Dynamics. Dynamics in music refers to how loud or soft is the music. It is that simple! But, because musicians and composers like to make things interesting, and sometimes difficult, there are lots of different musical terms that can be used to describe what the dynamics are in a piece of music. Usually, the music terms used to describe dynamics are called “Italian terms”. Many, many years ago, when music in the Western European tradition started to become systematized, it was decided that all musical information written on the musical score would be in a common language – Italian. Dynamics in Music Definitions In the chart you can see all the basic dynamics terms commonly used in music today. Essentially, dynamics fall into two main categories – loud or soft. The dynamic music definitions will go from the softest to the loudest Italian terms. In real life, music that is performed very, very soft or “pianississimo” would be almost at a whisper. Whereas music performed very, very loudly or “fortississimo” would be music that is deafening and as loud as possible for the instrument or ensemble as a whole. Pianississimo – very, very soft Pianissimo – very soft Piano – soft Mezzo piano – a little soft Mezzo forte – a little loud Forte – loud Fortissimo – very loud Fortissimo – very, very loud
