TL;DR: An evaluation of five Transformer models for chord-conditioned symbolic melody and bass generation in Classical style.

Abstract: We evaluate five Transformer-based strategies for chord-conditioned melody and bass generation using a set of music theory–motivated metrics capturing pitch content, pitch interval size, and chord tone usage. The evaluated models include (1) no chord conditioning, (2) independent line chord-conditioned generation, (3) bass-first chord-conditioned generation, (4) melody-first chord-conditioned generation, and (5) chord-conditioned co-generation. We show that chord-conditioning improves the replication of stylistic pitch content and chord tone usage characteristics, particularly for the bass-first model.
