===Example===
The modal frame of [[The Beatles]]' "[[A Hard Day's Night (song)|A Hard Day's Night]]" features a ladder of thirds axially centered on G with a ceiling note of B{{music|flat}} and floor note of E[{{music|flat}}] (the low C being a [[passing tone]]):<ref name="Middleton"/>

According to [[Richard Middleton (musicologist)|Middleton]], the song, "at first glance major-key-with-modal-touches", reveals through its "Line of Latent Mode" "a deep kinship with typical [[blues]] melodic structures: it is centred on three of the notes of the minor-[[pentatonic scale|pentatonic]] mode [on C: C, E-flat, F, G, B-flat] (E{{music|flat}}-G-B{{music|flat}}), with the contradictory major seventh (B{{music|natural}}) set against that. Moreover, the ''shape'' assumed by these notes – the modal ''frame'' – as well as the abstract scale they represent, is revealed, too; and this – an initial, repeated circling round the dominant (G), with an excursion to its minor third (B{{music|flat}}), 'answered' by a fall to the 'symmetrical' minor third of the tonic (E{{music|flat}}) – is a common pattern in blues."<ref>Middleton (1990), p. 201.</ref>
