“Music” Calculating musical notes

Perfect for learning notes and rests!

We have added content that can be used to learn musical notes and rests.

What kind of content?

  • A simple quiz format where a 〇 appears when you select the correct note or rest, and an ✖ appears when you select the wrong one.
  • There are two levels.
    • Level 1: No dots
    • Level 2: With dots (as of September 2021)

Recommended for people like this!

  • Lower grades who have not yet learned decimals and fractions
  • For those who want to develop a sense of rhythm and memorize the length of musical notes
  • People who want to grasp the concept of fractions such as “1/2” and “1/4” through music.

By repeatedly practicing the length of musical notes, it becomes easier to grasp the concept of “half of XX” and “half of that” when learning fractions later on.

I hope that repeating this exercise will help you to understand the concept of the length of notes.


🌟 Simple icons are used.
The designs are easy to see, making it intuitive to choose!

🌟 The icons displayed are different each time.
You can work on the same problem repeatedly without getting bored.

🌟 Large, easy-to-press buttons
Easy to press even on tablets and touch panels!

■ When is this ability useful?

✨ You will be able to “keep the rhythm correctly” in music class!
Once you can clearly visualize the length of notes and rests, you will be able to play in an ensemble and keep the rhythm perfectly!

✨ You will naturally develop a sense of fractions and decimals!
The concept that “this note is half a whole note” or “this is 1/4 of the length” will also help you learn arithmetic!

✨ Your listening and perception skills will improve, and your expression will become richer!
By noticing differences in rhythm, you will be able to add depth to your musical expression!

development materials

This is a draft of the screen (UI, etc.) created in the early stages of content development.

■ Behind-the-scenes stories of development

Compared to the preliminary UI design created in the early stages of content development…
It’s interesting to note that the buttons have been implemented almost unchanged, with only a slight change in shape (laughs).

I hope to continue adding more content that will be useful for learning rhythm in the future.
