Interval, in mufic. The diltance between any given 
found and another, ftriftly fpeaking, is neither meafpred 
by any common ftandard of extenfion nor duration ; but 
either by immediate fenfation, or by computing the dif¬ 
ference between the numbers of vibrations produced by 
two or more fonorous bodies, in the aft of founding, dur¬ 
ing the fame given time. As the vibrations are flower and 
fewer during the fame inftant, for example, the found is 
proportionally lower or graver ; on the contrary, as dur¬ 
ing the fame period the vibrations increafe in number and 
velocity, the founds are proportionably higher or more 
acute. An interval in mufic, therefore, is proped/ the 
difference between the number of vibrations produced by 
one fonorous body of a certain magnitude and texture, 
and of thofe produced by another of a different magni¬ 
tude and texture in the fame time. Intervals are divided 
into confonant and diffonant. A confon mt interval is 
that whofe extremes, or whofe.highefl and loweft founds, 
when fimultaneoufly heard, coalefce in the ear, and pro¬ 
duce an agreeable fenfation called by lord Karnes a tertium 
quid. A diffonant interval, on the contrary, is that whole 
extremes, fimultaneoufly heard, far from coalefcing in 
the ear, and producing jpne agreeable fenfation, are each 
of them plainly difififiguilhed from the other, produce a 
grating effeft upon the fenfe, and repel each other with 
an irr.e.co.ncileable hoftility. In propotion as the vibra¬ 
tions of different fonorous bodies, or of the fame fonorous 
body in different modes, more or lefs frequently coincide 
during the fame given time, the chords are more or lefs 
confopant.
