Note 7 — Art. I. Essay on Musical Temperament.
Reading edition
The propriety of this limitation will be manifest, when we consider that in organ music, the chords are generally played more full, and are more protracted, than in music for other keyed instruments. It is harmony which constitutes its character, in a higher degree than in music for other instruments. Hence the harmony of the organ ought not to be impaired by including in our computations any music not adapted to it. If a similar examination of music for the piano-forte would afford a set of results essentially different from those of this proposition, this is no proof that it ought to have any concern in a system of temperament designed primarily for the organ, but merely that the same temperament cannot be equally adapted to different instruments. If, as is probable, such an examination would give essentially the same results, to introduce them would be superfluous.
