Broken bow is also called "maintained tone", and its symbol is "-", which is written above the note. Broken bow, as the name suggests, is also a bowing technique for breaking notes.

The similarities between the broken bow and the ten bow are: whether it is a separate bow or a slurred bow, the sound should be disconnected from the sound.

The difference between them is:

1. The pronunciation of Broken Bow is slightly longer than that of Dun Bow.

2. Broken bow requires the same strength when pronouncing, without elasticity. The Dun bow requires the pronunciation to be short and flexible.

3. In terms of playing method, breaking the bow requires the fingers of the right hand to maintain the strength of the bow at all times and cannot be loosened. Its pause is achieved by the stop of the bow movement, and there is no change in the pressure of the bow hair on the string. Therefore, the pronunciation is in the shape of line segments parallel to the head and tail. The pronunciation of the bow is elastic and dot-like.

Broken bow is the same as Dun bow. There are also split bows (that is, one bow is played with one broken bow) and continuous broken bows (that is, one bow is played with multiple broken bows). When playing a slurred bow, pay attention to the bow hair always sticking to the strings, and in the slurred state, the interval between notes is completed by the even pause of the bow.
