I do not think Synthesia is completely bad for learning piano. I think it is useful for one specific thing: helping you learn the notes of a song quickly.
That is exactly why so many beginners like it. I liked it too at first.
When I was struggling with sheet music, Synthesia felt like a relief. Instead of staring at a page of symbols that looked more like a trap than a song, I could just follow the falling bars and press the keys. It made piano feel easier and more immediate.
And to be fair, it does work for that.
You can learn songs with Synthesia. You can memorize hand movements. You can get a piece under your fingers faster than if you tried to read every note from sheet music right away.
But learning a few songs is not the same thing as learning piano.
What Synthesia actually teaches
The limitation of Synthesia is that it gives you only a small part of the musical information.
Mostly, it shows you when a note starts, when it ends, and which key to press. That is helpful, but piano playing is much bigger than that.
When I started paying more attention, I realized I was missing a lot of what makes music actually sound musical. Sheet music includes things like:
- dynamics
- phrasing
- articulation
- accents
- slurs
- musical structure
Those details are not just decoration. They shape how the piece should sound and feel.
If I only follow a piano roll, I can copy the notes, but I am not really learning the full language of the music. I am learning the outline, not the whole picture.
Why that becomes a problem
The biggest issue is not that Synthesia is useless. The issue is that it can keep you dependent on it.
You can get pretty good at copying visual patterns without getting better at reading actual music. Then every new piece depends on finding another video or another piano roll. You are still borrowing the song from a tutorial instead of being able to open real sheet music and work through it yourself.
That is why I think Synthesia is a bit of a shortcut. It can help you learn a couple of songs, maybe even many songs, but it does not really train the broader skill of being a pianist.
And that distinction matters.
I did not just want to memorize songs. I wanted to understand what I was playing and become more independent over time.
Why sheet music matters
Sheet music gives a much more complete view of the piece. It shows rhythm, structure, expression, and how both hands relate to each other on the page. It does not only tell you what notes happen. It tells you how the music is written.
The problem, of course, is that sheet music can feel slow and frustrating at first. That was my problem too. I wanted to learn properly, but I did not want piano practice to feel like homework with extra suffering.
So the real question for me was not whether to use piano rolls or sheet music.
It was: is there a way to use both, without getting stuck in the weaknesses of either one?
Why SunScore solves the gap
What I like about SunScore is that it fills that gap in a way that feels much more natural.
Instead of replacing sheet music with a piano roll, it lets me use both at the same time. I can upload the score I actually want to play, whether it is a photo, scan, PDF, or digital file, and then practice with the original notation still visible inside the player.
That changed a lot for me.
I still get the visual clarity of the piano roll and keyboard guidance, but I am also learning how the piece looks on real sheet music while I practice. So I am not choosing between “fast but shallow” and “proper but painfully slow.” I get a bridge between the two.
That is the part I wish I had earlier.
SunScore input is not MIDI files, but the sheet itself, so all the music information is kept.
So, is Synthesia bad for learning piano?
I would say this: Synthesia is not bad if you use it as a starting point, but it is limited if you use it as your whole method.
It can help you learn songs. It can help you memorize. It can make piano feel less intimidating in the beginning. But on its own, it does not give you enough musical information, and it does not really help you grow into reading and understanding music.
If your goal is just to copy a few pieces, Synthesia can do that.
If your goal is to actually become a more complete pianist, you need sheet music too.
