I have been testing intonation for euphonium manufacturers since around 1980, and it soon became clear to me that there are many possible ways to get inaccurate results. Is the horn warmed up fully? Am I playing the horn's Ab or I am playing the way I always play an Ab on a different horn? Am I unconsciously bending the pitch to make it look better than the horn really plays because I favor the horn? Etc.
Whenever I ran these tests I wanted the results to represent what the horn actually
