teoria review

teoria is a free website built by José Rodríguez Alvira to support his courses at the Conservatory of Music of Puerto Rico, and it has been online since January 1997. It suits college and conservatory students because its exercises go beyond intervals and chords into melodic dictation, two voice and four voice dictation, harmonic progressions, rhythmic dictation using patterns and harmonic analysis of short excerpts. Many exercises accept answers from a MIDI keyboard in Chrome, Firefox, Edge or Opera, and signing in lets you save scores and see your practice time over the last 30 days. Tutorials and reference pages explain the theory behind each drill. The site has removed all advertising and runs on donations. Its design is dated, it is less pleasant on a phone, and it does not lead beginners through a course, so newcomers should start with an app and add teoria for dictation work.
