Synthesia Piano Review (2026): Fun Piano Game or Fast Track to Nowhere?

If you've ever searched YouTube for a piano tutorial, you've seen Synthesia: coloured notes falling onto a keyboard, like Guitar Hero for piano. Synthesia is also the app behind those videos, and you can use it to learn songs on your own keyboard. I've used it with students who were scared of sheet music, and I've seen where it helps and where it holds people back. This review covers what the Synthesia piano app does, what it costs in 2026, how to set it up, and whether it can really teach you piano.

3.9Best for learning songs from MIDI files

My verdict on Synthesia

“The fastest way I know to get a song under your fingers, and the easiest way to never learn to read.”

Verdict: Fun, flexible and cheap for a lifetime licence. Use it to learn the songs you love, and turn on the sheet music so it doesn't become a crutch.

What is Synthesia?

Synthesia is a piano learning game that shows music as falling notes. Each note is a coloured block that drops toward an on-screen keyboard. When it reaches the keys, you play it. If you connect a digital piano or MIDI keyboard, Synthesia listens to what you play and can wait for you, score you and track your progress.

Some people call it the Synthesia app, others the Synthesia piano game, Synthesia music or Synthesia piano software. They all mean the same program. It runs on Windows, Mac, iPad and Android, and it's made by a small company, Synthesia LLC. (It has nothing to do with Synthesia, the AI video company at synthesia.io. Same name, different product.)

Synthesia has been around longer than most piano apps. Developer Nicholas Piegdon released it in 2006 as "Piano Hero". In 2007, Activision asked for a name change to avoid confusion with Guitar Hero, a name contest picked "Synthesia", and the Mac version came out. The paid Learning Pack, with sheet music, followed in 2008. Synthesia came to the iPad in 2012, opened its Music Store in 2013 and arrived on Android tablets in 2014.

Synthesia's own history page says it became "the most popular way to produce piano tutorial videos online" by 2011. That's why the falling-notes look is everywhere on YouTube. When people search "Synthesia piano", they often mean those videos, not the app itself.

How does Synthesia work?

Synthesia works with standard MIDI files (and, since version 10.8, MusicXML files). A MIDI file stores which notes are played, when and for how long. Synthesia turns that information into falling blocks:

• Which key: the block lines up with the key to play.
• When: play it as the block touches the top of the keyboard.
• How long: a longer block means a longer note.
• Which hand: by default the left hand is blue and the right hand is green.
• Which finger: a number on the block is a finger hint, from 1 (thumb) to 5 (little finger), if the song includes them.

Without a keyboard, you can watch and listen, or play on your computer's typing keyboard using Synthesia's virtual piano mapping. With a MIDI keyboard connected, Synthesia "listens to your playing and helps you learn any song," as its About page puts it. That's when the app becomes really useful.

One thing Synthesia can't do: hear an acoustic piano. Every input it describes is MIDI, by USB, a MIDI interface or Bluetooth MIDI. I found no microphone mode in its official material, so you need a digital piano or MIDI keyboard for any feedback.

Synthesia features

Three practice modes

Synthesia scores you in three ways:

• Melody practice: "Synthesia waits for you to play the correct note before moving on." Coloured dots appear on the keys you should play. This is where every song should start.
• Rhythm practice: you can slow the tempo, but now the timing counts against the beat.
• Recital: the full performance, scored on notes, rhythm and note lengths at the song's speed.

Each song earns up to 100 points. You can only reach 100 by playing the song with both hands, almost flawlessly, several times, in all three modes. It's a simple system, but it gives you a reason to come back to a piece instead of moving on too soon.

Practice tools

• Hands separately: choose the left or right hand, and Synthesia plays the other part for you.
• Speed control: slow any song down with the + and − buttons.
• Jump and loop: click the timeline to go to any bar and loop a section.
• Labels: show finger numbers, note names (C D E), fixed-do or movable-do solfège, or scale degrees on the keys and notes.
• Sheet music: show notation above the falling notes, or switch off the falling notes and read sheet music only.
• Key lights: on keyboards with lighted keys, Synthesia lights up the next notes in melody practice.
• Free Play and recording: play freely, see chord names, and record up to six tracks with the built-in multi-track recorder (unlocked version).

Songs: 150+ included, plus any MIDI file

Synthesia includes 150+ songs. Its real strength is that it plays any MIDI or MusicXML file you can find or create, so the song library is effectively unlimited. Synthesia also runs its own Music Store with licensed arrangements of popular songs. Most songs I saw there cost $0.99 to $2.99, with themed bundles too. If you edit songs, the free Synthesia Metadata Editor lets you add finger hints and hand parts.

A word of warning from experience: MIDI files you find online vary a lot in quality. Some are badly timed or don't split the hands, which makes practice frustrating. Licensed Music Store songs, or well-made files from trusted arrangers, are worth it.

Synthesia vs sheet music

This is the big question for anyone learning with Synthesia, so here is the same melody both ways:

Falling notes are easier on day one. You see which key, when and for how long, with no reading at all. Sheet music carries more information: the beat and bar lines, the key signature, phrasing, dynamics and pedalling. It also works on any piano, from any book, without a screen.

