Singer: The sign and appearance of the entire band is a bridge of communication between the band and the audience. It can drive the enthusiasm of the audience and stimulate the desire for performance of teammates. A good lead singer can save the band a lot of trouble. . In addition, the lead singer must be a thinker with a unique vision and a sharp perspective on issues, and must be able to write lyrics that are deeply touching and have a certain provocative atmosphere. Bassist: In addition to vocals, the person in the band who can connect the melody and rhythm. What the bassist has to do is to replace the drums when the drummer is not here, and to replace the guitar when the guitarist is not here, so that others can feel the bass. The rhythm is very comfortable, making your whole body sway involuntarily to the rhythm of the music. If the lead singer drives the audience's mental positivity, then the bassist should drive the audience's physical positivity. Keyboard player: Many bands feel that keyboard players are redundant, especially in some so-called rock bands. It is even rare to see keyboard players in heavy metal bands. They seem to think that if the keyboard is involved in the music, it's not "heavy" enough. The keyboard is the master of creating the atmosphere of the band. It does not mean that you can play piano accompaniment, but you can also lay the foundation with string strings. The great thing about the keyboard is that it cuts in and out, providing a certain amount of stimulation in a few small places, so that the music can shine. If the guitarist is not available, the keyboardist will be responsible for the melody. All in all, this is a very flattering and "hateful" position. Drummer: What kind of instrument is a drum? Rhythm instruments do not participate in the melody, but drummers should be the ones with the strongest sense of melody. They can use drums, a non-tonal instrument, to match the melody of the music. When it needs to be explosive, let it explode, and when it needs to be soft, let it explode. Calm, this is an amazing musical feeling. The drummer and bassist of most bands make up the cutout parts of their music. The reason why foreign bands are awesome is that their cutouts are so well arranged that the music always has a sense of jump and doesn't make people feel boring. . Another thing to say is that if the drummer can only play the drums and not play one or two other melodic instruments, it will not be of any help to the band's arrangement and rehearsal, and it will be a drag on the band.
