Chord Progression Lab 앱 분석 (10월 9일)

Chord Progression Lab turns music theory into a sandbox. Pick a key. Pick a style. Listen. Tweak. Export. That's the whole loop — and it's surprisingly addictive whether you're a songwriter looking for your next progression, a producer hunting for a starting MIDI, a music student studying voice leading, or just a curious listener who wants to know what a Phrygian dominant actually sounds like. 25+ music-theory approaches, from familiar to far-out: • Pop, Doo-Wop, Pachelbel's Canon, Circle of Fifths • 12-Bar Blues and Jazz • Rock and Punk power-chord progressions • Epic Minor and Andalusian cadences • Indian Raga (Bhairav), Arabic Maqam (Hijaz), East Asian Gōng pentatonic • Japanese Hirajōshi, Indonesian Gamelan (Slendro) • Klezmer Freygish, Flamenco Phrygian, Celtic Mixolydian, Slavic minor • Bulgarian 7/8 Balkan, West African Highlife • Bossa Nova, Reggae, Hawaiian slack key • Avant-Garde quartal stacks and tone clusters All 12 keys. Transpose any progression — instantly. Dissonance dial. Great for ear-training, jazz studies, or just hearing how a vanilla I–V–vi–IV mutates when you add tension. Tempo control. Drag from a slow 40 BPM crawl to a 200 BPM sprint. Each style starts at a tempo that fits the genre. See it as you hear it. A piano keyboard lights up with the active chord tones in real time, and the chord sequence scrolls along showing Roman numerals and the actual chord name in the current key. Export MIDI. One tap saves a standard MIDI file you can drop into any DAW — and the share sheet sends it anywhere: AirDrop, Files, email, Messages. No accounts. No ads. No tracking. No internet required. Everything runs on-device with a built-in synthesizer. Whether you're studying theory, writing a song, prototyping a beat, or just curious what a Bulgarian 7/8 progression sounds like — Chord Progression Lab gets you from idea to audio in two taps.
