Music Education Interface (MEI) is an educational app designed to support instrumental learning by combining visual, auditory, and interactive exercises. It helps students strengthen essential musical skills through structured practice and immediate feedback. Fingering Practice: The Fingering module helps learners connect musical notation, note names, pitch, and instrument fingerings. Each exercise follows a guided sequence: * Prepare during a measure of silence. * Listen to a reference note. * Play the note at the selected tempo. An instrument-specific fingering chart remains visible throughout the exercise, reinforcing the association between written notes and correct finger positions. Customize your practice by selecting: * Metronome tempo * Lowest note * Highest note This allows exercises to be tailored to beginners as well as more advanced players. Built-in Tuner: The integrated tuner provides real-time pitch detection, helping musicians develop accurate intonation and improve pitch awareness during daily practice. Supported instruments: Clarinet, Oboe & Trumpet Whether you are learning your first notes or reinforcing your technical foundations, MEI offers an intuitive and engaging way to practice more effectively.
