Absolute Pitch Checker

■ Tips for improving
Absolute pitch is a memorization game, so you can easily memorize it by using the following memorization techniques.
・ Input and output
・ Distributed learning
・ Difficulty is divided
■ Input
Remember the sound in association with the songs you listen to often. For example, "C" is the beginning sound of the Brahms string quintet, "C#" is the beginning sound of X JAPAN SCARS, "D" is the beginning sound of Dvorak Symphony No. 8, and "D#" is the beginning sound of X JAPAN DAHLIA, "E" is the sound of Papparapa's pippirapee, "F" is the sound of Puprapupoo's popporape, and so on. If you listen to it many times, you will remember it naturally. It's OK if you listen about 60 million times.
■ Output [Important]
Test if you were able to memorize. This can be done with the app. I made this app to do this.
■ Distributed learning
Do this app every day. You only have to do it for a short time. You don't have to do it for a long time. You can do it while brushing your teeth. This will allow you to remember for a long time.
■ Difficulty is divided
At first, you only have to do Lv01 with the app. Lv01 is very easy because only "C" and "D" are asked. Gradually raise the level. Finally, finish with Lv12 (ultra-ultra hyper devil MAX level).
With that feeling, it's perfect after a few months.
