What's New in Pitch trainer

26.7.19

July 19, 2026

A new taiko drumming stage, "Mimic Taiko," arrives! Listen to the rhythm Sensei Murugai plays, then tap it right back — a call-and-response stage. From basic patterns to triple meter, triplets, sixteenths and syncopation: 5 categories and a generous 58 levels, all free to play. - Learn rhythm by feel with the listen, ready, mimic flow - The metronome pauses between questions so each one feels clearly separated - Added Italian language support Other improvements: - The "you are here" marker in each stage list now correctly points to the problem you played last - Minor bug fixes Thank you for using Harmonize!

User reviews

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.

Band Teacher

Crashing a lot in 2025.

Great app for teaching/hearing intonation.

Suggestion- 1. A way to set parameter of tones (most of the examples I listened to would be too high for students to discern) More low note intervals please! 2. Different voices that more closely resemble an instrument rather than a sine wave. 3. Ad-free version with paid upgrade. I'd pay $1-3 for the app if it had some of those tweaks.

Dislike- sometimes I get three stars for being +/- 5 cents whereas other examples its on two stars. What are the guidelines for scoring?
