Lock In

Lock In was created by a working musician and private instructor to help their own students better understand intonation, hear pitch relationships, and feel more confident when they play.

Now you can build stronger note recognition, refine your intonation, and play with greater confidence using Lock In—a focused practice tool designed for developing musicians.

Lock In provides clear visual pitch feedback that helps you recognize notes, understand whether you are sharp or flat, and make precise adjustments in real time. Its simple graphical interface keeps practice approachable, allowing you to focus on listening and improving without unnecessary distractions.

A built-in intonation game turns pitch training into an engaging challenge, reinforcing note recognition while helping you develop confidence, consistency, and a more reliable ear.

• Clear real-time pitch and intonation feedback

• Support for transposing instruments
