"Make a good song" leaves almost every decision open. You will usually learn more from a prompt that names the story and a few musical choices.
Start with a song you can describe in ordinary words. You do not need to know the name of every instrument or production effect.
Give it a subject
Say what happens in the song. "A song about friendship" is broad. "Two friends miss the last train and walk home together" gives the lyrics somewhere to start.
If you already wrote the lyrics, keep them separate from the musical instructions. Label verses and choruses so the intended structure is clear.
Describe the sound
Name a genre or a combination that makes sense to you. Then add the main instruments, the pace and the feeling.
Try "slow acoustic pop, piano and soft drums, warm and a little homesick." Every part tells the generator something different. You do not need ten adjectives that all mean sad.
Describe the voice
A close, quiet vocal sounds different from a large group chorus. Say which one you want. You can also ask for an instrumental if a lead voice would get in the way.
Include the language for a song with lyrics. It is a separate decision from the language in which you write the prompt.
Give the arrangement a direction
Tell the song where to grow or pull back. For example, start with piano and a quiet verse, bring in drums at the chorus, then leave space before the final chorus.
You can request a length or describe a section change, but treat that as guidance. A generated recording may not follow an exact timestamp or duration.
Put it together
Here is an original example:
A slow acoustic pop song in English about two friends walking home after missing the last train. Warm piano, soft drums and close, quiet vocals. Start with a sparse verse, then open up into a chorus they could sing together.
Listen for the specific choices you asked for. If the voice is too forceful, change the vocal direction first. If the track is too busy, reduce the instruments. Changing one thing makes the next result easier to judge.
A revised prompt produces a new recording. It does not preserve a melody or edit a selected part of the previous track.
