Field notes

The instructions describe a five-step workflow: grant microphone access, pluck one string, read the pitch, adjust the peg, then check the strings again. For ear tuning, the headstock diagram plays individual recorded reference notes. The page also gives exact standard-guitar frequencies at A4 = 440 Hz and notes that changing one string can affect the others.
