The bass is an instrument with profound musical heritage and rich expressive power.

The shape of a bass guitar is very similar to that of an ordinary electric guitar, slightly heavier, and the scale is in the bass position, so the strings are quite thick and the string tension is quite large, so the power of picking the strings is much greater than that of a guitar.

In the composition of a modern electroacoustic band, the bassist is responsible for playing heavy bass and rhythm, and is the bass part of the entire band. In a jazz band, the bass can be said to be the cornerstone of the entire band. In terms of harmony, it is the guide of the melody part. In terms of rhythm, it is the conductor of everyone. The quality of the bass player directly affects the effect of the band.
