Also Isolates retrograde of frame for second figure in section c through frame for the first figure of Structural tone emphasis sustained in the trombone opening cadenza flourish Isolates frame for first figure in the opening cadenza flourish (last chord) articulation markings the opening cadenza Projects single embellished main chord built on the structural common tone B¯4 and its pitch-space inverse simultaneously. This is the harmonic content of section A of the opening cadenza embellished by its pitch- space inverse. Projects embellished main chord built below G5 anchor Background note B4 Projects first chord of note and other notes of the Harmonic structure sustained in the trombone Projects second, third and fourth chord of Don Don Projects embellishment of opening chord of Don frame for section c.
