What's New in Pitch trainer

26.10.17

October 18, 2026

■ Redesigned stage menus The category cards in every stage are new. At a glance you can see the number, an illustration, your stars, your average offset (± cents) and where you are now. In Double Stop, Chords and more, you can preview the interval right on the card, and the cards for Rhythm, Scales, Arpeggios and Drone show and play what each exercise is like. You can reopen the stage explanation at any time from the "?" on the category screen. ■ Double Stop question list The question list is easier to read. Questions you haven't unlocked yet now show just their number, faded. ■ How-to videos "How-to videos" in Settings is now a list, and new videos are marked NEW. You can also open the how-to video for a stage from its explanation. (Videos are in English.) ■ Moon Ebifurya now wears a space helmet. ■ Also - Bizenkurage joins Sight Reading, and the category names are clearer - The Goldfish Scoop card now shows a pond - With Bluetooth or AirPlay, the screen now tells you the sound may be delayed - Weekly ranking ranks are now based on final standings - Fixed battery drain while the Home screen was open - Fixed the Back button text being cut off in longer languages

吹部です!

ずっと苦手だったピッチの合わせができるようになってきて嬉しいです!!!様々な知識が手に入って暇な時間もより一層部活のことに集中できるようになりました!
音階はドイツ音名でやっているのですが、InFやInE♭はできないのでしょうか?

Response from developer

レビューをありがとうございます。苦手だったピッチ合わせができるようになってきたとのこと、とても嬉しいです。 in F・in E♭ の表記は、現在は実音(in C)のみですが、移調楽器向けの音名表示に対応する予定です。ドイツ音名のまま、ホルンやサックスの読みで表示できるようにします。準備ができ次第、アップデートでお届けします。 部活での練習に役立てていただけて光栄です。

和音のステージ

バージョンアップで単音が鳴るようになりましたが、以前のように和音だけが鳴るような設定はないでしょうか。

Response from developer

ご意見ありがとうございます。分かりにくくなってしまい申し訳ありません。 お手本ボタン(緑)を押したときは、以前と同じように和音がそのまま鳴るように直しました。 問題が始まるときの自動再生は、構成音を1音ずつ聴いてから重ねる形のままにしています。 この変更はまだ配信前で、次のアップデートに入ります。 今しばらくお待ちください。

TERRIFIC for ANY MUSICIAN!

I’ve pretty much had this app since early 2020, and I’ve loved it ever since. I really love the additions that this app has added on especially the rhythm games, new pitch games, tuner, metronome, etc. I REALLY love this app and I can’t wait to see what can be furthermore done with this app and its possibilities.

Response from developer

Thank you for sticking with Harmonize since 2020 — that means a lot. We're still building: the next update brings a new practice stage and a number of refinements to the existing ones. It hasn't shipped yet, so please give it a little time. If there's something you'd like to see in Harmonize, we'd love to hear it.

FAQ

What is this app for?

This app is designed to help users develop perfect and relative pitch through ear training exercises. It specifically focuses on the principles of just intonation, teaching users to identify and match harmonic intervals by ear.

How does the app teach just intonation?

The app plays two sounds simultaneously and requires users to match them based on just intonation principles, which differ from equal temperament. Users adjust the tone until they achieve a clear, beat-less sound, indicating a just interval.

Who would benefit from using this app?

This app is beneficial for a wide range of individuals, including those learning chords in just intonation, singers aiming for better karaoke performance, and members of brass bands and orchestras who require precise intonation.

Is this app free to use?

The application is free to download and use, but it does offer in-app purchases. This means certain features or content may require an additional purchase to access.

What is the reference tone used in the app?

The reference tone used for chords in this application is A=442 Hz. This standard tuning frequency ensures consistency in the exercises and helps users calibrate their ear training.
