Metaphysical tuning Method ① : Telephone busy signal alignment method
Step:
Dial any number (listen to the busy signal "beep --")
The busy signal frequency is approximately 440Hz (standard A tone).
Adjust the pitch of the open fifth string to be consistent with the busy signal
Scientific basis: Global telecommunications system A tone calibration is uniform (within an error of ±1Hz)
🔥 Violent tuning method ② : Overtone resonance technique
Operation:
Play the 6th string 5th harmonic vs. 5th string 7th harmonic
The two notes should be on exactly the same frequency. If a "wavy sound" occurs, fine-tune the fifth string until the resonance disappears
Applicable scenarios: Quick calibration of relative pitch accuracy during outdoor performances
🎸 Jianghu Scam: The fatal flaw of tuning APP
Limitations of mobile phone microphones:
Poor low-frequency recognition (causing the 6th string to never be adjusted accurately)
Environmental noise interference (subway station tuning ≈ suicide)
Hardware Party solution:
Clip-type tuner (Recommended Snark SN-5, ￥50)
Acoustic tuner (Boss TU-12EX, stage level)
🤯 Advanced player Easter Egg: Use the "Wolf tone" to work backward and tune
Phenomenon: Some taste tones suddenly become hoarse → wolf-like notes
Cool move:
Find the Wolf note on the 6th string (usually near the 7th fret)
Adjust the string length (move the bridge) to make the Wolf sound appear in less commonly used tones
The other strings are adjusted synchronously in a five-degree relationship
Effect: Obtain the exclusive "dessert spot" tone!
