Customized Melodis to Recall Your Precious Memories

A professional music arranger will edit the customized music box melody for your important moments, such as wedding proposal, and anniversary/birthday gift.

Just 1 Click, the Music Box Will Play Your Song!

If you have purchased the customized arrangement, we will upload the song you have selected before the music box is shipped. When the recipient opens the music box and plugs in the power, they simply need to press the knob to instantly play the song you carefully selected!

Add a Personal Touch with a Customized Song Cover!

Once the music box is connected to the app, this customized playlist will also appear in the playlist list. You can use these fields to add more personal touches to this exclusive gift.

You can specify: Playlist cover image, playlist title, and music box name as well as the account avatar and melody’s background displayed during playback. Feel free to get creative and make it a unique gift!

Why do I need to request a melody to be edited by a music arranger?

The music box has very distinctive qualities. At the same time, its limitations have become part of its charm.

When arranging for the music box, it’s essential to consider its range, tempo, and number of simultaneous notes. To learn more about how arrangers unleash creativity with these limitations, feel free to read this article.

Adapting a full-length piece of music into a music box version not only gives the song a fresh and crystal-clear style but also challenges the arranger to apply the art of “subtraction” during the simplification process. Transforming rich layers of sound into the refined purity of a music box is the core charm of music box arrangement and a true testament to the arranger’s skill.

How Long Will It Take to Complete the Customized Melody Composing Service?

▪︎The average production time for a customized arrangement is estimated to be 5-7 business days or more. This estimate does not include weekends and holidays, so we appreciate your patience.

▪︎The song will only be uploaded to the music box for shipment after it has been completed and approved by you.

▪︎If you need the gift urgently, we offer an option to ship the music box first and provide the song later. The song file and upload instructions will be sent to you for manual uploading.

The Steps to Complete Your Customized Melody Composing

1. Select the number of songs you wish to order on this product page, add them to your cart, and complete the payment.

2. Once we receive your order, we will contact you via email to fill out the song form. You can also click the button below to submit your song information directly.

3. After receiving the song form, we will forward it to the arranger to schedule the arrangement.
The arranger will aim to preserve the melody and rhythm of the song, while adapting it to fit within the music box’s range by transposing and rearranging the accompaniment, ensuring the essence of the song is captured within the music box’s capabilities.

4. Once the arranger completes the arrangement, we will email you a preview audio file for your approval and offer two opportunities for minor adjustments. Any modifications beyond two revisions or significant changes will be discussed with you, and an additional modification fee will be quoted based on the situation.

5. After your approval, our customer service team will upload the song to the music box that has not yet been shipped. The arranger will listen to the song to confirm its accuracy. When you receive the music box, simply plug it in and press the knob to start playing your chosen song!

We will also provide you with the MIDI file of the song, so you can modify the arrangement or use the audio on other devices in the future.

Let Customized Music Box Melodies Speak for My Heart

Daniel (Singapore)

I used the Muro Box to propose to her.

I decided to propose to her in a clearing in the woods. Instead of a speech, I decided I would present my sentiments in song.

Live music has a special and unique quality, but I do not play any instruments — the Muro Box was the perfect companion for me.

T. was my girlfriend and now wife. Music is one of T’s talents and a key part of our relationship (we enjoy singing together). She has always had a soft spot for music boxes. When I discovered the Muro Box, I knew that it would be a wonderful gift for her.

The moment I knew that I absolutely had to get the Muro Box was when I opened up the app and played a melody that I knew (River flows in you by Yiruma) on Twitch.

Hearing my melodies played live by the Muro Box was eye-opening in a way that the YouTube recordings were not. Live music just strikes you differently, even if it’s 7,701 miles away.

Deep Gratitude for My Wife Embedded in the Music Box

K. Gold (U.S.A)

My wife loves music boxes but is always frugal and doesn’t spend much on herself. One day, while I was playing the piano, I discovered that she particularly loves a piano piece called “Ballade Pour Adeline.” I thought that finding a music box that plays this song would be the perfect gift for her!

