Thus, in both the cases under consideration, each beat will be Mr. S.

In order to as-certain what happens at intermediatepoints of time, we have only to deter-mine the resultant curve for a suffi-cient number of wave-lengths. This isdone in fig. 5, which is constructedfor the interval of a semitone (16 : 15),and represents completely the state ofthings from a maximum of intensityto the adjacent minimum. The highertone is taken as the louder of the wave-lengths here gradually di-minish as we advance from the maxi-mum to the minimum of intensity ;and, accordingly, the pitch of the va-rying tone rises continuously, passingthrough every gradation which sepa-rates its gravest va
