Is there an AI plugin for MuseScore 4?
Yes. AiHud Notation Copilot is a plugin for MuseScore Studio 4 that opens a chat window next to your score. You type what you want ("write a walking bass in bars 1-16", "make the trumpet part easier") and it writes the notes straight into the open score as one undo step. It is free for 100 applied edits a month.
It is built for the jobs that take an hour of clicking: section voicing, string pads and brass hits, bass lines, simplified parts for students, doubling and transposing lines, writing melodies and exercises, slurs, articulations, dynamics and hairpins. It only changes the parts and bars you ask about.
How it works: install in 4 steps
- Get a free key on copilot.aihud.net and click “Download the plugin”. The zip has your key built in, so there is nothing to paste.
- Unzip it into your MuseScore plugins folder, so you end up with a
NotationCopilotfolder there:
Windows:Documents\MuseScore4\Plugins\
Mac:Documents/MuseScore4/Plugins/(in Finder: Go → Home → Documents)
Linux:~/Documents/MuseScore4/Plugins/ - Restart MuseScore 4, open Home → Plugins and click Notation Copilot → Enable.
- Open a score and choose Plugins → Composing/arranging tools → Notation Copilot. Type what you want in the chat.
Example requests and what you get
voice the alto 1 melody in bars 1-8 for the saxes
Result: Alto 2, both tenors and the bari get close-voiced harmony under the melody, built from the chord symbols, each part in its instrument's range.
add a walking bass line in the bass, bars 1-8
Result: Quarter-note walking line: roots on the chord changes, chromatic approach notes in between.
add accents to the flute in bars 5-8
Result: Accents on every note in those bars, nothing else touched.
Honest limits
- It edits the score you have open; it can't add new instruments or staves. Add the staff in MuseScore first (press I), then ask Copilot to write for it.
- Each request is one undo step: one Ctrl+Z (Cmd+Z on Mac) puts the score back exactly as it was.
- It works in MuseScore Studio 4.x (Windows, macOS, Linux) and needs an internet connection; your score is sent to AiHud only to make the edit and is not stored.
- Big jobs (more than about 128 part-bars at once) ask you to confirm first. Vague requests get a short question with one-click options instead of a guess.
- It writes from your chord symbols, or from the harmony it reads in the score when there are none. It is a fast first draft: check it by ear like you would a student's or a colleague's part.
Price
Free for 100 applied edits a month, no card needed (questions and “nothing to change” replies don’t count). After that, pay as you go with AiHud credits: A request typically uses 10 to 25 credits (1 credit = $0.001); a request that needs a clarifying question costs two rounds. $10 is roughly 400 to 1,000 requests. See pricing.
