The ostensible design of our invention is to produce harmony ; 
but even those who delight in discord, can find, in our instru-

pedal belonging, for instance, to the scale of E, and playing in 
the scale of Ab, they will be furnished with an amount of dis- 
cord, to which our common tempered instruments bear but a 
faint approximation. ‘'T'o express the effect, the ordinary term of 
“wolf” is weak. If this effect be too severe, any less amount of 
discord, or temperament, can be obtained by putting down a less 
remote modulation pedal. Discords have their appropriate place 
in music, but their place is no¢ in a common chord, or where the 
composer désigned a concord. In such combinations many love

scale in which the music is written.
