Measured against the target notes of the chosen tuning, not against the semitone grid. A string may therefore be a whole tone out and is still recognised as itself. The pitch is computed in the browser — no sound leaves your device.
Anotona does this for you
Photograph a page of sheet music or play the melody — Anotona finds the key, engraves the notes and transposes them into any other. Free.
See AnotonaEvery note on this page is computed, not typed in — following the rule that also makes F# major spell its seventh degree E#, not F.