The good news is that you don't have to choose. Synthesia can show sheet music and falling notes at the same time (press F2 on a computer, or use the gear menu). Read the staff, and let the falling notes check you. As you get better, shrink the falling notes or turn them off completely.

Is Synthesia good for learning piano?

Synthesia is good for learning songs, but it isn't a complete way to learn piano. It's excellent at getting the right notes under your fingers and keeping you motivated. It doesn't teach the skills that make you independent at the piano.

What it does well:

• It gets you playing real songs fast. For many adults, that's what keeps them practising past the first month.
• It practises the right way. Slow tempos, hands separately and looping hard bars are exactly what I ask students to do.
• It's honest about mistakes. Melody practice won't move on until you play the right note.

Where it falls short:

• Reading. If you only follow the falling notes, you'll be lost in front of a book or a piano without a screen.
• Theory. There's no explanation of chords, scales or keys. You learn what to play, not why.
• Technique. No app sees tension, wrist height or posture. Bad habits are easy to build alone.
• Memory. It's easy to learn to follow lights rather than learn the music. Test yourself by turning the notes off.

So is Synthesia good for beginners? Yes, as part of a plan. I'd pair it with something that builds reading and theory, such as a method book, a course like Pianoforall, an app like Piano Marvel, or a teacher. My guide to teaching yourself piano shows how to put that together, and the piano basics guide covers the keyboard from scratch.

How to learn a song with Synthesia (a teacher's routine)

Most people press play and try to keep up. That's the slowest way to learn. Here is the routine I give students:

1. One hand at a time. Start in melody practice with the right hand. Synthesia waits for each note, so there's no rush.
2. Then the other hand. Same bars, left hand, until both feel easy.
3. Hands together, slowly. Melody practice with both hands, then raise the speed bit by bit.
4. Rhythm practice. Now the beat counts. Keep the tempo low and steady rather than fast and messy.
5. Turn on sheet music. Read the staff while the falling notes check you.
6. Recital. Play it through at full speed and go for your 100 points.

Work in short sections. Use the timeline to loop four bars at a time instead of starting from the top every time. Ten focused minutes on the hard bars beat half an hour of run-throughs.

How much does Synthesia cost?

Synthesia is a free download with a one-time unlock. On October 31, 2026, the unlock key cost $29 on sale (regular price $39) on synthesia.app. In Synthesia's words, it's "NOT a subscription. All future updates are included with your one-time purchase."

What the free version includes: more than 20 of the 150+ included songs with every feature, the first 20 seconds of any other song, and all MIDI device features, including key lights. That makes it a perfect way to test your keyboard setup before you pay.

What the unlock adds: all 150+ songs, any MIDI file at full length, and the multi-track recorder in Free Play.

Where to buy it matters:

• From synthesia.app: one key works "everywhere: PC, Mac, iPad, and Android simultaneously," and for your whole family.
• Inside the iPad app: cheaper (Apple lists it as "Play Any Song" for $7.99), but it only works on iPads on that Apple account.
• Inside the Android app: works only on Android devices on that Google account, and Google's Family Library doesn't cover it.

Refunds: for website purchases, Synthesia offers refunds "with no questions asked" for up to 180 days with PayPal, or 120 days with other payment methods. In-app purchases are refunded through Apple or Google.

Is Synthesia worth the money?

For most people, yes. $29 once is less than many apps charge for a single month, and it covers every device you own. The value depends on what you want, though. If you want a structured course from zero, a subscription app or a course will teach you more. If you want to learn specific songs and you have a keyboard, Synthesia is hard to beat for the price.

How to connect a keyboard to Synthesia

Synthesia needs a MIDI connection to hear you. Most keyboards made in the last 15 years or so have a USB port for this, often labelled "USB to Host".

1. PC or Mac: connect the keyboard's USB port to the computer with a USB cable (usually USB-B on the keyboard).
2. iPad: use a USB-C cable on USB-C iPads, or Apple's camera adapter on Lightning iPads.
3. Android tablet or Chromebook: use a USB OTG adapter or a USB-C cable. Chromebooks need ChromeOS 65 or later for USB MIDI.
4. Older keyboards with round 5-pin MIDI ports: use a MIDI-to-USB interface.
5. Open Synthesia, play a few keys, and check that it responds. If it doesn't, check the keyboard is selected in Synthesia's music device settings.

Synthesia has supported Windows 10 Bluetooth MIDI since 2017, but a cable is still the most reliable option. Don't have a keyboard yet? Synthesia works with any MIDI keyboard. For real practice I recommend one with full-size, weighted keys. Start with my picks for the best beginner pianos, such as the Yamaha P-145.

Light-up keyboards: Synthesia supports keyboards with key lights. It highlights the next notes in melody practice right on the keys, which can help beginners find chords faster.

Synthesia platforms and system requirements

• Windows: Windows 7 (64-bit) and later. Synthesia says it runs on "any PC or Mac made in the last 10 years" with OpenGL 2.0 graphics.
• Mac: macOS 10.9 and later, with Apple silicon support since version 10.8.
• iPad: iPadOS 9.3 or later. The App Store also lists Apple Vision Pro. There is no iPhone version.
• Android: Android 5.0 and later, from Google Play or as an APK. Synthesia says it's best on a tablet-sized screen.
• Chromebook: compatible Chromebooks with Google Play.

