Mobile technologies coupled with the power of artificial intelligence offer many affordances for educators and learners alike. This paper presents a case of a music mobile app, Harmonia-on-the-Go, created for the purpose of teaching and learning an area in music theory that deals with chord grammar. As a kind of personal tutoring tool, the app generates automated feedback that reinforces the harmonic theory to be learnt. Student users can practise creating chord progressions anytime, anywhere, with immediate feedback given. If registered as a user, they can seek supplementary asynchronous feedback from the music teacher; learning analytics will also be generated for their self-monitoring of their own learning. For the teacher, the app reduces mundane marking but more invaluably, it frees up time for them to focus on monitoring students' learning as reflected in the learning analytics generated. They can in turn offer remedial teaching if necessary. The "Consult" function in the app also gives the teacher an additional platform, outside of class, to address students' questions.The article presents some brief observations from the pilot testing of the app, conducted with fifty high school students. It ends by articulating how this app can potentially transform the teaching and learning of music theory.
