Chapter 84 orderliness

In music, a unit of time is called a beat.The length of the beat is relative. For example, in the Allegro, the unit length of the beat is short, and in the Adagio music, the unit length of the beat is long.In a piece of music, the strength of each beat is not the same, but a regular change in intensity. In Western music, it is called "beat", and the piece is divided into measures by bar lines, such as Two beats are called "two beats", three beats are called "three beats", four beats are called "four beats" and so on.The purpose of dividing subsections is to indicate the changing law of strength and weakness.For example, two beats are the cycle of "strong and weak"; three beats are the cycle of "strong, weak and weak";

In traditional Chinese music, different arrangements of "bans" and "eyes" are used to represent different beats, or to represent different changes in strength and weakness.Every single glance counts as one shot.The so-called "ban" is a strong sound; the so-called "eye" is a weak sound.For example, when we see "one board and three eyes", we know that the change of strength of this piece of music is "strong, weak, weak, weak", which is equivalent to the "four beats" in modern music.Then "one eye at a time" is equivalent to the "two beats" of "strong and weak" changes, and the rest can be deduced by analogy.In music, there are two more special cases.One is that there is no eye, that is, all the beats are strong beats, such as "pallets" in drama.The other is loose board with free rhythm without boarding.
