musictheory.net review

musictheory.net is the simplest free place to start. Its exercises run in a browser with no download, and the ear training section covers keyboard ear training, where you hear a note and press the matching piano key, plus note, interval, scale and chord ear training. The same site offers identification and construction drills on the staff, keyboard and fretboard, so students can connect what they hear with what they read. Teachers get two useful tools: an Exercise Customizer that creates a permanent link to a set exercise, and a Code Checker that validates verification codes students submit after practice. Everything is free, and the site asks users who find it helpful to buy its Tenuto app. The limits are depth and structure: there are no courses, no progress path and no rhythm or dictation drills, so it works best as a supplement or for a quick warm-up.
