«INFORMATION SYSTEM FOR CATALOGUING AND ADAPTIVE DISPLAY OF MUSICAL DATA ON THE ANDROID PLATFORM»

This paper describes the development and implementation of a mobile information
system designed for cataloguing, analyzing, and adaptively displaying musical data on the Android
platform. The developed application integrates an AI-based assistant via API, providing personalized
recommendations to users during guitar learning and practice. The system is implemented using modern
Android development technologies such as Kotlin, Jetpack Compose, and Android SDK. The article
presents the system architecture, user interface structure, and the key functional modules, including a
tuner, metronome, chord catalog, and a teacher marketplace. Functional analysis and user scenarios for
mobile music learning are discussed. The project’s significance for self-education and music pedagogy is
highlighted.
