Frequently asked questions

An online music education platform that helps instrumentalists grow through free sheet music, classical training content and AI performance feedback. The goal isn't just to finish one piece — it's to build the ability to play many more on your own.

We're currently building the service around the clarinet. Both the free sheet music and the AI performance review are in a testing phase focused on clarinet playing, and we plan to expand to other instruments afterwards.

Browsing the free sheet music and the piece detail pages is free and doesn't require an account. Copyrighted accompaniment scores and backing tracks can be purchased separately on Fullscore.

No. Anyone can browse and use the free sheet music list and the piece detail pages without logging in.

Use the “Buy accompaniment score · backing track” button on the piece detail page to purchase securely on Fullscore. Unlike the free parts, accompaniment scores and backing tracks are copyrighted paid content.

Yes. Let us know through the TalkTalk button at the bottom right of the page, or through the contact form. We use your requests to decide what to prepare first.

It analyses the fundamentals of your playing — pitch accuracy, rhythm accuracy, tempo consistency, note onset timing, and whether you played the piece through. It's currently in a testing phase, and we're refining its accuracy with clarinet playing.

The AI review doesn't replace a teacher's final judgement. Please use it as a support tool that helps you check your own playing as you practise.

Some features, such as joining a recording mission and saving results, require an account. Without one you can still try the AI performance review; saving results and earning points come together with member features.

You can sign up with just an email and password. After signing up, click the link in the verification email to complete verification, and then you can log in.

You earn points through activities such as taking part in recording missions, and we're preparing ways to spend them, including redeeming rewards. For safety, points are credited and deducted only through the server or an administrator's approval.

You can check your nickname, sign-up email, points balance, the number of missions you've joined, and your reward history. Your nickname, main instrument and playing level can be edited there — all optional.

You can do it yourself under “Delete account” at the bottom of My page. When you delete your account, personal data such as your email and nickname, along with any saved recordings, is destroyed immediately, and you can't log in with that account again. All of your points are lost and cannot be restored. Records of points spent and rewards redeemed are kept for a set period in a form that can't be traced back to you, as required by law, and then destroyed. See the Privacy Policy for details.

Press “Forgot your password?” on the login screen and enter the email you signed up with; we'll send a reset link. Set a new password from the link in the email, then log in again. For security, your old password is never stored or restored — you always set a new one.

Please check your spam or junk folder first. A dormant email account can't receive mail. Reactivate it with your email provider, then press “Resend verification email” on the login screen. Sometimes it still doesn't arrive after reactivating. That's because resending is blocked automatically once an address has bounced — we have to unblock it manually, so please contact us. If you're in a hurry, you're welcome to sign up with a different email.

Use the Naver TalkTalk button at the bottom right of the page for a live chat, or leave your enquiry on the contact page and we'll reply by email. You can contact us without an account.
