The OpenPsalm Style Guide

By Jon Hood 2026-07-07

Every score in the catalog follows one house style. Here's what the markings mean, with examples.

Beams follow the words

Notes are beamed together only when they share one syllable. If each note has its own syllable, the notes are flagged separately.

Beamed = one syllable. Flagged = a syllable on each note.

Longer runs get a slur

A run of notes on one syllable is a melisma. When the run includes a quarter note or longer, a beam can't cover it. A slur spans the whole group instead.

A slur spanning a quarter note, two beamed eighth notes, and another quarter note, all sung on the syllable 'sing' — All four notes under the slur are sung on “sing.”

Tie, slur, or nothing?

A tie joins two notes of the same pitch into one held sound. A slur joins different pitches on one syllable. Repeated pitches with no arc get a fresh syllable each.

Three measures labeled tie, slur, and no arc: a tie holds one pitch through both notes, a slur carries one syllable across two pitches, and unmarked repeated notes each take their own syllable — Tie: hold through. Slur: one syllable, new pitch. No arc: sing each note.

The dashed slur

Sometimes the verses disagree: one verse puts a syllable on each note of a pair, another sings through them on one. A dashed slur means check your verse: if your verse has a syllable under each note, sing them separately; if it shows a gap, carry your syllable through.

A dashed slur over two eighth notes with two verses of lyrics: verse one has a syllable on each note, verse two leaves the second note's slot empty and melismas through — Verse 1 sings both notes (“ho-ly”); verse 2 carries “glo” through the pair.

The page stays simple

A few more rules keep the page easy to sight-read. Every measure is complete—a pickup sits at the end of a full first measure. Repeats are written out in full, so there are no repeat signs or endings to navigate mid-song. Line breaks follow the poetry. And in the standard SATB layout, markings that apply to everyone print once: dynamics above the top staff, fermatas once per staff, tempo changes (rit., a tempo) above the score.

These are similar to the conventions of traditional vocal engraving—the kind you'd find in a well-set hymnal from a century ago. A congregation sight-reads in real time, so every marking has to answer a question before the singer asks it. A page that answers quietly gets out of the way of worship.
