For Worship Leaders

From idea to Sunday morning — faster.

Harrington helps you take a hymn or original song and get it ready for your team: updated chords, refined lyrics, a bridge if needed, and a clean chart out the door.

The weekly problem

Most weeks, you don't have time to fight your charts. You need to take a song — a classic hymn, a recent release, or something original — and make it work for your church. The chords might be outdated. The flow might not build the way you want. The team might need a bridge you haven't written yet.

Harrington is the workbench for that problem.

A typical workflow

Using "Be Thou My Vision" as an example:

  1. Load the song — import from a plain text, ChordPro, or OnSong file, or type it in directly. Sections are structured automatically.
  2. Update the chords — add modern voicings: G/B, Cadd9, D/F#, Em7. Chord lines stay aligned with lyrics as you type.
  3. Refine a line — ask Harrington for suggestions on any line that feels weak. You'll get three options; pick one and adjust it to your voice.
  4. Add a bridge — type the lyrics directly, or use AI to explore options. You stay in control of what goes in.
  5. Set the flow — arrange the order in the flow strip: V1 → V2 → B → B → V3 → B → B → B → V4. The chart will export in this exact order.
  6. Export once — ChordPro, ready to import into OnSong or Planning Center. No reformatting needed.

What Harrington does for worship prep

  • Import hymns and songs from plain text, ChordPro, or OnSong format
  • Chord editing with Nashville number and chord symbol modes
  • AI suggestions for lines — three options, you choose
  • Flow arrangement strip — drag tokens to set playback order
  • Song form templates (Verse-Chorus, AABA, and more)
  • Export to ChordPro, PDF lead sheet, DOCX, and plain text
  • Nashville numbers or chord symbols at export — your preference
  • Song Coach — ask questions about structure, thematic consistency, or "does this bridge work?"
ChordPro export is first-class. Harrington exports character-exact chord alignment, proper section directives, and flow-resolved arrangement. The result imports cleanly into OnSong with no formatting cleanup.

The authorship question

Harrington never writes songs for you. When you ask for suggestions, you get options — not rewrites. You pick what fits and adjust it until it sounds like you. The AI helps you think; you decide what belongs.

This matters for worship in particular. The song your congregation sings should come from your pastoral judgment, not a language model.
