Behind the scenes with MuseScore 4's design and engraving improvements


Today’s release of MuseScore 4 is a major update and quite possibly the most significant one in the open-source application’s history since the release of MuseScore 1.0 in 2011. It includes major improvements to the user interface, layout, engraving, and playback features.

MuseScore 4 is delivered via a hub which installs both the MuseScore scoring application and the orchestral plug-in Muse Sounds. The MuseScore application can be downloaded separately, as well.

Not coincidentally, this is also the first major version of of MuseScore to be released under the product leadership of Martin Keary, Muse Group’s vice president of software (Tantacrul). Coming nearly two years after the last MuseScore update (3.6) and nearly four years after the release of MuseScore 3, Martin told Scoring Notes today that, “I’ve worked on a lot of complex creation software and this is the largest release I’ve ever put out,” including the launch of Paint 3D and a variety of PS3 games.

Muse Hub

One of the first changes to MuseScore that users might encounter is a new way to install the application to begin with. Muse Hub is a small utility application, which — as its name implies — brings together many of Muse Group’s software products in one place.

Muse Hub

From the menu bar (macOS) or System Tray (Windows), you can install MuseScore 4, as well as other applications like Audacity, and even content for these audio applications, like audio loops, effects, and virtual instruments (more on those later).

Muse Hub may seem extraneous at first, especially if you only use MuseScore, but I suspect that as the content libraries grow and the Muse Group family of applications matures, it will be a utility that offers quite a bit of, well, utility. You don’t need to keep Muse Hub running in the background to use MuseScore, and it is possible to download and use MuseScore separately without installing the Hub at all, if you don’t want to use Muse Sounds (more on those sounds later).

User interface overhaul

The next update users will encounter is the completely rebuilt MuseScore user interface. Things are mostly laid out in the same ways as they have been in MuseScore 3.6, but with an updated, flat style. The team has rebuilt it using more modern technology, which allows for much greater flexibility and customization.

I’m quite fond of the new theme options, which allow you to work in dark or light mode, and select an accent color. But the real fun (and utility) comes from the customizable tool layouts.

The main note input toolbar across the top of the MuseScore window is probably the thing users interact with the most when working with MuseScore, especially new users who are still learning keyboard shortcuts. Not only is this deeply customizable in MuseScore 4, it’s easy and obvious how that works.

Click the gear to bring up a long list of everything that can appear in this bar, and hide, show, or reorder to suit your needs. For example, I don’t remember the last time I entered a 64th note, so I can just hide that until I need it. Also notably, some of the default tools here have changed, including the addition of common articulations, which had previously been hidden away in the Articulations palette. (That’s one fewer excuse my composition students will have for leaving them out!)

Easily customize the main toolbar to your needs. Reorder, hide, and show any of these tools with a click.

Panels in MuseScore 4 can be moved around much more freely as well, including the handy ability to stack them on top of one another, and quickly switch by clicking tabs across the top. This is a really nice way to get quick access to some less frequently used panels without having to keep them on the screen all the time or return to the View menu.

Speaking of panels, I want to call out the two most notable updates among them. First is the Properties panel, which replaces the old Inspector panel. It has most the same functionality, but has been completely reorganized and redesigned. Now when you change a notehead, you do so from a graphical list, rather than a dropdown of inscrutable names like “With X”. In MuseScore 3.6 the Inspector felt a bit like editing a spreadsheet. In MuseScore 4, it feels like working with music.

The Mixer panel has probably received the most attention of all. It now looks much more like the kind of mixer you might see in a digital audio workstation (DAW), which is to say it looks more like a hardware mixer. It also docks nicely to the bottom of the window, much as in other music and audio applications. The Mixer panel now also includes a track for the metronome, as well as a visual volume meter for each track, something that the MuseScore 3.6 mixer lacked.

