Tuning Tips
Use a quiet space
Background noise degrades microphone accuracy.
Tune up from below
Tuning up from a lower pitch is more stable than coming down from above.
Re-check all strings
Changing one string's tension can affect neighboring strings.
Use reference tones
Combine with Tone Generator for a pure reference tone.
