The answering phrase mirrors the head downwards and returns to the note the tune started on. The melody keeps moving -- roughly two to three notes per second, not long held chords -- so that a listener could hum it back after one hearing. a four-note head that is recognisable within its first few notes; regular harmonic rhythm, one chord per bar, so the grid never moves while the harmony under it does; sentence form: basic idea, basic idea, continuation, cadence, in 2+2+4 bars; the continuation by fragmentation of the opening cell, not by new material; the loop ends open rather than landing finally. Mood: heroic, contemplative, hopeful, warm. Fully instrumental, no voices, no singing, no lyrics. No drum kit, no synthesizer, no electric guitar, no modern pop production.

The melody is the point and must be in the clear foreground throughout: one line, one note at a time, played legato by the solo carrier, with the accompaniment quiet underneath it. The head motif is exactly four notes. The first three rise through the notes of the tonic triad -- the key note, then the third above it, then the fifth above that. The fourth note LEAPS UP by a major sixth from that fifth and is held. That upward leap of a sixth is the one striking interval in the piece and it must actually be there; every other interval in the tune is a step or a small skip of no more than a fourth. The answering phrase mirrors the head downwards and returns to the note the tune started on. The melody keeps moving -- roughly two to three notes per second, not long held chords -- so that a listener could hum it back after one hearing. a four-note head that is recognisable within its first few notes; regular harmonic rhythm, one chord per bar, so the grid never moves while the harmony under it does; sentence form: basic idea, basic idea, continuation, cadence, in 2+2+4 bars; the continuation by fragmentation of the opening cell, not by new material; the loop ends open rather than landing finally. Mood: heroic, contemplative, hopeful, warm. Fully instrumental, no voices, no singing, no lyrics. No drum kit, no synthesizer, no electric guitar, no modern pop production. Clean start and clean end with no fade in and no fade out.",
