[3] It has also been argued that the same phenomenon is heard in English sentences, if these sentences are pronounced with a falling intonation, for example I really believe Ebenezer was a dealer in magnesium, or I bought blueberries, bayberries, raspberries, mulberries, and brambleberries.
When two high tones are in succeeding syllables (thus in the sequence H H), and the second is lower than the first, there is said to be a downstep.
[8] The symbol for the second kind of downstep in the International Phonetic Alphabet is a superscript down arrow, ⟨ꜜ⟩ (↓).
because of typographic constraints, though technically that would mean an incompletely or lightly articulated alveolar click release.
It has been shown that in most, if not all, cases of downstep proper, the lowering of the second high tone occurs when an intervening low-toned syllable has dropped out.
