Numusic is a text-based descriptive language for writing numbered musical notation. Details of its syntax can be found in overview.txt.
Its purpose currently is only to calculate the optimum assignment of the musical instrument Angklung in a group. An angklung can only produce a specific tone, thus it requires a lot of people to perform songs. A score written in this language can easily be converted into a list of players with their assigned instruments and play intervals, free from conflicts.
Simply run parse.py (optimized assignment) or plain_parse.py (normal assignment) with a score file.
python parse.py file/path
python simple_parse.py file/pathUsing the optimized version on example_score.txt prepared here will output the following result
Player 1, beats: 53, instruments: {'3', '13'}
intervals: [[0, 1, '13'], [2, 3, '13'], [4, 5, '13'], [6, 7, '13'], [8, 15, '13'], [16, 17, '13'], [19, 20, '13'], [21, 24, '13'], [65, 66, '13'], [74, 79, '13'], [84, 86, '13'], [91, 92, '13'], [94, 95, '13'], [101, 102, '13'], [103, 105, '13'], [106, 109, '13'], [34, 38, '3']]
Player 2, beats: 47, instruments: {'22', '12', '5'}
intervals: [[0, 15, '12'], [18, 19, '12'], [21, 22, '12'], [23, 24, '12'], [66, 71, '12'], [79, 80, '12'], [83, 84, '12'], [85, 86, '12'], [95, 96,
'12'], [98, 100, '12'], [104, 105, '12'], [16, 17, '22'], [47, 50, '5']]
...
Player 13, beats: 31, instruments: {'F#', 'C', 'C#'}
intervals: [[32, 36, 'C'], [46, 48, 'C'], [62, 65, 'C'], [100, 102, 'C'], [86, 90, 'C#'], [52, 54, 'F#'], [38, 42, 'F#'], [104, 106, 'F#']]
This shows that at minimum 13 players are needed to play this score. In this example, Player 1 plays the instruments numbered '3' and '13' in the intervals listed above.
The normal assignment will output the following result
Player 1, beats: 48, instruments: {'13'}
intervals: [[0, 1, '13'], [2, 3, '13'], [4, 5, '13'], [6, 7, '13'], [8, 15, '13'], [16, 17, '13'], [19, 20, '13'], [21, 24, '13'], [65, 66, '13'], [74, 79, '13'], [84, 86, '13'], [91, 92, '13'], [94, 95, '13'], [101, 102, '13'], [103, 105, '13'], [106, 109, '13']]
Player 2, beats: 41, instruments: {'12'}
intervals: [[0, 15, '12'], [18, 19, '12'], [21, 22, '12'], [23, 24, '12'], [66, 71, '12'], [79, 80, '12'], [83, 84, '12'], [85, 86, '12'], [95, 96,
'12'], [98, 100, '12'], [104, 105, '12']]
...
Player 16, beats: 13, instruments: {'F#'}
intervals: [[38, 42, 'F#'], [52, 54, 'F#'], [59, 60, 'F#'], [104, 106, 'F#']]
Numusic is designed as a language design project during my internship at Nau Data Lab.
