The augmented 5th interval below F# is Bb The diminished 5th interval below Fb is Bb B-flat 5th inverted intervals Shortĥth intervals below note B-flat Intervals below Short This table inverts the above intervals, so that each link in the last column leads to note B-flat. Inverted intervals identifying note B-flat These intervals are shown below on the treble clef followed by the bass clef. Middle C (midi note 60) is shown with an orange line under the 2nd note on the piano diagram. 5th intervals above note B-flat B-flat dim5-perf5-aug5 intervals Short This gives a strong indication of a V-I cadence in itself, even in the absence of the A naturals helping to outline an F chord (or provide the obviously raised seventh scale degree).This step shows the B-flat fifth intervals on the piano, treble clef and bass clef. Notice the emphasis placed on C in the two measures preceding the F, particularly the two immediately preceding it. However, consider a passage in which there are no A naturals. In this passage, the approach listed above is clearly more complicated, and unnecessary. Singing or humming the passage, if possible, provides a final confirmation.īut why bother, since the first approach is so simple.Working back another measure, C and Eb are emphasized, further reinforcing dominant harmony: F - A - C - Eb.The second hint is the measure before, which emphasizes A and C - combined with F, this clearly outlines F major, the dominant of Bb minor.This could be the third of a Db major harmony or the root of an F chord, the dominant of Bb minor. The first hint is that the passage ends on F.In addition to the presence of A-natural, well explained in other posts, there is a second clue, but not as immediately evident.