One honest caveat: Synthesia isn't updated often. The last major desktop version, 10.9, came out on December 21, 2022, and the iPad app was last updated in February 2023. It still works well, but don't expect new features soon.

What other users say

Synthesia has huge reach: more than 10 million downloads on Google Play, with a 3.9 out of 5 rating from about 93,500 reviews. On the iPad App Store it also rates 3.9 out of 5, from about 3,600 ratings (both checked October 2026). Those scores sit below some newer apps, partly because many people download it expecting a full free app and then hit the unlock. My advice: try the 20+ free songs first, then decide.

Synthesia alternatives

If Synthesia isn't quite right, here is how it compares with the apps I recommend most:

• Simply Piano: a guided, game-style path for total beginners on phones and tablets.
• Flowkey: popular songs with videos of real hands and sheet music.
• Piano Marvel: the best choice if you want to learn to read music properly.
• PianoVision: falling notes in mixed reality, landing on your real keys, on a Meta Quest headset.
• Pianoforall: a one-time course that teaches chords, rhythm and playing by ear.

My pick to pair with Synthesia: Pianoforall

Synthesia teaches you songs. Pianoforall teaches you how music works: chords, rhythm patterns and how to play songs by ear from a chord chart. It's a course of video lessons built into ebooks, with a 7-day free trial and then a one-time payment of $49. Together they cover most of what Synthesia leaves out.

Who should use Synthesia?

Synthesia is for you if you want to learn specific songs quickly, sheet music puts you off, you already love YouTube piano tutorials, or you have a teacher and want a fun practice tool between lessons.

Choose something else if you want a full course from zero, fluent sight-reading, chords and theory, or feedback on technique. And if you only have an acoustic piano without MIDI, Synthesia can't hear you at all.

My verdict

Synthesia is one of the best practice tools you can buy for $29. It turns any song into something you can learn, it waits for you, it scores you honestly, and one purchase covers every device you own. For motivation and repertoire, it's excellent.

Just don't mistake it for a teacher. On its own, Synthesia trains you to follow notes. Turn on the sheet music, use the routine above, and pair it with something that teaches reading and theory. Do that, and Synthesia can speed up your learning a lot. My score: 3.9 out of 5.

Synthesia FAQ

Is Synthesia free?

Synthesia is free to download and try. The free version lets you play more than 20 of the 150+ included songs with every feature, plus the first 20 seconds of any other song. To play everything, you buy a one-time unlock key, which cost $29 (regular price $39) in October 2026.

How much does Synthesia cost?

An unlock key from synthesia.app is a one-time payment, not a subscription: $29 on sale, normally $39. It works on PC, Mac, iPad and Android at the same time. In-app unlocks on iPad or Android cost less but only work on that store's devices.

Is Synthesia good for learning piano?

Synthesia is good for learning songs, practising hands separately and building finger coordination. It doesn't teach reading, theory or technique, so it works best alongside a method book, a course or a teacher.

Is Synthesia a game?

Yes. Synthesia describes itself as "a game that can help you learn how to play the piano using falling notes." It started in 2006 as "Piano Hero", inspired by rhythm games like Guitar Hero.

Does Synthesia teach you to read sheet music?

Not by itself. Synthesia can show sheet music above the falling notes, or sheet music only, so you can practise reading. But it doesn't explain how notation works. Turn sheet music on and gradually rely on it more than the falling notes.

Do I need a keyboard for Synthesia?

No, you can watch songs or play on your computer's typing keyboard. But to get feedback, Synthesia needs a digital piano or MIDI keyboard connected by USB, a MIDI interface or Bluetooth MIDI.

Can Synthesia hear an acoustic piano?

No. Synthesia listens through MIDI only, and I found no microphone mode in its official material. An acoustic piano without MIDI can't send Synthesia any notes.

How do I connect my keyboard to Synthesia?

Connect the keyboard's USB port to your computer, iPad or Android device with a USB cable (and an adapter if needed). Older keyboards with 5-pin MIDI ports need a MIDI-to-USB interface. Then open Synthesia and play a few notes to check it responds.

Can I use my own MIDI files in Synthesia?

Yes. Synthesia plays any standard MIDI file, and MusicXML files since version 10.8. The free version plays the first 20 seconds of outside songs; the unlocked version plays them in full.

Does Synthesia work on iPhone?

No. Synthesia's iOS app is for iPad (iPadOS 9.3 or later), and the App Store also lists Apple Vision Pro. It also runs on Windows, Mac, Android tablets and compatible Chromebooks.

What is the latest version of Synthesia?

The latest version is Synthesia 10.9, released on December 21, 2022, with improvements to Free Play and labels. The iPad app is on version 10.9.2, from February 2023.

Is Synthesia the same as the Synthesia AI video app?

No. Synthesia the piano game is made by Synthesia LLC (synthesia.app). Synthesia the AI video platform (synthesia.io) is an unrelated company.
