 However the frets may be removed entirely—this, unfortunately, makes in-tune fingering of many chords exceedingly difficult, due to the construction and mechanics of the human hand—and the tuning of most complex chords in just intonation is generally ambiguous.Some composers deliberately use these wolf intervals and other dissonant intervals as a way to expand the tone color palette of a piece of music.For example, the extended piano pieces "The Well-Tuned Piano" by LaMonte Young and "The Harp Of New Albion" by Terry Riley use a combination of very consonant and dissonant intervals for musical effect.
