When two notes are not quite in tune, you hear beats, and that sounds terrible, musically. The beat rate is half the difference in frequency between the two notes. For a 1-second note (whole note in a cut-time march), at C7 (using Dan's table), you would have to be within 2 cents to prevent a beat. At a more realistic note, C6, that's a bit less than 4 cents. But at E3, that's about 27 cents off.
That's a good reason not to put 2 high-pitch instruments in unison on a long note.
But to minimize the problem, I would want the instruments in tune as well as possible on the HIGH notes.
