What Is an XR Piano Performance Assist App?

An XR piano performance assist app is an app that supports real-world piano playing through a headset. By leveraging AR and MR technology, it displays a visual guide in place of sheet music, showing in real time which key to press next.

The biggest feature is that you can play a song just by following the app’s guide, without needing the “ability to read sheet music” or “instruction from a teacher” that traditional piano practice required.

Hands-On Explanation by the Sigure Development Team

The app includes an auto-accompaniment function: when you practice the right hand, the left hand plays automatically, and vice versa — so you can enjoy practicing one hand at a time.

What Kind of XR Piano App Is Sigure?

Sigure is an XR piano game app compatible with the Meta Quest 3 / 3s. It’s designed to let you practice piano in a game-like way, and it’s used by a wide range of people — from complete beginners who can’t read sheet music to adults returning to piano after a long gap.

Simply connect your digital piano to the Meta Quest 3 / 3s with a MIDI cable, and performance assistance — with notes falling onto your real keyboard — begins immediately. No complicated setup is required; just connect the cable and launch the app to start practicing right away.

Sigure’s Main Performance Assist Features

Sigure includes several performance assist features specifically designed to help beginners avoid giving up.

FEATURE 01

Falling note guide

Just like a rhythm game, notes fall from above toward the keyboard. Your score increases based on Bad/Good/Great ratings and combo count, letting you keep practicing in a game-like way.

FEATURE 02

Auto-Accompaniment function

While you practice the right hand, the app automatically plays the left-hand part for you. This lets you focus on practicing one hand at a time and dramatically lowers the hurdle of combining both hands.

FEATURE 03

Stay Notes function

This feature pauses the notes and waits until you play the correct pitch. You don’t need to rush ahead, so you can practice carefully, confirming each note one at a time.

FEATURE 04

Tempo adjustment

You can freely change a song’s tempo. Slowing the tempo down reduces your playing speed, which means the notes fall more slowly too — letting beginners practice without feeling rushed.

FEATURE 05

Score and combo display

Your score and combo count are displayed in real time every time you play. The sense of accomplishment from playing better than last time helps you keep up your daily practice.

FEATURE 06

Additional song purchases

You can purchase additional songs individually (¥400–600 each) to practice whatever you’d like. Setting a favorite song as your goal makes it easier to stay motivated.

What You’ll Need to Get Started with Sigure

To experience XR piano performance assistance with Sigure, you’ll need the following three things.

A Message from the Sigure Development Team

We find that the people who think “piano seems too hard” are often the ones most surprised when they actually try Sigure.

Just press the keys following the notes, and the melody of a song you know starts to play. That moment of “I can actually play this!” becomes the biggest driving force behind continuing to practice.

First, set just one favorite song as your goal and give it a try.
