Trubadurček offers three distinct types of exercises, each targeting a different aspect of rhythmic skills:
- Rhythmic Dictation: Listen to a rhythm and write it down using a simplified music notation interface.
- Rhythmic Quiz: Listen and choose the correct rhythm from multiple options, designed for faster recognition and memory.
- Play the Rhythm: Read a rhythm from sheet music and tap it out accurately with the help of a metronome.
Each game includes gamified elements like points, timers, and limited attempts to encourage engagement and replayability.
The Trubadurček platform is built with a modern client-server architecture:
- Frontend: Built in React Native for cross-platform mobile and web compatibility.
- Backend: Powered by a Laravel-based REST API that handles exercise generation, result storage, and user management.
- Music rendering: Done using VexFlow, an open-source library for musical notation.
- Database: MySQL database for user profiles, results, and rhythm patterns.
This modular structure allows independent updates to the client or server, scalability, and easy maintenance.
The flow of the application is designed to be child-friendly and encourage regular practice:
- Log In / Register
- Select Game Type
- Choose Difficulty Level (out of 22 levels)
- Play the Game (Immediate feedback after each exercise)
- View Results and receive encouragement
- Optional Replay: Players are motivated to improve their score and reduce errors.
Each step was carefully tested with children during real-world experiments to ensure an optimal and enjoyable learning experience.
