Tuning is actually the next stage of composing and a transition from composing to performing.
The regulator comes to arrange the work, or if the performance is electronic, it comes to the sounds and determines the type of arrangement.
The arranger also takes on the role of performing the work, which was once in the hands of the conductor.
Of course, the role of composer and arranger is different depending on the style, whether it is acoustic or electronic in general? Be it pop or orchestral or rock or even traditional. Rules can change in any of these styles.
For example, in orchestral music, the composer performs part of the task of arranging and the conductor performs part of the task.
But in pop or electronic music, there is another definition of regulation, which includes the processing of sounds and the intensity and penning (position of sounds). (Among other things
How do we know what part of a piece of music belongs to the composer and what part belongs to the arranger?
First of all, you have to be a professional listener of music. But we give you a comfortable criterion, if you hear the voice of a singer who is singing a song, the melody and tone of this song is the work of the composer.
But if what you hear is about the combination of different sounds and instruments and their intensity, as well as the rhythm, it is probably the work of a tuner.
Of course, you can not say for sure that the role of composer and arranger can be completely separated, but the composer’s job is mostly to create the components of the song and the job of the arranger is how to combine, sound and engineer the sound.
