The values given in the first column are those of the ideal 
intervals, such as are secured by using pure intonation ; 
those given in the second column are those of equally tem- 
pered intonation, such as is used on keyed instruments, like 
the pianoforte and the organ. (See intonation^ and tem- 
perament. ) A diatonic interval is one that occurs between 
two tones of a normal major or minor scale. A chromatic 
interval is one that occurs between a tone of such a scale 
and a tone foreign to that scale. An enharmonic interval 
is one on an instrument of fixed intonation, that is ap- 
parent only in the notation, being in fact a unison, as, on 
the pianoforte, the Interval from FJ to Qfe. In musical 
science the theory of intervals is introductory to that of 
chords and to harmony in general.
