What are the differences and connections between the loudness and timbre of the three elements of music? Does tone mean the level of voice?

Personally, I think loudness and timbre are slightly different, but not much. Loudness is closely related to sound equipment and human hearing. Too loud will make them feel disgusted, uncomfortable, too quiet and too weak. Therefore, it is necessary to combine the emotions in music to set up a feeling of highland ups and downs, and the timbre is different. All timbres can create different feelings. If you study music, I suggest buying a guitar to practice.

In fact, foreign brands are well known, so I will briefly talk about the better domestic guitar brands.

Enya Guitar: The appearance is very good, and the face value control can be started, but the timbre feels a little different.

Take the fire guitar for example: it is the same as Enya, but its face value is slightly worse than Enya's, but it has a strong sense of technology and its price is more expensive than Enya's.

Saga Guitar: Guitar of foreign brands is also made in China. It's more traditional and has no characteristics.

Venice Guitar: Domestic Guitar has a strong credibility. It is a cooperative brand of CCTV. Its advantage is that it feels good, which is very helpful for improvisation and music creation. However, few people know about brand promotion.
