MezzoForte means Zhongqiang, which is the abbreviation of MezzoForte. Mf is a term for music dynamics, which reflects the strength of the tone. Musical terminology makes it easier to express content. Intensity is the degree of sound intensity. Like the sound range, it is also a relative concept and cannot simply be measured by the decibel unit standard in physics.

The term dynamics refers to the intensity of the notes in a score or musical performance, or the intensity of the sounds. The control of intensity during performance must be unified with the content of the music. Only when you have feelings in your heart and are moved can you discover the most beautiful sound and express the performer's artistic understanding and experience of the work through changes in intensity.

Dynamic markings are usually in Italian musical terms. The composer of the music usually marks the dynamics in great detail on the score, which can usually be divided into many levels, from the weakest to the strongest. The intensity of each level is a relative value. There are more than a dozen levels of this type. This allows the performer to intuitively understand how the music is played while playing. Musical terminology makes it easy to understand the characteristics of a piece.

The intensity of music should be the intensity of the sound, not the intensity of the sound. Sound and sound are two different things. In MIDI music, the velocity in the MIDI protocol is the speed of our keystrokes. The velocity value ranges from 0-127, divided into 8 levels, and the hexadecimal system is 00-7F.
