On the Sensations of
Tone
Hence he concludes that with c" — 8 ; nor does it form the sound 9 with the
summational tone, if not existing as a the Octave of e,' or e," = 10, as we can be
con- partial on one of the tones, is entirely gene- vinced by sounding at the same
time ...

Introduction to the Psychology of Music
The first is called a differential, the second a summational tone. The vibration
number of the d'flerential tone is equal to the diflerenee between those qf the
generating sounds ; that of the summational tone is equal to the rum of those of
the ...

On the Sensations of
Tone as a Physiological Basis for the ...
Scarcely any but the first summational tone can be perceived, having a
vibrational number equal to the sum of those of the generators. Of course
summational tones may also arise from the harmonic upper partials. Since their
vibrational ...

The Physical Basis of Music
There is also a Summational Tone, whose frequency is the sum of the
frequencies of the two generators. This tone is much fainter than the Differential
Tone and was not discovered till much later. Both these tones are known as First
Order ...

Wrightson attributes to the (x+y) series the summational tone, and to the (x — y)
series the differential tone. The correlation is, however, unsatisfactory. It is to be
presumed — and Wrightson seems to imply — that similar properties in the ...

387) for demonstrating the summational tone on the piano does nothing of the
kind. The tone which sings and "may be heard by an audience of a hundred or
more" is not a, but a1, the octave of the strings freed from their damper. Naturally

He further calculated that there must be a second combination tone, which must
be higher than the two primary tones, to which he gave the name of summational
tone, because it results from the sum of their vibrations. He assumed that the ...
