ACE MusicA Whole Song from the Melody in Your Head
Turn a hummed melody into a complete song with ACE Music. Prepare a clear recording, develop the lyrics and melody, and compare generated versions.
You can hum the tune. You might even know how the chorus should feel. But choosing chords, adding drums, and finding the right words can leave you stuck.
ACE Music’s Audio to Song gives that idea a practical starting point: record or upload your humming, describe the music you want, and generate a complete song. You can also develop the melody and draft lyrics before generating. The first result gives you something to listen to, compare with your original idea, and improve.
Prepare a clear melody and a little direction
Start with one phrase you can repeat. Record somewhere quiet, with your voice clearly audible and no competing music. You don’t need a polished performance, but the beginning, rhythm, and ending should be easy to hear.
Listen back and identify the part that matters most. Is it the repeated rhythm? The jump to a higher note? Keep the original recording so you can return to that detail later.
Prepare a short description of the song, too. For example:
A warm acoustic-pop song about leaving home, with guitar, light drums, and a hopeful chorus.
If you already have lyrics, keep them nearby. If you only have a subject or a single line, that’s a useful starting point.
Choose your generation path
Hear a musical direction first
If you mainly want to discover how your humming could sound with accompaniment, start in Idea.
In ACE Music, open Create → Idea and select the microphone control. Allow microphone access, record your phrase, stop, and listen. Choose Start over for another take or Done to use it.
For an existing phone recording, use the + menu and Audio file. Supported formats include MP3, WAV, M4A, FLAC, OGG, and AAC. Wait for both uploading and musical recognition to finish, then add your description.
Check the model and generation controls currently shown in your workspace. This walkthrough used ACE Music v1.1 Preview with an uploaded reference edited in the Songwriting Assistant. Model names and reference options can change; use the controls available for the selected model and check the displayed cost before generating.
Shape the melody and lyrics before generating
Choose Custom when you want to make more decisions about the tune and words first. Add your recording as a reference, or record directly through Audio → Record.
Once the recording has been read into a melody reference, open Edit melody. Compose with AI can develop an opening or revise existing notes. Describe what you want to change and what should stay.
Listen to the updated melody. In the main workspace, changes apply directly and can be undone. Choose Done to return the edited reference to Custom; a separate editor may instead use Apply.
For the words, open Lyrics and paste your draft or use Write lyrics with AI. Describe the subject, narrator, and emotional tone. Review the returned text and edit it yourself where needed.
Keep lyrics in Lyrics and musical instructions in Style. Labels such as [Verse] and [Chorus] help organize the words. Before generating, check that the attached melody, lyrics, and style all describe the same song.
A real walkthrough: develop an original melody into a vocal demo
For this walkthrough, we uploaded an original 10.6-second synthetic keyboard melody as a WAV file. It is an instrumental input, not a person humming into the microphone. After recognition, we opened Edit and used the Songwriting Assistant to develop the idea into verse and chorus sections. Keep your source file so you can compare the generated interpretation with your own phrase.
The uploaded reference is attached in Custom. Open Edit to work with its recognized melody.
Use the existing melody as a chorus motif. Build an eight-bar vocal verse followed by an eight-bar vocal chorus in C major at 100 BPM. Keep the rising idea recognizable in the chorus. Make the verse gentle and the chorus hopeful, in a comfortable singing range.
Describe the verse and chorus you want in Compose with AI, while keeping the original motif as a reference.
The developed score now has Verse and Chorus sections. Review the notes and chords before choosing Done.
The lyrics writer returned the following short English draft for the developed melody. We used these words in the generated examples. Review how each line fits the phrase and shorten any words that feel rushed.
[verse]
Cardboard boxes
Stack the hallway
I just called my mom to say I'm doing fine
[chorus]
Strange new window looks out on the street below
Tomorrow morning is where my new life starts
Warm acoustic pop about leaving home for a new city. Intimate expressive lead vocal, gentle piano, acoustic guitar, warm bass and light drums. Keep the verse conversational and let the chorus lift with hope. Use the edited melody reference as the starting point.
Put the musical direction in Style, check the reference and lyrics, then select Generate.
Two versions of First Night Unpacked have finished in Library, at approximately 41 and 39 seconds.
These are the two MP3 files downloaded from this run, approximately 41 and 39 seconds long. Listen for the phrase, lyric pacing and ending, then use this short demo to decide how to extend the song further.
Select MP3 in the actual result’s Download panel to save a listening copy.
Listen for the idea inside the result
Generation requests two versions, with progress and completed audio appearing in Library. Listen to both before choosing a direction.
First, compare each version with your original humming. Can you recognize the phrase you wanted to keep? Pay attention to its rhythm, highest note, and ending. The generated song may interpret these differently.
Next, listen to the lyrics without reading them. Are the important words understandable? Does a meaningful word land naturally, or does the singer rush through it?
Finally, listen to the accompaniment. Does it leave room for the melody? Does the chorus feel like a clear arrival after the verse?
Use those observations to choose your next adjustment. A wrong reference note calls for a melody edit. Overpowering instruments call for a clearer Style description. A crowded lyric line may need fewer words.
Put it into practice: develop a chorus about leaving home
Suppose your recording contains a short, rising phrase that feels like a chorus. You want to build a song around the mix of excitement and homesickness that comes with moving away.
Open the melody reference and ask Compose with AI:
Keep the opening phrase as the chorus idea. Add a gentler verse melody that leads into it.
Listen for a verse that gives the chorus somewhere to go. If one note feels wrong, the piano roll lets you move it to change its pitch or timing, adjust its length, or delete it. Use playback to check the change.
For lyrics, give the writer a concrete scene:
Write about the first evening in an unfamiliar apartment. Include unpacked boxes and a call home. Make the chorus hopeful, with short, conversational lines.
Try singing the draft over your phrase. If you have to squeeze in the final words, shorten the line or request a revision. Read the whole revision afterward, including lines you asked to preserve.
Make the next version with a clear purpose
Choose one main improvement for the next generation. You might keep the melody and words while asking for lighter percussion, or keep the musical direction while simplifying the chorus lyric.
Keep copies of the wording and recordings you like. Comparing versions is easier when you know what changed.
Before treating a result as finished, listen from beginning to end. Check pronunciation, repeated lines, transitions, and the ending. If you need an audio file for a demo, check the available downloads: access depends on your model, plan, and the files produced for that result. Download and plan details.
Q&A
Do I need to read music or know which chords to use?
No. You can begin with an audible hummed phrase and describe the sound in everyday language. Melody editing is available when you want more control, but you can first explore an arrangement through the recording-and-description route.
Can I change the lyrics after generating a song?
Yes, you can revise the text for another generation. In ACE Music, the lyrics writer changes the Lyrics field; it does not replace vocals inside an existing audio result. Generating again lets you hear the revised words, though other musical details may also change.
Can I repair just one part of my humming recording?
The quick recording panel supports replacing the whole take, but it does not trim audio or re-record individual sections. For those changes, edit the file in audio software before uploading it. If the melody has been recognized, you can separately correct its notes in the melody editor. Recording editing limits.
