In each Triad, the first six partials of the lowest tone, the first five of the middle tone, and the first four of the highest tone are given. The partials, that dissonate at the interval of a tone are connected, as before, by a single bine, those dissonating at a semitone distance, by a double line. Whenever any partial dissonates with two partials of the same pitch, the first partial is connected with that partial of the other two which is of a lower order, that is, with the one which is presumably the louder of the two.
In order to facilitate the comparison of the Triads, an analysis of fig. 85 is given in the following table, in which the first horizontal line gives the names of the Triads ; the next three lines show the