I’ve described just a fraction of the updates that have come to MuseScore’s user interface. Some are more superficial like the welcome new note entry icon, while others are much deeper and function-altering — be sure to explore the revised New Score dialog(!). As a whole they really make MuseScore look like a modern application for the first time.

Engraving improvements

As lovely as the new user interface in MuseScore is, I would argue that it is far less consequential than the updates that have been made to the functionality of the application, starting with engraving.

MuseScore 3.6 already took major strides with the implementation of a new SMuFL-compliant music font called Leland, which was a dramatic improvement over the previous default, Emmentaler. While the font was an easy target when identifying the limitations of work produced in MuseScore, it was — if anything — of less concern than issues of collisions and spacing.

It’s worth getting into why this is a big deal coming from MuseScore 3.6. For me, horizontal (rhythmic) spacing has long been the most glaring weakness of MuseScore’s engraving features. Depending on the content, MuseScore would space some measures too tightly and others too loosely. In any place where there were different rhythms happening at the same time, it nearly always created inconsistent, hard-to-read notation.

Unlike collisions, which are usually obvious errors, it can be hard for new users to identify bad spacing, to say nothing of knowing how to correct it. For MuseScore’s user base, which is includes many who are new to music notation and engraving, this presents a particularly acute issue. That’s why I think it is so important to see the improvements in MuseScore 4.

Here is a very simple example of a passage that MuseScore 4 handles much more gracefully than earlier versions.

Image showing spacing issues in MuseScore
Rhythmic spacing is an area of major improvement in MuseScore 4.

Most obviously, notice that MuseScore has given the whole notes a lot more space, and even the eighth notes have slightly more space. The whole notes are less cramped and read more like the long sustains that they are. There is also extra space for the eighth notes, which is more subtle and allows room for small adjustments to distribute them optically evenly. Notice that 3.6 appears to give a lot more extra space to the flat sign and a little bit less space to the ledger line, which makes the D look much longer than the C before it. MuseScore 4 makes this rhythm appear as consistent and steady as it sounds.

Another spacing issue in MuseScore 3.6 that is corrected in 4.0 occurs when different parts play conflicting rhythms. This is particularly apparent when tuplets are added, as in this example.

MuseScore spacing problems for cross-rhythms
MuseScore 4 also addresses many of the issues in spacing for cross-rhythms like this.

Notice that previous versions of MuseScore gave rather sporadic spacing to the consistent tuplet rhythm to make it align to the simpler 3/4 rhythm in the upper voices. In MuseScore 4, this is corrected and both rhythms are now spaced proportionally.

The other major update to MuseScore’s engraving ability comes in the form of collision detection, especially for slurs and ties.

Comparison of MuseScore's handling of slurs and ties
Slurs and ties have gotten much smarter in MuseScore 4 as well.

Not only does the rhythm spacing make this first slur very difficult to read, the second slur cuts through the natural sign. The ties in the chord at the end cut awkwardly through the space of the dots. MuseScore 4 brings a much more sophisticated system for identifying and automatically correcting these kinds of errors.

You can read in great detail about all of the engraving improvements in MuseScore 4 on the MuseScore site.

All-new playback system

I’ve already mentioned the Mixer’s new look, and it’s not just prettier. It’s also more functional.

In addition to the new volume meters, you’ll also find new playback sound options. MuseScore 4 is now capable of working directly with VST3 instruments, so you can work with your favorite sounds from Kontakt, Spitfire, EastWest, etc.

Select any VST instrument right in the MuseScore 4 mixer.

VST3 support also extends to effects plugins. There is a new FX insert on each channel in the mixer. Just like a DAW, you can add any chain of effects to an individual instrument channel or the master channel. I do wish it was possible to reorder the effects chain after I’ve started, and I have experienced a lot of speaker pops and artifacts when adding and removing effects, which I expect to be ironed out soon.

You can also add any VST effects in MuseScore’s mixer, either to individual instruments or to the master track.

