Complete Music Trainer vs Interactive Music Theory Lab

Complete Music Trainer brings ear training, rhythm work, and music reading practice together in one interface for computer screens. Ear training offers more than 150 progressive drills in 11 types, covering intervals, chords, scales, melodic dictations, and chord progressions. Rhythm practice includes 252 progressive drills across five types and a dedicated polyrhythm section. Music reading provides 270 drills over seven clefs, including key-signature and mixed-clef practice. Users can make and save their own drills and training programs, then invite friends or students to participate. Recorded instrument sounds include grand piano, with additional sound banks for training sections. The service runs on the web, Windows, and macOS and includes progress tracking, harmony tools, rhythm practice, and basic notation tools. There is no free plan; a seven-day trial requires no credit card. The monthly subscription is €0.99 a month, the yearly subscription is €9.99 a year, and lifetime access is 19.99 EUR as a one-time payment. A free teacher account and Teacher Companion App support school-specific features, students, and licenses.

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.
