Phonetic Rhythm & Custom Alignment Sandbox
Scientific Context: Languages vary dramatically in prosodic cadence. English is stress-timed (equal time between stressed beats), whereas Korean & Spanish are syllable-timed, and Japanese is mora-timed. When adapting songs across languages, lyricists adjust pitch contours and syllable subdivisions to match musical meter without breaking linguistic naturalness.