The playback system is completely rebuilt from the ground up to support modern audio tools and workflows. One notable addition is the support for the playback of accelerando and ritardando lines, a “hallelujah” moment, according to Martin.

In addition to this new audio engine, Muse Group has also produced a new set of virtual instruments to go with it.

Muse Sounds

For all the improvements to interface and engraving, and as welcome as all those changes are, it’s really Muse Sounds that steals the show here.

In May of last year, Muse Group acquired StaffPad, an application perhaps best known for two things: handwriting input and excellent audio. Leveraging the expertise of StaffPad’s development team, MuseScore has developed and built its own system for playing back real recorded samples in a similar way.

These brand new instrument samples, recorded by StaffPad founder David William Hearn, are downloadable for free within Muse Hub and usable immediately from within MuseScore 4 without any configuration. You can download individual instrument families as needed from the following:

  • Muse Brass
  • Muse Choir
  • Muse Harp
  • Muse Keys
  • Muse Percussion
  • Muse Strings
  • Muse Woodwinds

Even if you — like me — decide to download the whole collection, it comes in at 14.4 GB, which is svelte for such an impressive sound library. The way these are named, as well as the connection to StaffPad, makes me wonder if there will eventually be a way to purchase sample libraries from the likes of Spitfire, CineSamples, and Orchestral Tools.

These sampled instruments sound great, especially for the cost. For users who are used to working with thousands of dollars worth of sample libraries and massage MIDI data in a DAW, these samples may not be sufficient. However, for users like me who usually take whatever we can get with a minimal amount of fussing in a notation application, Muse Sounds represents a major leap forward for free. I think it’s particularly good in chamber settings where synthesized instruments often fall short.


Take a moment to listen to the demo above from the Muse Hub YouTube channel and hear for yourself. I have paid a lot more for sounds that are not this good. I don’t think it’s a stretch to say that Muse Sounds is comfortably the best first-party playback available in any notation application at any price.

In his post announcing the release of MuseScore 4, Martin Keary said, “Please note that we will be building additional tools, like automation and MIDI mapping in later releases.”

For those not wanting to use MuseSounds, there is the option of using a basic playback profile.


MuseScore has long had some of the most robust support for common accessibility features like screen readers, and MuseScore 4 extends its accessibility even further.

The color themes I mentioned above aren’t simply aesthetic. There is also a high-contrast mode (as well as each color being individually changeable) which can be a huge benefit to colorblind and low-vision users.

A new format option has also been added to the Export dialog to convert staff notation to braille music notation in the form of a standard BRF file, which can be read by braille embossers. In other major notation applications, as well as previous versions of MuseScore, this would have required exporting to MusicXML (already a lossy conversion) and then converting it using another application (another lossy step). I can’t vouch for the quality of the braille, as I don’t read braille, but I do see a lot of value to having this conversion contained within the notation application like this.

Saving and publishing

Not to be overlooked is the tighter integration with musescore.com, the rapidly expanding commercial side of the MuseScore project, where users can upload scores, share them, and obtain other scores. Within MuseScore 4 is an option to directly Save to cloud, so that you can publish your work on musescore.com. Like YouTube and other content-sharing sites, you can first set the visibility to Private and then later make it publicly available if you so choose.

Availability and system requirements

MuseScore 4 is available now from musescore.org.

Links are available for Windows, Mac, and Linux. System requirements for Windows are Windows 10 and higher; for Mac, it’s macOS 11.5 (Big Sur) or higher. Linux users need to click the “Download AppImage” button to install MuseScore, and also the text link “Muse Hub (for Muse Sounds)” directly below in order to get Muse Sounds.

The recommended method of installing MuseScore on Windows and Mac is to use the new Muse Hub; however, it is possible to separately download the MuseScore application, and links are provided.

MuseScore is available free of charge, as it has always been.

