But with all these often opposed conditions, we find less variation than might be expected, the main and really important divergence being due to the necessity of transposition, which added a very high pitch to the primarily convenient low one.
The larger high-pitch organ will therefore be at a' 502.6.
In one passage he distinctly says the old organ high pitch had been a whole tone above his Cammerton, with which we shall find his tertia minore combines to make the required interval.

The high pitch remains only where there are large concert organs not yet lowered, and with the military and brass bands.