For ten years, I couldn’t find such a music box until I came across Muro Box. The expression on my wife’s face when she received this gift was unforgettable!

It was truly wonderful to find Muro Box!

My father sends endless love and wishes to my ears through the music box.

Emily (U.S.A)

My dad purchased the Muro Box for me as a wedding present for my wedding in June 2019. The Muro Box came ready to play “You’ll Be in My Heart” by Phil Collins, our special song since I was a little girl. He always played Phil Collins’ CD in the car; my dad, sister, and I would sing along, driving with the windows down in the summertime. We had every word memorized!

Represent My Childhood Memories for My Son through the Music Box

Nicolas (France)

I actually don’t remember much about the plot of the movie *My Neighbor Totoro*, but my memories from before watching it are still vivid: the cold, snowy winter days, red noses from the chill, hot tea, the line of people passing fresh-baked bread, the steam coming from my brother’s mouth, and the excited, noisy shouts of dozens of children. All of this took place in front of that small theater, waiting and anticipating to see what kind of creature the cat-bear was.

I still remember humming the Totoro song with my sister as we left the theater, getting into the car and screaming like we were riding the Catbus.

This is why I am so sincerely grateful to you—Muro Box team—for allowing me to relive such pure and wonderful memories. For me, this is also a gift for my one-year-old son, giving him this song in a version that is uniquely his.

Weaving Memories with Melodies

Muro Box Arranger-Hung Yin Liu

The sense of accomplishment I get from arranging music is knowing my clients get emotional when receiving their requested melodies and feel their dreams have come true. The satisfaction is unparalleled when customers let me know how they were all in tears when watching the Muro Box playing those meaningful melodies.

Sometimes, I receive melody requests that are not suitable for Muro Box, but once I realize the touching stories behind them, I feel that I had to do something to make Muro Box play such meaningful melodies.

For example, an American professor with late-stage cancer has designated the song “Every breath you take” to remember the love and romance he had with his wife in the younger years. He also would like to use this song to celebrate his wife’s upcoming birthday.

This song was not easy to compose, as I hummed it over and over, using key-shifting and all the arranging techniques that I know to find the best way to present this melody on the Muro Box. I was sleepless that night because I kept thinking about how to make sure this melody can be represented well like the original song.

Finally, the professor shared how he and his wife were in tears of joy when hearing Muro Box playing this melody. I’m glad that my hard work is deeply appreciated, and I can contribute to preserve their unique and precious memories. Are you curious about how I connected with the app-controlled music box and helped fulfill dreams for customers from all over the world through the customized arrangement process? Feel free to read my music box arrangement story.

What’s more, after accumulating experience with hundreds of music box arrangements, I have compiled relevant techniques and shared them in this article.

How long does it take to complete a customized arrangement?

The average production time for a customized arrangement is estimated to be 5-7 business days or more. This estimate does not include weekends and holidays, so we appreciate your patience.

About the range and speed limitations of music box arrangements

(1)Muro Box will only read a single track of the MIDI file.

(2)N20: C3-A5, on a diatonic scale
N40: F2-C6 on a chromatic scale (excluding F#2, G#2, A#2, C#3)).
“C3 = Middle C (261.6Hz)”

(3)Playing Speed Limitations: Under a BPM of 120, the minimum unit for continuous single notes is an eighth note (four notes per second).

(4)N20: Maximum simultaneous notes = 7 (up to seven notes can be played at the same time).

About song length and pricing

We base the pricing on a song length of 2 minutes as the standard. If the song is shorter than 2 minutes, we will charge for 2 minutes of arrangement due to personnel costs.

You can specify the 2-minute section you’d like in the arrangement form or leave it to our arranger to suggest an appropriate segment. Typically, extracting 2 minutes from a song will cover the main verse and chorus.

If you would like to arrange a section longer than 2 minutes, please note it in the remarks section of the arrangement form, and we will have the arranger assess it and provide a quote.

