Spanish Syllable Checker — Real Silabeo for Spanish Lyrics

• Paste your Spanish lyrics — one line per row — and hit Divide syllables. Each word is split with real Spanish division rules, joined by dots: co·ra·zón, gui·ta·rra, bai·la.
• The underlined syllable is the stressed one — from written accents (canción) or the standard stress rules (ca·mi·nan·do).
• The per-line count is what you sing to. Spanish counts syllables the way they’re pronounced — aire is two, canción is two — and this tool applies those rules instead of guessing from letter count.

Spanish is a syllable-timed language with clean, consistent division rules — which means a Spanish lyric either fits the melody syllable-for-syllable, or it doesn’t, and listeners hear the mismatch instantly. English writers can cheat by swallowing a vowel; Spanish mostly can’t.

Two rules trip up non-native writers constantly: diphthongs (bue·no is two syllables, not three — u and e fuse) and hiatos (pa·ís is three, not two — the accented í refuses to fuse). And where the stress falls decides whether your line rides the beat or fights it. This tool applies all three so you can see the mechanics of every line.

• Match the stressed syllables to the strong beats. If canción lands its stress on “cán” instead of “zón”, the line fights the melody — swap the word order or pick a synonym.
• Sinalefa is your friend. When one word ends in a vowel and the next begins with one (sobre_el_mar), singers fuse them into one sung syllable. The tool counts written syllables; subtract one per fusion when you count against a melody.
• Then regenerate: once the mechanics are clean, draft full lines with our Spanish lyric generators — they keep phrasing native from the first word.
