It can be assumed that a person from the late 1800s, prior to the advent of metal music, would likely have a vastly different musical taste and expectation compared to contemporary individuals. The musical landscape in the late 1800s was dominated by classical music, folk music, and religious hymns, with the occasional inclusion of ragtime and blues.
The introduction of metal music, characterized by its aggressive musical style, powerful instrumentation, and distorted guitar sounds, would likely have been a shock to the musical sensibility of a person from the late 1800s. The musical elements present in metal music such as amplified sound, fast tempos, and complex musical structures, would have been entirely foreign to their musical experience.
However, it is also important to note that musical preferences are subjective and can vary greatly from person to person. Some individuals from the late 1800s may have been open to new musical experiences and may have appreciated the energy and power present in metal music. On the other hand, others may have found it to be cacophonous and overwhelming.
In the absence of lyrics, it is possible that a person from the late 1800s may have been able to appreciate the musicality of metal music to some extent. The musical elements present in metal music such as intricate guitar solos, synchronized drumming patterns, and dynamic changes in tempo and volume, could have been seen as impressive displays of musical skill.
However, it is also worth considering that metal music's association with countercultural and rebellious movements may have made it less appealing to a person from the late 1800s, who would have likely held more conservative social and cultural values.
In conclusion, it is impossible to determine with certainty how a person from the late 1800s would have reacted to metal music sans lyrics. The reaction would have likely been influenced by individual musical preferences, exposure to new musical experiences, and cultural and social values.
