# Key Features

## AI-Powered Recognition

Using **"continuous play-through"** technology, even when you hit a wrong note, you won't get stuck — you can keep going and finish the entire piece. This approach focuses on building **rhythmic sense** and **fluency**.

**Built on deep neural networks, reimagining audio recognition!** Powered by a proprietary **real-time piano transcription model**, it captures every keystroke at the **millisecond level**.

- **AI Deep Learning Recognition**: Using **deep neural networks**, the system analyzes your performance data across **all dimensions**. Whether it's complex **chords** or subtle **dynamic changes**, everything is **accurately captured and reproduced**.
- **Multi-Dimensional Real-Time Feedback**: From **pitch accuracy** to **rhythmic precision**, the AI performs **millisecond-level verification** in real time. Like a meticulous practice partner, the moment you press a key, it delivers **professional assessments** of right and wrong notes and dynamics.

## Instant Feedback

Every note you play receives **real-time feedback**!

![](https://static.lianqinba.com/image/blog/9590f4741ad01a245215ba08edbfb880.png)

- **When you play correctly**: The note turns **green**! You can move on to the **next note**.
- **When you play incorrectly**: A voice prompt and the virtual keyboard will **show you the correct note name** and **its position on the keyboard**, so you can **try again**. Once you play it correctly, you can move on to the next note.

From **note-by-note correction** when first learning a piece to **smooth, flowing play-through** as you gain proficiency, the AI provides **millisecond-level responses** throughout.

- **Learning Phase — Challenge Mode (Note by Note)**: The feedback system works as **play it right and it lights up; play it wrong and it stops**. When tackling a **new piece**, the AI activates a strict **note-by-note verification mode**. Each correctly played note **lights up**, forcing you to **slow down and play accurately**. This **"instant blocking"** feedback mechanism helps you **completely eliminate wrong notes** while muscle memory is still forming.
- **Consolidation Phase — Trial Mode (Real-time Following)**: **The score follows along, highlights move in sync**. As you become more proficient, the AI switches to **real-time following** mode. The cursor tracks your playing like a shadow, closely matching your performance speed. At this stage, feedback no longer interrupts — instead, it provides **seamless assistance**, helping you immerse yourself in the **continuous flow of the music** and refine your **rhythm and musical expression**.

### 4.1 Magic Stories

We've created engaging Magic Stories to inspire you to keep practicing, adding **fun and a sense of purpose**!

Hidden within the **"Magic Challenge"** level map, you'll find **magical adventure stories**.

![](https://static.lianqinba.com/image/blog/bb40233c68f52adda36a95c1d79f1723.png)

Each story is divided into **3 parts**, tucked between the major levels. The beginning, middle, and ending **unlock in sequence** as you progress.

### 4.2 Magic Stars and Magic Stones

We hope that collecting and upgrading beautiful Magic Stars and Magic Stones will motivate you to **master every musical phrase**!

In **"Magic Challenge"** mode, completing each sub-level earns you **Magic Star rewards**.

In **"Magic Trial"** mode, finishing each trial level earns you **Advanced Magic Star rewards**. (These Advanced Magic Stars will play a big role later!)

![](https://static.lianqinba.com/image/blog/1d646973cc470d222e01be8acbf1b890.png)

At the **top** of the sub-level map, you can see the total **Magic Stars collected across all sub-levels** within that major level.

Once you reach a certain threshold, you'll earn a **Magic Stone**.

![](https://static.lianqinba.com/image/blog/71d20a714003a3db8c8ba410f607206f.png)

When all sub-levels within a major level are completed and you've earned **at least an S-rank Magic Stone**, the major level is considered complete and the next one unlocks.

Magic Stones come in **3 tiers**: S-rank Moonstone, SS-rank Cinnabar Stone, and SSS-rank Radiance Stone.

