How to keep melody and style, but change the lyrics

[duckfriend123]

I found this video on youtube wellerman remix.webm https://www.youtube.com/shorts/ubA5FwG8Ngs

where somebody took wellerman, but kept the melody somewhat in tact but changed the lyrics.

I'm wondering how you could do this here.

I'm pretty sure Suno was used, but it must be possible to do this with ace step too, right?

As it happens I did this with ACE. I'm using the turbo model. I uploaded the song with the original lyrics and then chose Remix and I did enter the new lyrics in the Lyric field. It generated the same song (same instruments and same voice) but with the new lyrics. I did only one batch and it was not perfect e.g. some lines of the new lyrics were missing, but maybe with finetuning you can get better results.

The most useful fix when lines disappear is usually to preserve the song structure as well as the words. In Cover/Remix, keep the same section order and similar line lengths, then make each replacement line close to the original syllable count. The ACE-Step tutorial recommends about 6-10 syllables per line and keeping corresponding lines within roughly 1-2 syllables. Keep the duration near the source; a higher Audio Cover Strength follows the source structure more closely, but it cannot guarantee every new word will be sung. If a line is skipped, shorten or rephrase that line and generate a few variants. Guide: https://github.com/ace-step/ACE-Step-1.5/blob/main/docs/en/Tutorial.md