How to evaluate if a song can be arranged for a music box version?

Please fill out the form, and once we receive it, we will forward it to the arranger for evaluation. We will contact you via email with the evaluation results.

Any modifications beyond two revisions or significant changes will be discussed with you, and an additional modification fee will be quoted based on the situation.

The Music Box I’ve Always Dreamed Of - I am a theremin performer and composer.
As the theremin is a monophonic instrument, it often requires accompaniment—typically piano or guitar. However, I’ve always been especially fond of pairing it with music boxes.

Over the years, I’ve explored many types, including disc music boxes and punched-roll models. Yet I continued to long for a high-precision, auto-playing music box that could handle more complex performances.

The Muro Box-N40 turned out to be exactly that. It offers beautiful tone, excellent stability, and precise expression through advanced control. Even real-time performance using a MIDI keyboard is possible, with virtually no latency.

I genuinely believe this is a revolutionary instrument.

In my latest video, I perform Debussy’s Rêverie as a duet with the Muro Box-N40 and theremin. The result was everything I had hoped for.

From now on, I look forward to continuing my musical journey with this remarkable partner.

分享美妙旋律，傳遞幸福時光 - 收到這只音樂盒時當下的驚奇和幸福,，至今我還未找到適切的描述來表達內心真實的感受。我一向是個很珍重情誼的人，當送禮人將這只音樂盒放在桌上，兩個有著38年情誼的中年女生手忙腳亂地在手機上download app, account login, Bluetooth connect … 當清脆無暇的旋律從音樂盒流瀉出來時，我們相視笑著，宛如18歳的女生啊，很是滿足。這是無疑是當代的科技研發和創作。
過去的音樂盒，我們因為曲目和造型設計而入手、擁有和收藏它，且每個音樂盒隨著時間和人承載了不同的故事。隨著科技的進步，如今，將這只音樂盒插上電源，接下來的聆聽體驗或許是當年一個簡單的發條木盒子或是曾經擁有過旋轉芭蕾舞小女孩的音樂盒的你從未有過的想像吧? 如同當我們拿到第一部行動電話時，可曾想過如今smartphone的存在?

音樂盒外觀簡潔且充滿細節的設計，有著安定厚實的觸感，不論是送禮收禮，甚至入手給自己，在客製化的選項配搭過程更像是享受當代充滿溫度的一杯特調。

我很喜歡它，也傳遞、分享這個美妙的音樂盒給其他人。期待不懂作曲的自己，有一天也能編上一段屬於自己的旋律藉由這只音樂盒奏出。

Hidden musical gem in the middle of authentic Taipei - Came here with my mate on 6/30/2025 — though they’re quite a small company they pack a punch. Unique in that they’re the first company in the world to make an automated instrument that plays music acoustically in your own home, and you don’t need to buy a player piano that’s hundreds of times the price to do it! You can either come here to see the magic live in action or order their music box online to play live music in your home! The people here are really nice and they write a card to everyone who visits as a token of gratitude.

30年来の夢が叶いました。(A Dream 30 Years in the Making Has Come True.) - 私はオルゴールの音色が大好きで約30年くらい前に初めてオルゴールの曲を作曲し、それから何曲か続けて作りました。
midi音源で自分の曲を再生した時、嬉しさもありましたが当時は現在のリアルな音源やvstもなく「いつか、本物のオルゴールで鳴らしてみたい」という夢を持つようになりました。

それから何年か経ち手回しオルゴールを購入しましたが、当時は白鍵のみで大幅にアレンジが必要な上、長い楽曲には不向きだったり、本物のオルゴールのように自動演奏できないためリラックスして聞くことができませんでした。

2018年にN20のNewsを見ましたが、半音階が使えず購入を断念しました。
理由は、半音階が使えなかったからです。

作曲をする方なら理解できると思いますが作曲を続けていると、どうしても転調や半音階を使ったり、様々なキーで作りたくなります。
N20に半音階がどうしても欲しいと思って、muro boxのプロジェクトを見ていたらN40のプロトタイプの話題があり「出たら必ず買う！」と心に決めていました。

そして、2025年6月…
ついに、私は夢を叶えることができました。
学生だった自分が結婚して家族に、その時作曲した曲を本物のオルゴールで聞かせることができました。

酷鳩の皆さん本当にありがとうございました！

============
I’ve loved the sound of music boxes for as long as I can remember. About 30 years ago, I composed my first piece for a music box, and after that, I wrote several more.

