What's New in Harmony

1.1.0

August 7, 2026

What's new in version 1.1.0 • Ear training: hear a note, interval, scale, or chord, then identify it. • Staff reading: read the concept straight off a staff (treble and bass clefs, key signatures, ledger lines) and play it back. • Microphone input: answer by singing or with your instrument. • MIDI input: plug in your keyboard (USB or Bluetooth) to play your answers. • Chord inversions in the exercises. • Choose the direction (ascending/descending) and playing style (harmonic/arpeggio) in the settings. • Unordered input for multi-note concepts. • Improved feedback: the expected notes are played back and highlighted on the keyboard. • New, smoother audio engine. Happy practicing!

Response from developer

Hi, and thank you so much for your feedback! You're absolutely right, and that's exactly why the new version 1.1.0, which just came out, now lets you choose the "by ear" question type to identify notes using sound only. We'd love for you to give this new version a try, and if it wins you over, feel free to update your review, it would help us a lot. Have a great day!
