The Art of Tuning
Before electronic tuners, musicians relied on tuning forks (invented in 1711 by John Shore) and their ears to tune instruments. The standard concert pitch of A=440Hz was adopted internationally in 1955.
Electronic tuners emerged in the 1970s, revolutionizing how musicians tune their instruments. Today, chromatic tuners can detect any note and show exactly how sharp or flat you are.
Modern tuning apps use advanced algorithms like autocorrelation and FFT (Fast Fourier Transform) to analyze pitch with remarkable accuracy—often within 1 cent of the true frequency.
Tuning Tips
Quiet Environment
Tune in a quiet space for accurate pitch detection.
Tune Up to Pitch
Always tune up to the note, not down, for better stability.
Check All Strings
After tuning, recheck strings as tension changes can affect others.
New Strings Stretch
New strings need time to settle. Retune frequently at first.
Use Reference Tones
Play reference tones to train your ear for the correct pitch.
Temperature Matters
Instruments can go out of tune with temperature changes.
