- Violin, viola, and cello players practicing intonation
- Worth noticing
- Notes the app cannot confidently distinguish are hatched gray instead of receiving a possibly misleading pitch judgment.
Field notes
The practice flow accepts scales or arpeggios, or a passage supplied as a PDF or photo, then places pitch judgments beneath notes and stacks takes to expose recurring misses. For major thirds, it offers a pure-third reference about 14 cents below piano equal temperament, with a setting to switch references; double- and triple-stop notes are assessed individually, while indeterminate notes are hatched gray. Players can set A from 440–444 Hz or let the app estimate it from a recording.
