In their own words
Interactive Music Theory Lab
Interactive Music Theory Lab is a free web app for learning and applying music theory. Chord Lab offers an interactive chord builder, chord library, piano keyboard, staff notation, voicings, and inversions. Scale Explorer covers more than 100 scales and maps their patterns on piano and fretboard. Theory Academy provides interactive lessons, guided tutorials, exercises, and subjects ranging from intervals to voice leading. Composition Studio lets users arrange progressions and song sections by drag and drop, receive theory-based suggestions, and export MIDI or PDF. The interface also lists MIDI and MusicXML import and export, along with PDF and audio export. Users can upload MP3, WAV, OGG, M4A, or FLAC files for chord-progression detection; clear recordings work better than complex mixes. The service requires no account and includes progress tracking. It offers guidance rather than writing songs for users, and the maker notes that bugs exist.
