ChordPro + LRC Format Guide

SynchroPlay combines the industry-standard ChordPro notation format for chords with LRC timecodes for millisecond-precise audio scrolling and band synchronization.

1. The Hybrid Syntax (Timecode + Chords + Lyrics)

Place the LRC time tag [mm:ss.xx] at the start of any line to sync it with playback. Chords are placed inside brackets [Chord] directly ahead of the lyric syllable:

{title: Stand by Me}
{artist: Ben E. King}
{key: A}
{time: 4/4}

[00:15.50] {start_of_verse: Verse 1}
[00:17.20] When the [A]night has come
[00:21.00] And the [F#m]land is dark
[00:25.50] And the [D]moon is the [E]only light we'll [A]see
[00:32.00] {end_of_verse}

2. Supported Directives

{title: ...} or {t: ...}

Sets the song title displayed in the header.

{artist: ...} or {a: ...}

Sets the artist name.

{key: ...}

Displays the key badge in the performance toolbar (e.g., {key: Em}).

{time: ...}

Displays the time signature badge (e.g., {time: 4/4} or {time: 6/8}).

{comment: ...} or {c: ...}

Renders performance remarks or playing instructions in italics on stage.

3. Structural Sections & Color Coding

Section tags apply distinct accent borders and header pills during live performance. You can optionally include a custom label after a colon (e.g., {start_of_verse: Soft Verse}):

{start_of_verse} / {end_of_verse}

{start_of_chorus} / {end_of_chorus}

{start_of_bridge} / {end_of_bridge}

{start_of_prechorus} / {end_of_prechorus}

{start_of_intro} / {end_of_intro}

{start_of_instrumental} / {end_of_instrumental}

4. Bar / Grid Notation

For instrumental solos, intros, and chord charts without lyrics, use grid blocks with pipe | delimiters:

[00:05.00] {start_of_grid: Intro Solo}
[00:07.00] | Am . . . | F . . . | C . . . | G . . . |
[00:15.00] {end_of_grid}
