Keystrike vs Excel Art

Build a piano practice habit you can hear. Keystrike brings graded lessons, sight-reading and real pieces together in an iPad-first workspace. KNOW WHAT TO PRACTICE NEXT Follow a daily plan that brings together your next lesson and focused work on difficult passages. Track completed lessons, retained skills and practice time. Progress means music learned, not points collected. PLAY, READ AND LISTEN • Follow graded lessons from your first notes through more advanced skills. • Practice sight-reading, rhythm, ear training, scales and chords. • Read engraved sheet music or follow falling notes. • Slow pieces down, practice hands separately and repeat sections. • Import your own MIDI files and turn them into playable sheet music. • Record practice and export MIDI. CHOOSE YOUR INSTRUMENT Use a compatible USB or Bluetooth MIDI keyboard for precise note input, or start with the on-screen piano. Acoustic mode records your piano performance for on-device analysis after you finish. Recognition varies with your piano and room; MIDI is recommended for precise chord and two-hand tracking.
