AI sheet music editor that shows its work

The assistant in ScoreStarling is called Starling. It works on the score in front of you: open a file, select the bars that need changing, and ask in words. It is the same assistant on its own page, where you can start from a recording, a video, a song link or a score file, and beside an open score in the workspace.

What goes in and what comes out

How it works

1. Choose a score or a recording above. The workspace opens with it; if you need to sign in first, it waits in this browser.
2. Create the score, or open the one you already have, then choose Starling beside it.
3. Select the bars you mean and ask for one change: a key, a hand, an instrument, a simpler passage.
4. Read the reply and check the marked notes, listen against the recording, undo the reply if it is wrong, then download.

What can you ask for?

• A new key: “move it up a whole step so I can sing it in A” moves the key signature, chords and every note together.
• An easier passage: a simpler left hand, fewer notes in a fast run, dynamics that fit an adult beginner.
• Another instrument: a part for flute, clarinet or cello, with the range and clef that instrument reads.
• Less: the melody only, or a version with the accompaniment thinned out.
• A different view: jianpu, or guitar TAB in the tuning you play in.
• An export: PDF, MusicXML, MIDI, an audio file or all parts at once.
• A recording written out first, when the score does not exist yet.

How do you know what it changed?

• The notes it touched are marked on the staff, so the edited passage is visible.
• Its reply lists what its tools wrote, in the score’s own terms: a clef from treble to bass in bar 4, a key from C major to F major.
• An edit that would leave the score as it was is refused with “Nothing changed”, not reported as done.
• Undo takes back everything one reply changed, and each change is a saved version.
• Play the result against the recording or the previous version before you print it.

The thinking behind those checks, including a failure of ours and the fix, is in Can an AI assistant edit sheet music for you?

Good to know

• Starling is an early beta. It can mishear a note in a recording it writes out, misread a crowded page, or stop partway through a long job; check the bars it touched.
• Replies cost about 1–5 credits, never more than 10. A transcription or a band it starts uses its own price, shown before it begins.
• Jianpu is a read-only view; edit in staff notation. Guitar TAB has no bends, slides, hammer-ons or chord diagrams, and keeps one tuning and capo per piece.
• A recording contributes its first six minutes, a PDF up to 12 pages, and notation playback runs to ten minutes.
• MusicXML, MIDI and Guitar Pro downloads come with Plus or a credit pack; PDF, MP3 and WAV with every account.
