DJ Bach is a unique multimedia application designed for Android users, focusing on music creation through algorithmic composition. Utilizing the Tonamic method, it generates dynamic musical pieces based on tension and surprise derived from pitch dissonance values. The app offers three main control methods: touch controls for manual play, motion control using device orientation, and a premium EEG headband link that connects to a Muse EEG device. Each method allows users to create music that is responsive to their input and emotional state, making it an engaging tool for both casual users and music enthusiasts.

The touch controls function as a 2D keypad, enabling users to trigger levels of tension and surprise rather than specific notes. Motion control allows for an immersive experience where users can conduct music through movement, while the EEG headband feature links the music generation to the user's emotional metrics. DJ Bach provides a personalized experience, producing multiple melodic lines and adjustable accompaniment, making it an innovative choice for anyone interested in music and emotional expression.
