Intervals from the dominant triad, very common in melodic writing, are the same as those from the tonic triad, but in a different context. In major keys, syllable names for members of the V triad are sol-ti-re (ascending), and the scale degree numbers are 5-7-2, as at a and b below. Observe also that c, its members can be identified as R-3-5 of the triad.
