Generalized Mathematical Music Neural Network Architecture Specification
Neural Architecture Instructions for Generating the Musical Artwork
[^1]
Let me break down each section and explain how they work together:
Input Processing:
Tokenizer --> |Embeddings| Transformer[Math Understanding Transformer]
Mathinput[Mathematical Formula/Concept] --> Tokenizer[Custom Math Tokenizer]
GenreInput[Genre Specification] --> StyleEncoder[Style Embedding Layer]
This section handles two parallel inputs:
- Mathematical Input: Say we input "T(H) function composition". The Custom Math Tokenizer would break this into meaningful tokens like ["T(", "H", ")", "function", "composition"], similar to how GPT tokenizes text, but specialized for mathematical notation.
- Genre Input: When we specify "Mathematical Hip-Hop", the Style Embedding Layer converts this into a vector representation that captures musical characteristics of hip-hop.
Core Architecture:
StyleEncoder --> |Style Vectors| StyleMixer[Style Conditioning Layer]
Transformer --> |Encoded Patterns| LSTM1[LSTM Pattern Generator]
This is where the magic happens:
- The Transformer (similar to GPT architecture) takes those math tokens and generates a deep understanding of the mathematical patterns
- The LSTM Pattern Generator takes these patterns and starts generating basic musical structures
- The StyleMixer combines these with the genre characteristics
Musical Elements Generator:
LSTM1 --> |Contours| RNN3[Melody RNN]
LSTM1 --> |Base Patterns| RNN1[Rhythm RNN]
LSTM1 --> |Progressions| RNN2[Harmony RNN]
This splits the musical generation into three parallel streams:
- Rhythm RNN: Generates rhythmic patterns that reflect the mathematical transformations
- Harmony RNN: Creates chord progressions that represent state spaces
- Melody RNN: Develops melodic lines that embody the mathematical processes
Generation Pipeline:
Quantizer --> MidiGen[MIDI Generator]
EventSeq --> |MIDI Events| Quantizer[Musical Quantizer]
StyleMixer --> |Styled Patterns| EventSeq[Musical Event Sequence]
This converts the abstract musical patterns into actual music:
- Musical Event Sequence: Combines rhythm, harmony, and melody into a single timeline
- Quantizer: Ensures everything aligns to musical time (like snapping to a grid)
- MIDI Generator: Produces playable MIDI files
Validation:
Backprop --> |Adjustments| LSTM1
MidiGen --> |Generated MIDI| RuleCheck[Rule-Based Validator]
RuleCheck --> |Validation Score| Backprop[Backpropagation Loop]
This ensures quality and accuracy:
- Rule-Based Validator: Checks both musical rules (like proper harmony) and mathematical validity
- Backpropagation Loop: Feeds errors back to improve generation
Training Data:
Rules[(Validation Rules DB)] --> RuleCheck
MathCorpus[(Mathematical Corpus)] --> Transformer
MusicDataset[(Genre-Labeled MIDI)] --> StyleEncoder
The knowledge bases:
- Mathematical Corpus: Repository of mathematical concepts and their relationships
- Genre-Labeled MIDI: Database of music in different styles
- Validation Rules: Both musical theory rules and mathematical validity checks
