in the annals of musical instruments' evolution, there existed a clandestine movement known as sub rosa, where musicians, weary of the preestablished norms that dictated the symphonies of their time, began to tune out the cacophony of expectations. in the shadows, these avant-garde artists dared to experiment with unconventional sounds and techniques, seeking to recommence with a new vision for what music could be. their sub rosa gatherings were not merely secret meetings; they were crucibles of innovation, giving birth to a new era of musical exploration that, unbeknownst to many, would shape the soundscapes of future generations.
