What's New in Pitch trainer

26.9.15

September 15, 2026

■ New stage: Drone Tune phrases note by note over a low note that never stops, the way a bagpipe does. Your guide is Macfurya, the Scottish branch of the Ebifurya clan. - Categories are organized by tonic (the drone note). Within a category the drone stays put while you work through shifts, chords and the bagpipe scale - The first 5 problems on C are free; the rest unlock with PRO - If an alarm or a call interrupts, the drone resumes when you come back ■ New sound: Bagpipe The bagpipe chanter made for the Drone stage is now available in Sound Settings for every stage, double stops included. Its beating is easy to hear. Tap the instrument image in Sound Settings to audition it. ■ Also - With transposition (in Bb / Eb / F / A), tonic names now show "in F" etc. so you can tell they are written pitch - Fixed note-name chips being squashed and unreadable - Minor fixes and stability improvements

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.

It is great and has helped me but….

I like this app so much and it helps me with pitch althoughI do wish the user could determine the range the pitch is in, Personally I wish I could choose the range of the bass guitar.

Response from developer

Thank you so much — it means a lot that Harmonize has been helping you. And what a wonderful idea. Choosing your own range to practice in, like the bass guitar’s, is exactly the kind of thing that would make this ear training richer. I’d love to look into adding it. Thank you for sharing it.

楽しくてためになる

音を上下させて、調和させるときの、濁りがだんだんと透き通っていくような感じが好きです。アンサンブルのための音程取りのトレーニングにもぴったりです。

Response from developer

うれしいご感想をありがとうございます。濁りが少しずつ澄んでいく、あの瞬間を楽しんでいただけて何よりです。アンサンブルの音程取りにも、ぜひ使ってみてください。

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.
