Description by Koji Hasegawa (from the App Store)
Chordalyst Piano helps you learn piano chords, scales, and accompaniment from chord symbols and beautifully engraved scores. Practice on the on-screen keyboard or with a Bluetooth/USB MIDI keyboard.

Course Practice contains 61 sections—12 Beginner, 14 Intermediate, and 35 Advanced—covering keyboard and chord names, inversions, scales, progressions, two-hand playing, quarter- and eighth-note patterns, broken chords, arpeggios, and accompaniment patterns. Waltz, Octave, and Ballad patterns are included. Questions you do not pass return automatically for review.

Basic Practice lets you focus on chords, inversions, ten named scale types in all 12 tonics, progressions, two-hand playing, rhythm patterns, broken chords, arpeggios, and accompaniment. Broken-chord choices include Bass then Upper Chord, Alberti, Waltz, Octave, and Ballad patterns. 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.

Song Practice includes nine pieces grouped by difficulty: Ode to Joy, Pachelbel's Canon, WTC Book I Prelude No. 1, Für Elise, Gymnopédie No. 1, The Entertainer, Turkish March, Clair de Lune, and Maple Leaf Rag. Auto Advance plays the melody from each correctly performed chord up to the next chord point.

Import your own Standard MIDI Format 0 or 1 file, including directly from Files or another compatible app. Chordalyst Piano converts notes, durations, rests, chords, independent voices, beams, ties, and mid-song key, meter, and tempo changes into a MusicXML piano grand staff. If the MIDI contains no chord markers, chord names are inferred from its notes. Use piano playback, a gold position cursor, automatic scrolling, and separate melody, chord, and metronome volumes. Automatic conversion and chord inference may not reproduce every choice in a source score.

Import only MIDI files you created or are authorized or otherwise legally permitted to use. Saving, engraving, playing, or exporting does not transfer copyright or other rights; confirm any additional permissions required before publishing, distributing, or sharing the material.