It’s worth noting that there are certain features in MuseScore 3 that, for the moment, are not available in MuseScore 4, according to Martin Keary: “There are other features that have not played nicely with our new systems at all, and which will need to be replaced in later releases, namely: the plug-in creator (which we want to rewrite completely as a priority), the score comparison tool and the ‘Documents side-by-side’ feature.”


I have often said in the past that the best and most important feature of MuseScore was it’s price: free. I meant that unironically. The price of the Big Three commercial applications is a major deterrent to many users. Being free actually is huge. Until now, I could not really say that it beat any of the Big Three in any other feature.

But now, I can honestly say that MuseScore has the best built-in audio playback. I have paid a lot of money for virtual instruments that do not sound as good as the free Muse Sounds. And it’s worth noting that these sounds are built on top of a completely rebuilt playback engine, so I suspect we’ll see more virtual instruments added to the Muse Sounds collection regularly. This is all in addition to the ability to bring your favorite VST3 instruments into the mix as well.

The layout and engraving features of MuseScore have long made it possible to make presentable scores, but it required a lot of manual tweaking and a lot of specialized domain knowledge that, most MuseScore users (and frankly most notation software users) simply have not had to learn. MuseScore 4’s updated collision avoidance, rhythm spacing, and other positioning algorithms have positioned it much closer to the commercial applications. In some cases, like the positioning of ties, slurs, and accidentals, MuseScore now does at least as well—if not better—compared to it’s competitors.

Even so, I still think it is a long way off from competing with the best automatic spacing and layout features of the commercial applications. Some of the quirkier default score settings remain unchanged. For example, the MuseScore projects I see in my teaching often end up with staves crunched far too close together. Vertical staff spacing in MuseScore 4 remains unchanged at 3.5 spaces, which is half the default in Sibelius (7 spaces) and nearly half the default in Dorico (6 spaces). While quibbles like these are extremely minor in light of the drastic engraving improvements in this release, they do add up. However, I trust the team at MuseScore and Muse Group to address these moving forward.

MuseScore 4 is a thoroughly impressive update, and one that promises great things for the future both of MuseScore and Muse Group.

Corrected on December 15, 2022 to remove inaccurate characterizations about a software hub as implemented by other companies.

  1. Bill

    Maybe now David Hearn can get back to work on StaffPad!

  2. Paul

    Thank you Martin Keary and crew for all the hard work!!

    Are there any plans to add a Dorico like midi window for extra tweakability?

    1. David MacDonald

      Thanks for reading!

      I don’t know if there are any particular plans for more MIDI control, but I would not be surprised to see some kind of new support for MIDI tweaking. I don’t know if a piano roll is in the cards for MuseScore. I do think that making meaningful use of VSTs would need a little more control than what is currently provided, but I’m open to the idea that Martin and the team may have a better idea. It could be along the lines of what we have seen in StaffPad or Graphical MIDI Tools for Sibelius, where you’re drawing automation curves on top of the staff itself, or maybe a whole new thing that I can’t imagine!

  3. Brian Smith

    Can’t easily find the words to say how much I value MuseScore. As an occasional user, I find it relatively easy to use and whenever I get stuck the response from the forum to any question is just amazing. There is a real sense of community with MuseScore and I’m always struck by how willing people are to help people like me who have very little idea about what they are doing. Patience is a virtue and you’ll see it if you ever venture onto the MuseScore Forum. Thank you MuseScore.

  4. iAnonGuy

    I feel like Finale’s days are numbered, especially if plug-in development picks up. They really are xo.peting well with SmartMusic/MakeMusic in the cloud and sharing space.

    Notion 6 is pretty much dead with this update, outside of Mobile. I don’t see why anyone would ever pay for it, except to get MusicXML into Studio One.

    I might install this just for creating Score Animations to upload to YouTube. Dorico is still next level for composition, but I have uninstalled Finale and it’s dead to me, moving forward.

    I think Sibelius is safe for now, and it doesn’t have the development issues that Finale has.