![](https://static.lianqinba.com/image/blog/9fa8169799379850d87906088b219da1.png)

As your Magic Star count grows, your Magic Stones **upgrade** too.

![](https://static.lianqinba.com/image/blog/3be27e0db59b574e75c4008fb4956296.png)

There's also the ultimate **Perfect Star challenge** waiting for you to unlock!

### 4.3 Magic Challenge

**"Magic Challenge"** focuses on **conquering new sheet music note by note**. Every note gets **real-time feedback** — you need to play each one correctly before moving on, making it ideal for **beginners building a solid foundation**.

![](https://static.lianqinba.com/image/blog/c56fc951f50357052f31a8822f283da3.png)

- **Progressive Level-Based Learning**: The piece is broken into **phrases** (major levels), which are further divided into manageable **segments** (sub-levels).
- **Three-Stage Practice Breakdown**: Follows a **right hand, left hand, hands together** sequence, creating a **progressive learning path**.

![](https://static.lianqinba.com/image/blog/da22903f2a8bcdea014b13419bb072a9.png)

**4.3.1 Standard Practice Path**

Enter the major level map, **swipe at the bottom** to select an unlocked major level (phrase), and tap **"Start"** to begin.

![](https://static.lianqinba.com/image/blog/aa844a03ed2ab3ec56a7f06e80fd0886.png)

Inside the sub-level map (segments), you can **freely choose any unlocked sub-level** to practice.

On the standard path, both major and sub-levels **must be unlocked in sequence** before you can proceed.

![](https://static.lianqinba.com/image/blog/2270d6dfc1dcef2f95f624263f35a3da.png)

Once inside a sub-level, play the **highlighted notes** on the piano.

Each sub-level requires **3 play-throughs** to complete. You can track your progress using the **progress bar at the top**.

![](https://static.lianqinba.com/image/blog/bc0011367c96b7d4686f08c463030285.png)

After completing one play-through, Xixi will mark the score with **different colors** based on your performance and award you **Magic Stars** as a reward!

If you achieve a **perfect score**, you can **pass the level immediately** and move on to the next sub-level without needing all 3 play-throughs.

![](https://static.lianqinba.com/image/blog/a2792198dc60c32ef49436df49b6698f.png)

**4.3.2 Skip-Ahead Path**

If you **don't want to go through the standard path** practicing one small segment at a time, you can scroll to the **far right of the sub-level map** and tap the purple **"Full Phrase" level**.

![](https://static.lianqinba.com/image/blog/55491971aaea9901e803a0d0b37512b4.png)

Tapping it triggers a **"Warp Challenge"**! If you succeed (your **performance meets the requirements**), it triggers **"Perfect Star Magic"**: all locked sub-levels **instantly unlock** and their **Magic Stars are filled to the max**!

![](https://static.lianqinba.com/image/blog/d1e34e113656f253a2520cf5bd6ff639.png)

During the challenge, if you feel your playing **isn't polished enough**, you can **exit the challenge at any time** and return to the sub-level map to continue **practicing along the standard path**.

![](https://static.lianqinba.com/image/blog/8b54a825ddbb9c1009979dc9eb3b42c0.png)

### 4.4 Magic Trial

**"Magic Trial"** emphasizes **full-section practice** and **free practice**.

It's best used after completing "Magic Challenge" to further **improve your performance skills**.

![](https://static.lianqinba.com/image/blog/252d5b2d1733372a16c49edb960830ce.png)

In "Magic Trial," all trial levels are **unlocked from the start**, and you can **freely choose** which **phrase** or **complete piece** you want to practice.

![](https://static.lianqinba.com/image/blog/416c7fb19318f1f549abe70cde26edde.png)

Inside a trial level, play the **highlighted notes** on the piano.

During play, **nothing will interrupt you** — a gradient highlight block simply **follows your performance**, moving along wherever you play.

![](https://static.lianqinba.com/image/blog/94d1ff57f7f5197beb2e6960b700c199.png)
