About
Chordio is an interactive music composition and theory app for producers, composers, teachers, and learners on iOS and macOS. Its workspaces cover composition, scales, modes, sheet music, music theory, and lessons, with a library of more than 40 scales. Connect a USB, MIDI, or Bluetooth MIDI keyboard and Chordio identifies played chords, naming them on the grand staff in real time. Harmony Explorer finds matching scales and suggests diatonic chords, borrowed chords, secondary dominants, and tritone substitutions. Users can send progressions to Logic Pro, Ableton Live, FL Studio, and other DAWs as MIDI, or import MIDI chords for re-harmonization. The Sheet Music workspace supports adjustable tempo, looping, separate-hand practice, transposition, and PDF printing. Lesson Packs allow pieces to be played in different keys and tempos. The free download includes built-in sounds, an on-screen keyboard, every workspace, and MIDI chord detection. Full Unlock costs $14.99 USD once and covers Mac, iPad, and Vision Pro with lifetime updates; the iPhone version is separate.
