I am looking for a short story whose main character was loosely based on Alan Turing. In the story he was looking for a way to visualize multi-dimensions and casually meets his neighbor, a young Asian boy who is a musician who says he can "see" other dimensional objects and describes directions using words like "reft" and "dup". Eventually, they have an encounter with multi-dimensional beings which are attracted to the boy's music and he is abducted. I believe it was published in a magazine but I think I read it in "Year's Best SciFi" in the eighties or nineties. Who was the author and what was the name of the story? Thank you.
This is probably "Tangents" by Greg Bear:
This story was written by Greg Bear, and was first published in Omni in January 1986. Pal Tremont, a Korean boy who likes classical music, is adopted by an American family and comes into the life of Peter Tuthy and writer Lauren Davies. Peter is a mathematician and computer hacker (seemingly based in part on Alan Turing) who is very interested in 4-dimensional space (4-D). Lauren wants Pal to help her with her writings, but Pal is more useful to Peter as he can easily visualize 4-D space. Pal is able to see a whole new world, inhabited by 4-D beings and is even able to play 4-D music for them. The beings eventually make contact and take Pal and Peter into their own world.
According to ISFDB, it won a few "best" awards, including a 1987 Hugo, a 1987 Nebula, and a 1994 Seiun and was included in a few "Best of" collections including Nebula Awards 22: SFWA's Choices for the Best Science Fiction & Fantasy 1986.
