txtCommentary1=At the highest structural level within the {\uldb \'93Dissonant\'94 Quartet}{\v 210983}, Mozart uses {\uldb modulation}{\v 88241} (changes of {\uldb key}{\v 85386}) to create the greatest degree of tension and {\uldb resolution}{\v 94075}. The most dramatic instance occurs in the {\uldb development}{\v 79173} of this same {\uldb finale}{\v 82354}. Within the space of less than twenty seconds, Mozart traverses no fewer than five keys. Isolating the {\uldb tonic chords}{\v 101048} of these five keys shows how
txtCommentary2=distantly related they are (for theory buffs: E-{\uldb flat}{\v 82547} {\uldb major}{\v 86320}, F {\uldb minor}{\v 88035}, E minor, F-{\uldb sharp}{\v 96408} minor, and G-sharp minor).\par\par\par\par As a full {\uldb passage}{\v 90954}, the result is only slightly less\par jarring.{\fs24\uldb \'80}{\v next}
