Practice by listening
Hear a scale, then identify a separate mystery note by ear.
Product project · Music education
A more approachable way to practice relative pitch - recognizing notes by ear.

PitchMaster is designed for intermediate to advanced musicians who already understand piano keys, scales, and intervals. It helps them practice identifying a note’s place in a scale by ear. If you’re new to music theory, it’s completely normal for the exercise to feel unfamiliar—the app assumes that foundation.
New to music theory?
In 2025, I took an online course on playing piano by ear. Our instructor told us the best way to practice relative pitch was to have a friend play individual notes from a scale, while we identified each note’s place in that scale by ear.
I lived alone, so I couldn’t easily practice that way. This got me thinking - what about the other musicians who didn’t have someone nearby to play the notes, or who simply wanted to practice independently.
I looked online for a music app designed to accomplish that: establish the scale, play a mystery note, and let the user answer. I couldn’t find a single one, so I built PitchMaster.

Hear a scale, then identify a separate mystery note by ear.
A wrong guess doesn’t immediately reveal the answer; players can learn from it and try again.
Missed degrees help guide more focused practice.
Building PitchMaster has helped me turn a personal interest into a focused product experience. I’m continuing to refine the practice loop, feedback, and coaching as I learn what helps people improve.
