If you mostly write lead sheets and you were using Finale, you are probably looking for the right tool to switch to, since it stopped being developed in August 2024.
Lead sheet work leans on a short list of things: chord symbols that sit cleanly over the melody, navigation markers a player can follow at tempo, slashes for the comping bars, playback with a swing feel, and a way to give a horn player the chart in their key. Your existing charts also have to come across, and that depends on what your old files will export rather than on which editor you prefer.
Here is what to check, and how Flat handles each of them.

Where your charts stand now that Finale is unsupported
Finale still opens on any machine where it is already authorized, and MakeMusic has said that downloading and authorizing registered products stays available for the foreseeable future. So there is no cliff edge. What there is instead is a slow narrowing: development ended, technical support has closed, and every operating system release from here is one the application was never tested against. Plenty of people will get another few years out of it.
For a gigging player this lands differently than it does for a composer. A book of charts is not an archive. It is what you reach for on a Friday when someone calls a tune in a key you did not write it in. Heads, intros, tags, the transposed version you made for one particular horn player: most of it exists in one copy only. So it is worth choosing deliberately rather than taking the first recommendation from a forum. If you want the wider field first, we looked at the main Finale alternatives separately.
What to look for in a Finale alternative for lead sheets
Lead sheets have a short list of requirements that are easy to miss when you are reading feature grids. These are the ones worth testing against your own book.
- Chord symbols over the staff. The chords are the chart, so test this first. Check that symbols sit cleanly above the melody and that extensions and alterations are easy to reach. Flat supports a long list of chord qualities, and can show guitar chord grids under the symbols when a fretted player needs them.
💡 Add a chord notation. - Navigation markers and repeats. Charts run on segno, coda, D.S., D.C., To Coda and Fine, plus first and second time endings. The player has to follow the route at tempo, so these need to be quick to place and clear to read. Flat has all of them in the measure menu, with repeat endings as their own tool.
💡 Measure tools. - Slash and rhythmic notation. Comping bars need slashes, and sometimes slashes with a written rhythm rather than four to the bar. Flat does both.
💡 Slash and rhythmic notation. - A swing setting for playback. Playback that reads eighths straight is not much help when you are checking a tune you just wrote. Flat applies swing from the measure menu, including swing eighths for the standard jazz feel.
💡 Swing eighths and sixteenths. - Transposed parts from the same chart. Somebody always needs it in their key. Flat can show a score in concert pitch or in each instrument's written pitch, so one chart covers the B flat and E flat players without a second file.
💡 Display the score in concert pitch. - Getting the chart onto the stand. Every score in Flat sits behind a link, and its privacy setting decides what people can do with it. The link opens in a phone or tablet browser, so the band reads the chart itself instead of a photo of a page.
💡 Share and collaborate. - A clean PDF when you want paper. Plenty of rooms are wrong for a screen. Flat exports the full score, one part or a set of parts, as PDF, MIDI or MusicXML, plus an MP3 or WAV of the playback.
💡 Print and export your scores. - Somewhere to keep a lot of tunes. A book grows quickly, and one long list stops helping somewhere around the fiftieth chart. Flat uses collections, so you can group by band, by set or by session.
💡 My Library: collections.
How easily your existing charts transfer
Moving a book is quicker than most people expect. Export from Finale while you still have a working installation, since its own files open only in Finale and MusicXML is the way out. You do not have to go one at a time either: Finale batch exports to MusicXML, so several hundred charts can leave in a single pass. There is a step-by-step guide for the Finale end of this, and Flat reads the resulting files directly. Melody, chord symbols and most markings arrive intact, though it is worth checking that codas and repeats landed where you meant them.
Anything that will not export, or only ever existed on paper, comes in another way. Flat imports PDFs and turns them into editable scores, so a chart someone handed you years ago needs no retyping. If you are starting a new chart instead, we have a walkthrough on building a lead sheet in Flat.
Why Flat works for lead sheets
The chart goes where you go. Flat runs in a browser and as apps on iOS and Android, so the tune you wrote at the kitchen table is the tune you pull up on your phone at the gig. Nothing to export, no file to email yourself. If you have ever turned up to a session and found the current version of a chart sitting on a laptop at home, that is the argument in one line.
Writing with other people is easier too. Two players can be in the same chart at once, so a bandleader and a horn player can settle a voicing without trading attachments and guessing which file is current. And when you want to see how someone else laid a tune out, the public scores in Flat's community can be copied into your own library and taken apart.

FAQ
What should I look for in a Finale alternative for lead sheets?
Chord symbols, navigation markers such as segno, coda, D.S. and D.C., repeat endings, slashes for the comping bars, a swing playback setting, and one-step transposition so you can give a horn player the chart in their key.
Can Flat open Finale .mus or .musx files directly?
No. Finale's native .musx and .mus files can only be opened in Finale itself, so you export them as MusicXML from a working Finale installation and import that into Flat. Charts you can no longer open in Finale can be brought in as PDFs.
Can I export all my Finale files to MusicXML at once?
Yes. Finale can batch export to MusicXML, so a book of hundreds of charts can be converted in one pass rather than opened and saved one at a time.
Does Flat play back a chart with a swing feel?
Yes. Flat has a swing setting applied from the measure menu, including swing eighths for the standard jazz feel, so playback matches how the chart is meant to be read.
Can I get a transposed part for a horn player from the same chart?
Yes. Flat can show a score in concert pitch or in the written pitch of each transposing instrument, so one chart covers a B flat or E flat player without a second file.
Does everyone in the band need an account to read a chart?
No. A private sharing link lets anyone in the band open and read a chart without creating an account, and it works in a phone or tablet browser on the stand. You can also export a PDF to print.
