The musical term subito means suddenly and quickly. It is usually used with the terminology of speed and velocity. Add "s" before the velocity mark to represent the Italian "subito". For example, Fortesubito (abbreviated as fsub.) suddenly becomes strong; Pianosubito (abbreviated as psub.) suddenly becomes weak.

In music, intensity is an important means of musical expression. Intensity is not volume. Intensity will cause the volume to increase, but the increase in volume does not depend on the increase in intensity. The intensity is determined by the amplitude. Different amplitudes determine the intensity, that is, the strength of the sound.

Dynamics is reflected in the intensity of the beat in music. That is to say, the basic strength and weakness laws of each rhythm must be followed when playing and singing, and cannot be changed at will. Just imagine if the two-beat music is sung into a three-beat rhythm, it will cause confusion.

The dynamics in the rhythm. That is, the different intensity patterns produced by the rhythm types in each beat (or every two or three beats). Such as two notes per beat, three notes per beat, dotted rhythm, syncopated rhythm, triplet, etc.

The dynamics implicit in the melody. Generally speaking, an upward pitch (ascending) will produce passionate, high emotions, followed by a gradual change in intensity; a downward pitch (downward) will produce low, negative emotions, followed by a gradual decrease in intensity. change. We must understand the characteristics of this melody progression and follow this pattern in music performance and singing, so that we can have a good musical expression.
