What Are Adeste Fidelis Leaps?

Term coined by Robert O. Gjerdingen, after an observation by Leonard B. Meyer.

In the words of Gjerdingen, “in the 1970s, Leonard B. Meyer noticed that many eighteenth-century phrases resembled the opening of the hymn tune ‘Adeste Fidelis’. Its melody, believed to date from the early eighteenth century, opens with a variant of the Do-Re-Mi that features melodic leaps down to, and up from, ➎” (Gjerdingen (2007), p. 85).
