Store description excerpt
「Chord Tone Trainer is a music theory app that helps you learn diatonic chords naturally by playing with birds. ■ Step 1: Learn the stacked-thirds order Birds sing along a conveyor belt in stacked-thirds order (C→E→G→B→D→F→A). When a bird turns into a "?", tap its note on the fretboard below to answer. Repeat the pattern and the stacked-thirds order will stick with you. ■ Step 2: Learn the notes of each diatonic chord Chicks in a nest each show their scale degree. Tap the note matching the hopping chick's degree on the fretboard to feed it. Master the notes of all seven diatonic chords while playing. ■ Who is this for - Anyone who wants to improvise theoretically on guitar or keyboard - Anyone who struggles to instantly recall chord tones - Anyone who wants to learn music theory through play, not dry textbooks ■ Why choose this app - One-time purchase only. No extra in-app purchases, no ads. ■ From the developer I built this app because I wanted it myself, while teaching myself guitar. I kept opening theory books to memorize chord tones, but it never really stuck. So instead of forcing myself to study, I aimed for something you could just play with in a spare moment — and before you know it, your grasp of the fretboard and chords has quietly improved. Available in both English and Japanese. *This app is optimized exclusively for iPhone.
