Use the AI piano music generator to turn a text prompt into a piano instrumental. Free to start, no credit card, with a piano you can play online.
AI piano music is a piano-led instrumental composed by an AI model from a short text prompt. The AI piano music generator turns a plain-language idea into a piano-led instrumental, free to start, with included credits and no credit card required. You can make your first piece in just a few clicks over at the AI piano music generator.
How to make piano music with AI
Describe the piano piece you want
Type a prompt describing the piece you have in mind. The text box holds up to 2000 characters, so there is room to be specific. The details that steer the result most are mood, tempo in BPM, and key. A prompt like "A calm cinematic piano piece in A minor, 76 BPM, gentle left-hand arpeggios" gives the model clear direction.
Not sure where to start? Click Try an idea to fill the box with an example prompt you can tweak. The on-screen piano keyboard sits right below the prompt, so you can try out ideas before you commit.
Pick a model and create
Choose a model from the picker. CYM-Prelude is free, costs 4 credits, and composes up to 30 seconds, which is ideal for a quick sketch. CYM-Nocturne is available on the Starter plan and above, costs 15 credits, and composes up to 3 minutes for a longer piece.
Once you have picked a model, click the create button. It shows the cost up front, for example "Create Piano · 4 credits".
Play, download, and play along
When the model finishes, your piece streams in the built-in site player. Like the result? Download it as an MP3 audio file to keep.
You do not have to wait around while it works. Play the on-screen keyboard with your mouse, a touchscreen, or your computer keyboard keys while the next idea composes in the background.
For a more controlled result, name the mood, tempo (BPM), and key right in your prompt. A good habit: sketch cheaply with CYM-Prelude first, then switch to CYM-Nocturne for the longer version.
Piano prompt ideas to try
Not sure what to type? The clearer your prompt, the closer the result. Try one of these and adjust the mood, tempo, or key to taste:
- Lo-fi piano beat for studying, soft and warm
- Cinematic piano theme in D minor, slow and building
- Romantic solo piano ballad, gentle and expressive
- Upbeat ragtime piano, lively and bouncy
- Ambient piano for sleep, sparse and calm
- Reflective jazz piano, late-night and mellow
Name the mood, add a tempo in BPM, and pick a key when you want more say over the arrangement.
Two models in the AI piano music generator
The AI piano music generator gives you two models, so you can match the model to the job.
CYM-Prelude
Free tier. 4 credits per generation. Composes up to 30 seconds. Best for sketching an idea or testing a prompt.
CYM-Nocturne
Starter plan and above. 15 credits per generation. Composes up to 3 minutes. Best for a longer, more developed piece.
Use CYM-Prelude when you are exploring and want quick, low-cost passes. Switch to CYM-Nocturne when you have landed on a direction and want a longer piece. Both models compose a piano-led arrangement. The keys lead, and the model may add subtle texture underneath to support them.
If you want sharper prompts, the Styles and genres guide covers how to describe mood and feel. New to the platform? Start with Getting started.
