Charles K. Harris, "Climb a tree with me" (1912). It might not seem very promising to begin a song on climbing with an octave's worth of descending tonic-chord arpeggio, but there is a clue in the answering phrase, "As we climbed long years ago." The lower ^5, as Eb4, goes up to a firmly held ^6, and "all the birds sang" with ^7 suggests going further. In the end, the proto-background interval of the octave (shown with the unfolding in bars 1-4 and again later) maintains Eb5 while its lower element Eb4 closes to Ab4. This is not a wedge--Eb5 stays put and the principal line is the one that proceeds from Eb4.
