MusicLang Chord Predictor model

MusicLang Chord Predictor is a model for creating original chord scale progressions in the musiclang format with generative AI model.

It can be used for different use cases :

• Predict a chord progression from scratch (a fixed number of chords)
• Continue a chord progression (using a MusicLang prompt)

If you are only looking to generate chord progressions in an easily readable format, consider using our text chord predictor

To make the prediction we have an inference package available here : MusicLang Predict which is based on the musiclang language : MusicLang.

Installation

Install the musiclang-predict package with pip :

pip install musiclang-predict

How to use ?

1. Generate a 4 chords progression in few lines :

from musiclang_predict import predict_chords, MusicLangTokenizer
from transformers import AutoModelForCausalLM, AutoTokenizer
from musiclang.library import *

# Load model and tokenizer
model = AutoModelForCausalLM.from_pretrained('musiclang/musiclang-chord-v2-4k')
tokenizer = AutoTokenizer.from_pretrained('musiclang/musiclang-chord-v2-4k')
soundtrack = predict_chords(model, tokenizer, nb_chords=4, temperature=1.0)

# Give the chord a simple voicing (closed position chord)
soundtrack = soundtrack(b0, b1, b2, b3)

# Save it to midi
soundtrack.to_midi('song.mid', tempo=120, time_signature=(4, 4))

2. Use a prompt

from musiclang_predict import predict_chords, MusicLangTokenizer
from transformers import AutoModelForCausalLM, AutoTokenizer
from musiclang.library import *

prompt = (I % I.M) + (V % I.M)['6'].o(-1)

# Load model and tokenizer
model = GPT2LMHeadModel.from_pretrained('musiclang/musiclang-chord-v2-4k')
tokenizer = AutoTokenizer.from_pretrained('musiclang/musiclang-chord-v2-4k')
soundtrack = predict_chords(model, tokenizer, nb_chords=4, prompt=prompt)

# Give the chord a simple voicing (closed position chord)
soundtrack = soundtrack(b0, b1, b2, b3)

# Save it to midi
soundtrack.to_midi('song.mid', tempo=120, time_signature=(4, 4))
