Store description excerpt

Do the three notes of your chord really sound at the same time? Or does one finger arrive just a little late? You often cannot hear it yourself, but it makes your playing sound muddy instead of crisp. ChordScore connects to your MIDI piano and measures the exact moment every key is struck. For each chord you get the spread in milliseconds, a score out of 100, and a clear verdict: perfect, tight, good, loose or sloppy. MEASURE - Millisecond-accurate MIDI timestamps, far more precise than your ear - Automatic chord detection: notes played together are grouped for you - Live feedback while you play, with a timeline showing every note - Chord recognition, from triads to thirteenth chords - See how hard you press each note, with the dynamics from pp to ff - Optional analysis of how evenly you release the chord TRACK YOUR PROGRESS - Record sessions and keep every measurement - Charts: spread over time, distribution, timing per voice - Automatic insights such as "on average you play the middle note 6.2 ms late" - Progress across all your sessions - Export any session as CSV PRACTICE - Randomly generated target chords: triads, seventh chords, inversions and wide voicings - Highlighted on an on-screen keyboard - Checks both the correct notes and how evenly you strike them - Streaks and accuracy to keep you going CONNECT - USB (camera adapter or USB-C) or Bluetooth MIDI - Virtual MIDI port so other apps can send to ChordScore - No piano at hand? Use the built-in demo keyboard PRIVATE BY DESIGN Everything stays on your device. No account, no ads, no tracking, no analytics. Requires a MIDI keyboard or digital piano for real measurements.
