General Discussion / Re: Writing a Symphony
As for the "third overtone octaves are sharp, fifth overtone - flat" bit: It could be argued that according to just temperament. all octaves above the equal temperament fifth (i.e. E, or the third "overtone", assuming the piano is tuned to A440) are slightly flat, and all octaves above the third (C# or fifth overtone) are noticebly sharp! Brass and string players probably would (and would complain that the accompanying piano is out of tune, especially in flat keys).
