Model Overview This multi-model music generator combines several AI-powered music models to create unique compositions across different genres and styles. By integrating models like MelodyRNN, MuseNet, MusicVAE, and Dance Diffusion, this system generates complex, layered music that includes melody, harmony, rhythm, and even synthesized vocals.

Users can control aspects like genre, tempo, and instrumentation to customize the output to their preferences, making this generator a versatile tool for producing music in styles ranging from classical to electronic and jazz.

Intended Uses & Limitations Intended Uses Music Creation: Generate music compositions for inspiration or background tracks. Genre Experimentation: Users can select different genres and experiment with AI-generated music in various styles. Educational Use: For those learning about AI in music, this model demonstrates how different generative models can combine to produce rich audio outputs. Limitations Quality Consistency: While this model creates cohesive compositions, generated music may vary in quality based on genre and user settings. Computationally Intensive: Combining multiple models can require significant computing power, especially for longer compositions. Experimental: AI-generated music may not match the nuances of professionally composed music. How It Works This music generator is built on a pipeline that combines multiple specialized models:

Melody Generation: Starts with MelodyRNN to create a primary melody. Harmonic Support: Adds harmonic layers using MuseNet for chords and structure. Rhythmic Layer: Uses Dance Diffusion to add rhythm, optimized for genres like electronic and pop. Additional Effects: Optional effects and synthesized vocals are added with Jukebox for fuller compositions. Each model’s output is synchronized to maintain consistency in tempo, key, and style, resulting in a unified music track.

Model Details Input Format Text Prompts: Users provide prompts (e.g., “A jazz melody in C major”) to guide music style. Sliders: Control parameters for tempo, genre, and melody complexity. Output Format MIDI Files: Generated music is initially created as MIDI files, which can be converted to audio formats. WAV/MP3 Files: Final output is rendered in audio formats for easy playback. How to Use Code Example You can use this model directly on Hugging Face Spaces with the Gradio interface or integrate it into your own Python code:

python Copy code from transformers import AutoModelForCausalLM, AutoTokenizer import torch

melody_model = AutoModelForCausalLM.from_pretrained("your_model_repo/multi-model-music-generator") tokenizer = AutoTokenizer.from_pretrained("gpt2")

prompt = "A smooth jazz melody with a lively rhythm"

inputs = tokenizer(prompt, return_tensors="pt") outputs = melody_model.generate(inputs['input_ids'], max_length=200)

generated_music = tokenizer.decode(outputs[0], skip_special_tokens=True) print(generated_music) Training Details This model leverages pre-trained components for each role in the music generation pipeline:

MelodyRNN for melody generation MuseNet for harmony and chord progressions Dance Diffusion for rhythm layers Jukebox (optional) for vocals and ambient effects Each component was fine-tuned on specific datasets like the Maestro dataset for classical music or the Lakh MIDI dataset for pop and jazz to optimize results across genres.

Evaluation Generated compositions were evaluated based on:

Coherence: How well the melody, harmony, and rhythm layers fit together. Genre Fidelity: Whether the output aligns with the genre specified in the prompt. User Preferences: User-adjustable parameters allow for varied outputs. Ethical Considerations Copyright: Be cautious when using AI-generated music commercially. Some datasets may contain music with copyright restrictions. Biases: AI music generation may reflect biases present in training datasets, such as a preference for Western music structures. Originality: This model produces unique compositions, but AI-generated music may lack the depth of human-composed music. Acknowledgments This project combines models by various research groups:
