Editing Schenkerian analysis (section)

===First-order neighbor note===
Schenker stresses that the head note of the fundamental line often is decorated by a neighbor note "of the first order", which must be an upper neighbor because "the lower neighboring note would give the impression of the interruption". The neighbor note of the first order is {{music|scale|3}}–{{music|scale|4}}–{{music|scale|3}} or {{music|scale|5}}–{{music|scale|6}}–{{music|scale|5}}: the harmony supporting it often is the IVth or VIth degree, which may give rise to a section of the work at the subdominant.<ref>''Free Composition'', §106.</ref>
