[teleMelody] How to modify the tonality in the inference code?

[elricwan]

Hi there, Thank you first for providing the great checkpoints so that I can play with some examples. During the experiments, I notice that I could modify the chord file to control the chord progression. From the paper, I also notice that the tonality could be controlled, but I did not find a place to modify this value. so how could we control the tonality during inference?

Thank you.

Hi @elricwan . You can modify the mode variable ( MAJ or MIN ) in the code to control the tonality during inference.

Hi @jzq2000 ,Thank you for the explanation! By the way, there are many more tonality exists like C, D, E, F, G, etc. Is there a specific reason that teleMelody trained on the C major and A minor tonality?

Thank you.

@elricwan Yes. It is a common trick since transposition (other majors to C major / other minors to A minor) is trivial and rule-based. Thus, we need to consider one specific major and one specific minor, and normalize other tonalities to these two.
