Chord Studio: Piano

Chord Studio is a practice app designed to help complete beginners who have not yet learned chords accompany freely by reading chord symbols.

By working through Beginner, Intermediate, and Advanced Courses in order, you can build your skills step by step: keyboard and chord names, inversions, scales, chord progressions, two-hand playing, quarter-note and eighth-note patterns, broken chords, arpeggios, and accompaniment patterns. Questions you do not pass are automatically returned for review.

Basic Practice includes ten named scale types in all 12 tonics. Genre Practice offers representative progressions and scales for J-pop, Rock/J-rock, Anime/Game/Vocaloid, K-pop, Western Pop, Classical, Hip-hop/Rap, Jazz, Enka/Kayōkyoku, and R&B/Soul.
