Piano Trainer

Piano Trainer is an open-source desktop application designed to help users memorize piano scales and chords. It serves as an interactive reference manual for music theory, providing a structured environment for practicing keyboard layouts and the circle of fifths. The software is available for multiple platforms and can be installed via binaries or as a Flatpak for Linux distributions, ensuring compatibility across different operating systems.

Users interact with the program through a virtual keyboard or by connecting a MIDI controller for a more authentic experience. The application focuses on repetition and testing through various practice modes, allowing students of music to verify their knowledge of musical intervals and structures. By providing immediate feedback on input, the tool helps learners identify mistakes in their fingerings or theoretical understanding of a specific key signature.

Key features

• MIDI controller compatibility
• Home row keyboard input
• Interactive scale practice
• Interactive chord practice
• Interactive circle of fifths practice
• Quiz mode for theory testing
• Hard mode for increased difficulty
• Shuffle mode for randomized practice

The application is built using Rust and the Tauri framework, which allows it to maintain a small footprint while providing cross-platform support. It integrates React for the piano interface and utilizes MIDI libraries to handle external hardware input. The software is intended for piano students and music theory learners who require a tool for drilling scales and chords. Because it is built with Tauri, the application leverages web technologies for the frontend while maintaining the performance of a native system application.

For those who wish to modify the software, the project supports local development through the Tauri CLI and Yarn. The codebase is structured to allow contributions to the development branch, with stable builds merged into the main branch. This architecture makes it accessible for developers who want to add new scales or refine the quiz logic.

Piano Trainer positions itself as a specialized utility for music education, focusing on the mechanical and theoretical aspects of piano practice.
