In improvisation, "to reverse" may mean inhibition: the spontaneous or planned prevention of a process. It can be a principle of artistic design that is intended to prevent certain mechanised or automated processes, which is intended to break linear sequences. It may be a guiding idea that prefers the fragment and the broken to the flowing, linear. Instead of entering during a silence, I can block the impulse and delay the entrance or do without. An impulsive dynamic fortissimo I can suddenly transform into its opposite, a very quiet, flat passage.
Related terms which have to do with the movement of the body or an object are: to reverse or to turn upside down. To turn a glove inside out, to turn from my back to my stomach, a type of movement, a figure of speech. In musical composition, one speaks of inversion or mirroring when the intervals of a sequence of notes are reversed on a mirror axis: a minor third up becomes a minor third down. Musical-compositional inversion is significant in the compositional method of the fugue, which was then taken up again by Arnold Schönberg in twelve-tone music, a strict method in which the direction of the musical theme is decisive for the composition - the inversion forms the counterpoint here, the negation in dialectical thinking (based on the equivalence of opposites) or the addition to a whole by the "other" half.
