Revolutionizing Melodic Harmonization with Curriculum Masking
This paper introduces the Full-to-Full (FF) training curriculum for single-encoder melodic harmonization, addressing the issue of weak melody-harmony attention in existing transformer models. By initially masking all harmony tokens and gradually unmasking them, FF forces models to leverage melodic cues more effectively, leading to robust and adaptable harmonic generation, especially in out-of-domain contexts like jazz standards.

Q1: FF Curriculum vs. Baselines
Q2: Quantization Effectiveness
Q3: Bar Info Encoding
Q4: Melody Representation
Q5: FF with Efficient Inference
The proposed FF training curriculum consistently outperforms existing MD and R10% approaches across nearly all metrics, particularly in out-of-domain settings. It demonstrates superior capacity to adapt harmonic choices to the underlying melody, leveraging melodic nuances more effectively than baselines which tend to rely on rigid harmonic patterns.
Quarter-note (q4) quantization consistently yields stronger results than sixteenth-note (q16) quantization for the best-performing FF-trained models. While some MD variants favored q16, q4 is the clear advantage for FF models, striking a better balance for harmonic detail.
Intertwining bar information directly into the tokenization generally improved performance for FF-trained models compared to using time signatures as external conditions. This advantage was more pronounced in out-of-domain datasets, suggesting a more integrated structural understanding.
Using only pitch classes (PC) for melody representation is not only sufficient but often advantageous for FF-trained models. While one metric marginally favored FRPC in in-domain, all best-performing FF variants relied solely on PC in out-of-domain, highlighting the importance of chroma information over full range for harmonic context.
The FF training curriculum maintains its effectiveness across all inference-time unmasking strategies (uMD, uR10%, and Seq). Notably, uMD and uR10% protocols, which require fewer model calls, perform among the top setups, demonstrating that FF can be paired with more efficient inference methods without significant loss.

Jazz Standard Harmonization Success
Description: Our FF curriculum was rigorously tested on a curated collection of jazz standards, a notoriously challenging domain for melodic harmonization. The results demonstrate unparalleled adaptability to complex melodic structures.
Problem: Traditional models struggled with the nuanced, improvisational nature of jazz melodies, leading to rigid and unadaptable harmonic choices and poor alignment with melodic intent.
Solution: The FF curriculum's explicit design for strong melody-harmony conditioning from early training enabled the model to develop a profound understanding of melodic cues, resulting in highly flexible and stylistically appropriate harmonizations.
Impact: This led to a significant increase in harmonic diversity and structure (CHE, CC) and vastly improved melody-harmony alignment (CTnCTR, PCS) in out-of-domain jazz contexts, setting a new benchmark for generative quality.
