Well, Carnegie Hall is located at the corner of 57th Street and Seventh
Avenue in Manhattan. Buses M5, M6, M7, M30, M57, and M104 stop nearby
according to the information from the Source. Now, if you tell me that
you meant something else, that's OK, I know: you can also take the Subway.
Or a taxi. They know how to get there, since they practice all their lives.
Or, you can also read this paper by Robert Filman:

I am not sure what Filman wanted to say, but at the beginning of this paper
you will find (phrased differently) the "AHA!" moment: "Everything I know
is wrong!".
