Use the correct strings
Install a nylon classical-guitar set in the tension recommended for the instrument. Do not substitute ordinary steel acoustic strings: a classical guitar is not designed for steel-string tension. Confirm whether your set has tie ends, ball ends, or special manufacturer instructions before beginning.
Change one string at a time or remove the set?
Changing one at a time preserves tension and provides a visual reference for the knots and roller direction. Removing all six makes cleaning easier. Either can work on a healthy conventional instrument, but follow the manufacturer’s directions for unusual bridges or sensitive instruments.
Remove an old string safely
- Loosen the tuner until the string is completely slack.
- Unwind it from the headstock roller.
- Carefully release the bridge knot without scraping the soundboard.
- Remove the string and wipe the exposed area.
Protect the guitar top from loose ends. Nylon treble strings can snap back, while wound bass strings can leave sharp wire tips.
Tie the string at the bridge
Pass the string through the bridge hole, leaving a short tail. Bring the tail back around the main length and secure it with the appropriate wrap so the final bend rests behind the tie block rather than on its upper edge. Smooth treble strings often need additional locking wraps compared with textured wound basses.
Attach the headstock end
Thread the string through the correct roller and leave manageable slack. Begin winding so the wraps progress neatly and the string follows a clean path toward its nut slot. Keep the string away from neighboring rollers and sharp slot edges.
Watch the roller rather than memorizing clockwise or counterclockwise. Winding more string raises pitch; releasing string lowers it. See Which Way Do You Turn Guitar Tuning Pegs?
Bring nylon strings to pitch gradually
Tune in stages across the entire set. Standard classical tuning is E A D G B E. Nylon strings settle substantially, so the first string will often be flat again by the time the sixth is close. Several passes are normal.
How to settle the new set
Gently lift each string a small distance from the fingerboard at several points, then retune. Avoid hard pulling near the bridge tie. Continue until another gentle pass produces less pitch loss. Expect to retune frequently through the first several practice sessions.
When should you trim the ends?
Leave enough tail at both ends to confirm the bridge ties and roller wraps are secure. Once the set has held tension and nothing is slipping, trim cautiously. Avoid leaving sharp ends that can scratch the headstock or soundboard.
Common classical-string mistakes
- Using steel strings on a nylon-string instrument
- Allowing the bridge tail to rest where it can slip forward
- Using too few locking wraps on a smooth treble string
- Crossing wraps on the headstock roller
- Cutting tails before confirming the knot
- Assuming initial tuning drift means the tuner is broken
Final checks
Confirm every string passes through its proper nut slot, every bridge tie is stable, and no tail touches the vibrating string. Tune with the online tuner, play for several minutes, and tune again. For standard pitches and slotted-headstock details, read the classical guitar tuning guide.
