A chord is 1 block of text without whitespace that must at least have a root, in this format:
<root>[alteration][suffix][/bass][alteration]
Example:
Gbmaj7#5/Bb
- Root: A name of a note. An uppercase letter between A-G. Required for any chord. E.g.
C - Alteration: An accidental (sharp/flat), may optional come after a note (root/bass). E.g.
#,b,##bb - Suffix: Anything related to the type of the chord and/or tensions. E.g.
m,maj7,7#9,b9b13,9,13 - Bass: Same as note, but must have a slash (/) before it and must come after a root (+ optional alteration and/or suffix ). No whitespace is allowed before or after the slash. E.g
/G
A bar consists of multiple chords separated by whitespace, following a barline. Optionally, a bar can start with a forward repeat barline. It could also be a repeat bar, also followed by a bar line. Optionally, a rehearsal mark, time signature or key signature can be added at the beginning. If they are added, the order matters, they must appear in the following order: Rehearsal Mark, Forward Repeat Barline Key Signature, Time Signature.

Chords occupy an equal of time in a bar if possible to fit into simple rhythms such as whole/half/quarter notes. If not possible, the later chords' rhythm is split to make them shorter. Examples:
Cmaj || -> 1 whole note
Cmaj7 Fmaj7 || -> 2 half notes
Cmaj7 G/B Am7 || -> 1 half note and 2 quarter notes
Cmaj7 G/B Am7 Am/G || -> 4 quarter notes
Cmaj7 G/B C/Bb Am7 Am/G || -> 3 quarter notes and 2 eighth notes
Cmaj7 G/B Am7 Am/G Fmaj7 C/E || -> 2 quarter notes and 4 eighth notes
To indicate rhythm more precisely you can use slashes /. A slash is a placeholder for a chord in the rhythm, without an acutal chord change. Make sure to have a space before and after, to avoid confusion with bass notes (i.e. C / B | is not the same as C/B |). Examples:
Cmaj7 / / Fmaj7 || -> The first chord has a duration of3 quraters, and the last just 1 quarter
Cmaj7 / Dm7 G7 || -> 1 half note and 2 quarter notes
Cmaj7 Dm7 C/E / || -> 2 quarter notes and 1 half note\
Can be added at the beginning of a bar with with the following syntax: NUMBER/NUMBER. Examples:
3/4 C | F | G | 4/4 Am G | F | 5/8 Dm | E / / E7 / ||
Can be added at the beginning of a bar with with the following syntax: [TEXT]. Examples:
[A] C | F | G |
[B] Am G | F |
[Outro] Dm | E E7 ||
Put the amount of # or b of the signature a t the beginning of the bar. Examples:
# G | C | D |
## D G | A |
bbb Cm | Fm G7 ||
- The current algorithm attempts to distribute chords equally in a bar, and if it can't it splits the duration of the later chords of the bar. This is a decent default for most use cases of pop/rock/jazz, imho. This doesn't work perfectly in all cases especially in odd time signatures (i.e. 5/8, 7/8), or mismatching number of chords in bar (i.e. 2 chords in a 3/8 bar). To avoid problems, I suggest to be explicit about the rhythm using slashes (
/) in those cases (i.e.Cmaj / G7). - x/2 or cut-time time signatures are not currently supported.
A line consists of multiple bars separated by barlines, and ending with a barline.

A sheet consists of multiple lines separated by a newline (\n). Example at the top (quick start section).
At the top of the file add the title and author seperated by a dash -. The title and author themselves cannot contain a dash. Separate the title and author from the rest of the sheet with 3 or more dashes (---) and a newline. Example:
Imagine - John Lennon
