phrase. More generally, dynamics may also include other aspects of the execution of a given piece.

More subtle degrees of loudness or softness are indicated by:

Use of up to three consecutive fs or ps is also common:

The overall ranking of these is:

A less common dynamic marking used especially by Johannes Brahms is:

Some pieces contain dynamic designations with more than three consecutive fs or ps. In Holst's The Planets, ffff occurs twice in "Mars" and once in "Uranus", often punctuated by organ, and fff occurs several times throughout the work. It also appears in Heitor Villa-Lobos' Bachianas Brasileiras No. 4 (Prelude), and in Liszt's Fantasy and Fugue on the chorale "Ad nos, ad salutarem undam". The Norman Dello Joio Suite for Piano ends with a crescendo to a ffff, and Tchaikovsky indicated a bassoon solo pppppp (6 p) in his Pathétique Symphony and ffff in passages of his 1812 Overture and the 2nd movement of his Fifth Symphony.
