Final answer:
Unfortunately, the reference material provided does not contain information about the blind shamisen player born between 1614-1684 who mastered the Japanese koto, therefore we cannot accurately identify this historical figure. The reference details other artists from various periods, their contributions to Japanese culture, and their dedication to their respective art forms.
Step-by-step explanation:
The blind shamisen player born between 1614-1684 who mastered the Japanese koto and devoted his life to making it accessible to others is not explicitly named in the provided reference material, meaning an accurate response to the original question cannot be given based on the supplied information.
However, to provide context to the subject matter, the shamisen is a traditional Japanese string instrument pivotal in enhancing the mood in various Japanese art forms. The era in which the unidentified musician lived saw many artisans, such as Kano Eitoku, Utagawa Kuniyoshi, and Utagawa Hiroshige, contribute significantly to their respective fields, from painting and woodblock printing to music. Prominent figures in traditional Japanese art often had a profound influence on both their contemporaries and future generations, fostering cultural developments that resonated through time. Dedicating oneself to an art form, as the mysterious shamisen player did with the koto, symbolizes the deep dedication found in Japanese artistic traditions, leaving a lasting legacy that could influence music, visual arts, or even performance arts like Kabuki.
