Description:
text2beep 0.1.0
text2beep
Language: 中文 | English
text2beep is a CLI tool that converts plaintext sheet music (currently only supporting JSON format) into beeps and play them.
The tool is still in its early development with only such basic features as synthesizing and playing. More features will be added in the future.
Installation
There hasn't been any releases yet. Please wait patiently for the first release. If you want to get notified when the first release is available, you may click "Watch -> Releases Only" at the top right corner of the page.
Before the first release, you may install by typing:
pip install git+https://github.com/shniubobo/text2beep.git#egg=text2beep
Usage
text2beep is easy to use. Simply prepare your sheet, then type:
text2beep /path/to/your/sheet.json
and the program will start to read the sheet, and synthesize and play music according to it.
There are several example sheet files present in the examples directory. You may try them out before creating your own sheets.
For a complete option list of the tool, type text2beep -h.
Creating your own sheets
Currently only JSON sheets are supported. More formats may be supported in the future.
Structure of a sheet file
{
"bpm": 120,
"time_signature": "4/4",
"tracks": [
[
"E4--- C4--- D4--- G3---"
],
[
"C4--- A3--- B3--- E3---"
],
[
"A3--- F3--- G3--- C3---"
],
[
"A2--- F2--- G2--- C2---"
]
]
}
where BPM (bpm) and time signature (time_signature) are used to determine the playing speed of the song, and tracks are all the tracks of the song.
If you want to split a sheet file into several parts, or specify different BPM and time signatures for different parts of your music, you can achieve these with subsheets:
{
"subsheets": [
{
"bpm": 120,
"time_signature": "4/4",
"tracks": [
[
"E4--- C4---"
],
[
"C4--- A3---"
],
[
"A3--- F3---"
],
[
"A2--- F2---"
]
]
},
{
"bpm": 120,
"time_signature": "2/4",
"tracks": [
[
"D4--- G3---"
],
[
"B3--- E3---"
],
[
"G3--- C3---"
],
[
"G2--- C2---"
]
]
}
]
}
All subsheets will be played one by one, or you can specify the playing range with the --range option (see text2beep -h for details).
Syntax of tracks
Each track is a list (as is called in Python) or an array (as is called in JSON). All strings within the list are concatenated into a single one by the tool during runtime. Although you can put all the notes into one string, it is recommended to divide them into several ones to improve readability.
Spaces and | can be added arbitrarily to improve readability. They will be completely ignored by the program.
Notes in a track are played one by one. All tracks are played simultaneously.
Syntax of notes in the tracks:
The note name must be one of CDEFGABX, where X stands for rest notes.
If a note is not a rest note, an accidental b or # may be appended to it.
If a note is not a rest note, an octave from 0 to 8 needs to be specified.
Name first, accidental second, octave third. For example: C#4.
A note is a quarter note by default. For example, C4 is a quarter note.
Each - extends the note value by 0.25. For example, C4- is a half note.
Any number of - may be used. For example, C4--- is a whole note, while C4-- is equal to C4-+C4 (See below for +), although in this case the meaning of a dotted note (C4--.) is ambiguous, and thus the usage of two or more than three - is not recommended. In other words, use only - and ---.
Each / shortens the note value by half. For example, C4/ is an eighth note.
Notes can be dotted with .. For example, C4. is a dotted quarter note.
- and / cannot be present in the same note.
+ can be used as a tie between notes (not a slur!).
