Note the rhythmic displacement

rhythmic displacement using different improvisationalstrategies, such as phrase displacement, metric displacement, manipulation of phraseaccents, and melodic interpolations. Phrase displacement occurs when the phrase is shiftedby a beat (or more) and creates a dissonance with the underlying harmonic and metricstructure. Probably the most effective use of this technique occurs in m. 77 where theline begins on beat 2 with a downward arpeggiation of the E major upper-structure triadover the structural B≤7 and is further emphasized with a strong accent on the first quarternote, EΩ4. The manipulation of phrase accents shifts regular metrical accents, therebycreating metric ambiguity. This technique occurs when the phrase temporarily rendersbeats 2 and 4 as beats 1 and 3. The phrase in mm. 159–160 illustrates these features.Notice how beat 4 in m. 159 influences the perception of beat 2 in the next measure.Metric displacement implies the use of cross rhythm to create a characteristic rhythmic joltand increase in tension within the phrase. The phrase in mm. 81–83 displays thesecharacteristics. The distribution of accents and phrase groupings in mm. 81–83 createsan interesting superimposition of 3/4, 3/8, 2/4, and 4/4 respectively. Notice how theuse of 3/8 influences the metric location of sub-phrases in 2/4 and 4/4 in mm. 82–83,and how the perception of the meter in the ensuing measures is constantly beingchallenged
