Technically, the 2021 summer film season started June 4 — technically ahead of summer months commences, even though very long soon after a summer time film year generally begins — with the launch of ecstatic “In the Heights,” as giddily outdated-fashioned a motion picture musical as you could hope for in 2021, with the obvious exception of hip-hop influences, unless you take into consideration patter tracks to be early (very white) precursors of rap.

Unusual interlude for theater lingo: A patter song is that light-hearted ditty characterized by quickly tempos and speedy-fire lyrics, typically whimsically rhyming, alliterative or tongue-twisting, and in a limited vocal array. Derived from comic opera.

Basic illustration: “I am the very product of a modern-day main general,” from Gilbert and Sullivan’s “The Pirates of Penzance.” Or for a 1970s instance, “Obtaining Married Nowadays,” from Sondheim’s “Company,” which at a single point blurts 68 words and phrases in 11 seconds. Frantic Amy spits out: “Wedding, what is actually a wedding day? It can be a prehistoric ritual the place/All people guarantees fidelity eternally, which is/Perhaps the most horrifying phrase I at any time read, and which is/Adopted by a honeymoon, in which suddenly he’ll notice he’s/Saddled with a nut and wanna eliminate me which he should.”
