A red bar has more beats than the time signature allows.
Post to the community gallery
Every post goes into a review queue and is checked by hand. Nothing is public until it's approved. We store the sheet, the display name you type (optional), your note and the time. No email, no account. Please only post your own melodies or public-domain tunes.

Getting started
Note values, at a glance
Sheet music tells you two things about every note: how high it is (where it sits on the five lines) and how long it lasts (its shape). These are the lengths the editor writes.
Half note
2 beats. Open head with a stem.
Quarter note
1 beat, the pulse you tap your foot to.
Eighth note
Half a beat. One flag on the stem.
Sixteenth note
A quarter of a beat. Two flags.
Dotted quarter
A dot adds half the value: 1½ beats.
Quarter rest
One beat of silence. Every note value has a matching rest.
Sharp, flat, natural
♯ raises a note a half step, ♭ lowers it, ♮ cancels both.
Faster entry

Guide
How to write sheet music, step by step
Choose a clef
The treble clef is for higher parts: voice, flute, violin, guitar and the right hand on piano. The bass clef is for lower parts like cello, bass and the left hand. Pick the one where your melody needs the fewest extra ledger lines.
Set the time signature
The top number is beats per bar and the bottom number is which note gets the beat. 4/4 fits most pop, rock and lofi. 6/8 and 12/8 give a rolling, swaying feel. 2/4 suits marches. The editor draws bar lines for you as each bar fills up.
Pick a key signature
Sharps or flats placed after the clef apply to every matching note, so you don't have to write them each time. In this editor, new notes follow the key automatically. If you change the key later, notes that followed the old key move to the new one.
Write the rhythm and pitches
Choose a note length, then click where the note sits on the staff. Lines and spaces from the bottom of the treble staff read E G B D F (lines) and F A C E (spaces). Add sharps, flats or naturals to single notes as you need them. They last until the end of the bar, just like on paper.
Listen back and fix
Play from the start, or select a note to play from there. Turn on the click to check your rhythm against a steady beat. A bar drawn in red has more beats than the time signature allows.
Title it, then share or print
Add a title and composer, then copy a share link, download SVG or MIDI, or print to PDF. To keep a backup, download a file or save the link somewhere safe, since browser storage can be cleared.

FAQ
Questions about the sheet music app
Is this sheet music app free?
Yes. Sheet Music App is free to use in any modern browser on a phone, tablet or computer. There is no account, no download and no paid tier.
Where are my scores saved?
In your browser's local storage on this device. Every change saves automatically and your sheets appear under My sheets. Clearing your browser's site data deletes them, so copy a share link or download the SVG or MIDI file to keep a backup.
How does sharing a score work?
The whole score is packed into the link itself, after the # sign. Anyone who opens the link sees the same notes, title and tempo and gets their own editable copy. The link is not uploaded anywhere, so it keeps working as long as you keep it.
Can I post my sheet music publicly?
Yes, from the Post to gallery tab. Posts go into a review queue first and nothing appears in the gallery until it has been approved by hand. We store the sheet, the display name you type (optional), your short note and the time. We never ask for an email address or an account.
Can I print sheet music or save it as a PDF?
Yes. Use Print / PDF in the Share & export tab and choose Save as PDF in your browser's print dialog. You can also download the score as an SVG image, a MIDI file, or copy it as ABC notation.
Does it work on a phone?
Yes. Tap the staff to place a note, drag a selected note up or down to change its pitch, or use the on-screen piano under the staff. The toolbar wraps to fit small screens.
What can't it do yet?
It writes one melody on one staff. Ties, triplets, beams, chord symbols, lyrics and a second staff for piano are not built yet and are marked coming soon. For full scores, MuseScore Studio is a good free option.
Can I use the Purrple Cat songs on this page in my videos or my own music?
Yes. You can use Purrple Cat songs in your videos and streams, and in new songs, including on YouTube and Spotify, as long as you include the credit line: Music by Purrple Cat (purrplecat.com), licensed under CC BY 4.0: creativecommons.org/licenses/by/4.0/ What's not allowed: re-uploading the original beats as they are, or releasing remixes, covers or raps over the beats on streaming platforms.