When I played back my compositions using MIDI sound sources, I was happy, but at the time, there were no realistic VST instruments like we have today. I had a dream: “Someday, I want to hear my music played on a real music box.”

Years later, I purchased a hand-cranked music box. However, it only supported white keys and required major rearrangements. It wasn’t suitable for long pieces, and since it couldn’t play automatically like a real music box, I couldn’t listen to it in a relaxed manner.

Then, in 2018, I came across the news about the N20 model. However, I gave up on buying it since it couldn’t play chromatic notes. That was the key reason I passed on it.

Those who compose music can understand this—once you continue writing music, you want to modulate keys, use chromaticism, and compose in various keys.

I really wanted an N20 that could handle chromatic notes. While reading about the Muro Box project, I saw news about a prototype of the N40. I immediately thought, “I’ll definitely buy it when it comes out!” and made up my mind.

And then, in June 2025… At last, my dream came true.

I, who had once been just a student, got married, started a family—and I was finally able to play the pieces I composed back then on a real music box for my loved ones.

Thank you so much to everyone at Cooju!

A Brilliant Device That Brings Music to Life! - Hello,
I'm truly delighted to be using the Muro Box.

I ordered it from South Korea in November, and after nearly six months of use, I wanted to share my experience. I first discovered the Muro Box through its development videos on YouTube, and I was deeply moved by the dedication and passion that went into creating it.

The mechanism is incredibly ingenious—truly admirable from an engineering perspective.

Using the Muro Box app, I played the intro of one of my favorite game OSTs: "To Me, My Childhood" from Lost Ark.

Thank you for creating such an amazing instrument.

Amazing Team!!! - I love my Muro Box N20, it works perfectly on its own, with the included phone app, and I can use midi from my external instruments to control it with no problems. As well I got the resonator box, and I can confirm that it is worth it! The music box sounds louder and the sound really fills the whole room. I would highly recommend these music boxes to everyone.

A beautiful music box - The muro box is one of the best creations of modern times. I found out about Muro Box after searching to create a custom music box, but was a taken aback by the cost of creating a custom movement, and the work required to design something beautiful. When I saw Muro Box, I immediately chose it as the product I wanted. Modernized, sleek, and still respects the traditional beauty of mechanical movements. I am very happy with the product.

無意間完成了她的夢想 - 我是位聲援著名為『凛々咲』虛擬VT的粉絲。會發現MuroBox也是我無意間起的念頭，時間點是在2022/11月底時候，為了慶祝凛々咲的生日企劃而準備禮物。
凛々咲本身也是為創作詞曲的音樂家，當時聽著音樂盒聲音時想到『如果有著一個音樂盒能播放著她的原創曲的話一定很讚』的想法。
於是開始在網路上尋找關於音樂盒訂做的部分，找了許多資料後也間接找到了MuroBox相關訊息
看了以後我很確定我找到我要的答案了，便開始準備禮物事項。
由於生日企畫籌備時間有點趕，一度還擔心會趕不上不過還好感謝團隊的幫忙順利的幫我把禮物給趕工出來也很謝謝劉虹吟老師幫忙編曲凛々咲的原創曲。
最後也把禮物送到凛々咲的手上，在直播中也提到她曾經去過音樂盒博物館去參觀，也夢想有一天希望有她自己音樂的音樂盒，
而我在無意間完成了她的夢想。