  5. Luis Acosta

    THIS. IS. AMAZING!!! You always knock the ball out of the park on your reviews, but what you reviewed is home run astounding. And I think you haven’t been more excited (and justifiably so) about improvements in a scoring program. Everything you said about the playback…spot on! As I listened, I had to call a specialist to reinstall my jaw. I’m going to download the whole kit-n-kaboodle. I really never expected anything to—and I’m just gonna say it—surpass NotePerformer 3 but NotePerformer 4. And I’m not even talking about price. The fact that it’s free makes it Nobel Peace Prize worthy. This opens up opportunities for those who can’t afford good playback sounds. And hopefully presents a challenge to other sound creators to lower their prices. Ok. maybe expecting too much. Thanks for bringing it to our attention. I had stopped checking on MuseScore after they changed their sharing policies, but now I’m going to have to have a second look.

    1. Luis Acosta

      After reading my post, it seems a bit gushy. But I really am excited about the playback.

    2. David MacDonald

      Thanks for reading and commenting, Luis! I hope you’re right that this set of samples is a bit of encouragement to the folks at the other platforms. As much as I love NotePerformer, it shouldn’t be _required_ to get reasonable-sounding mockups out of the Big Three. And NotePerformer is really smart and incredibly lightweight (even lighter than Muse Sounds), so I’m pretty excited to see what NP4 has in store as well.

  6. Ben Bals

    I’ve been a long time user of Musescore (3.6.2.).
    Now I’ve updated to MS4, but when I want to use East West Symphonic Choirs, I only get a small screen.
    Nothing happens and I can do anything with it.
    Maybe someone can help me, excuses for my bad English, I’m Dutch.

  7. Holly Koch

    I use the musescore software often and have never had any issues. BUT, I recently went to sign up for a free 7 day trial and was immediately charged. When I contacted muse score, they gave me the runaround and offered only a 25% refund. Now, I read online that it is a VERY common problem with their site. Bad business in my opinion.

    1. David MacDonald

      Hi Holly, It sounds like you may be getting MuseScore the scoring software with MuseScore.com, the score sharing service. MuseScore has always been completely free, and there is no requirement to connect to the MuseScore.com service at all.

  8. Filtgtr

    The improvements to the engraving are true improvements. However, the Linux version is basically cripple ware with no vst support. The windows version is so buggy that it is torture to use. The string sounds are pretty good but brass and woodwinds — not very good. The vocal sounds are completely unusable – so quiet that you must turn the volume to its highest level to even know that the vocals are there!

    You can get by using MU 4.0 as long as you only compose for strings. But if you write for jazz combo, concert or marching band, forget it. Incidentally, the propitiatory Muse-Sounds are incopatible with any other software. They will not work in any DAW ot package other than MU 4.0. If you like to polish your composition using a DAW, you are out of luck with 3.0.

    The most maddening thing about 4.0 is that it arbitrarily attempts to “humanize” music playback. It arbitrarily adds dynamic during playback and the composer has little control. MU 4.0 will make some notes and phrases loud and reduce other notes and phrases to inaudible volumes. This insane for any music software!!!!

    I have been using Musescore for approximately 10 years and was looking forward to the release of 4.0. I have never been so disappointed with a software release as I am with Musescore 4.0, With the exception of the notation improvements, 4.0 is a giant step backwards from 3.6. Free is nice, but functional tools are better. The only thing MU 4.0 is good for is to reformat the layout of compositions created in 3.6!

  9. Benny Rietveld

    Great article, thanks for posting it!
    Yep, I think they’re on the right track. I’m too entrenched in Sibelius (and not as smart as Phillip Rothman or David MacDonald), but my 19-year-old budding musician/composer (poor lad) uses it, I heard some mockups of some orchestration assignments and was really impressed, as were several of my music friends. And they seem to get the convergence that (hopefully) is coming where DAWs and notation programs (catchy acronym needed!) are far more integrated than they are now.
