A second worked experiment tests accent: the same eight notes played twice, once with the accent on every second beat, once displaced onto every third. The question: does the metre the listener hears follow the notation or the accent? The evidence (two recordings, listeners' taps) shows the perceived grouping following the accent: the verdict feeds the creator's next piece, where a notated four is heard as three until the accent returns.
Worked example, concluded. The texture experiment's rationale: a fixed melody isolates one variable (the added part) so the change can be heard alone. The commentary: take one, monophonic and exposed; take two, the same melody now sitting on a sustained tone, two-part, the E4 reinterpreted as part of a new harmony. Verdict: texture and harmony can move while melody stands still.

Boundary notes: the examiner must see the music happening: engagement shown in the elements, the processes evidenced, the work finished. All worked examples are original.
