As Peg and Scroll, we are quite in-tune with tuning procedures.
Instrument Tuning
If possible, your teacher should be present when learning how to tune your instrument. Tune gently and with care.
Most instruments have Fine Tuners, which makes tuning strings easier.
Tightening the screw increases the string’s tension.
Fine tuners work much like bass machine tuning, in the sense that turning a gear adjusts string tension.
Some tail pieces have fine tuners built-in.
If a string needs a small adjustment, then always use the fine tuners. Tuning with the pegs can be tricky.
Remember this import Peg Tuning Rule:
ALWAYS APPROACH THE PITCH FROM BELOW!
Simply put, if you over tighten a string it will break!
All strings are stretched to the proper frequency.
Each string is designed to withstand the proper string tension needed to bring the open string to pitch.
Most professional players check pitch with electronic tuners, securing accurate and well-callibrated tuning.
As your musical ear develops, you can tune the instrument by comparing the strings to one another.
