Weeks 7-8 · voice · connected phrase
Two syllables, one shape. Don’t let silence sneak in.
The rule
pass: no silent gap > 80 ms · 5/5
Amplitude over time, two syllables. The top emerald envelope barely dips between “la” and “la” — the voice stays on through the consonant. That’s legato; that’s pass. The bottom grey trace shows the failure mode: the envelope returns to baseline between syllables, producing an audible silent gap larger than the 80 ms ceiling.
Hear it first
First clip: “la-la” sung as one connected gesture — you barely hear the second “l” as separate from the first. Second clip: the same two syllables but with a beat of silence inserted between them. That gap is what we’re measuring against.
What’s happening.Legato is the singer’s default mode: phrases flow through their consonants, they don’t break around them. The vocal cords stay vibrating across the “l” of la-la; the airflow doesn’t stop, the larynx doesn’t reset. Beginners instinctively re-attack each syllable as if it were the start of a new note, which produces a measurable silent gap of 100–300 ms — enough that the listener hears two words instead of one shape.
Why an 80 ms ceiling.A voiced consonant (like “l” or “m”) takes about 40–60 ms to articulate cleanly. Anything under 80ms reads to the ear as “same phrase, two syllables”; anything above it reads as a separation. That’s the natural perceptual line we’re training to.
Why this is the bridge to lyric. Every word of every song is more than one syllable. If you can’t connect two syllables here without a gap, breath-grouping-phrase and verse-breath-plan downstream will fragment every line. This is the first lesson where you sing something that resembles a word.
