Replacing the frets (Pardeh) on a Tar or Setar is an essential maintenance task that ensures the instrument plays in tune and Replacing the Frets (Pardeh) on a Tar or Setar: A Practical, Accurate Guide

Replacing the frets — Pardeh — on a Tar or Setar is an essential part of maintaining the instrument’s intonation, comfort, and expressive capability. Unlike metal frets on Western instruments, the frets on Tar and Setar are movable gut or nylon ties that directly shape the microtonal intervals of Persian music. Over time, these frets may loosen, shift, or wear out, and proper replacement ensures the instrument continues to perform at its best.

This updated guide provides a precise, instrument‑specific method for replacing Pardeh, correcting several common misconceptions found in general “fret replacement” tutorials. It also explains when frets should be replaced, how they are tied, and how their placement affects tuning and Persian intervals.

What Are Tar and Setar Frets (Pardeh)?

In Persian instruments, Pardeh refers to movable tied frets made from gut or nylon. Their placement defines the microtonal intervals of the dastgāh system — including neutral seconds, quarter tones, and other non‑equal‑tempered intervals.

Unlike fixed metal frets:

• Pardeh must be adjustable
• Their height affects playability
• Their position directly affects tuning and intonation
• Their material affects tone and feel

This guide focuses specifically on Tar and Setar frets, not Western frets.

Tools and Materials Needed

Use tools appropriate for Persian instruments — not generic guitar fret tools.

When Should Frets Be Replaced?

Replace or adjust frets when:

• They slip during playing
• They produce buzzing
• Their height becomes uneven
• Their position drifts and intonation changes
• They become frayed or flattened
• You hear inconsistent tone across strings

If multiple frets are unstable, a full re‑tying is recommended.

Step 1: Remove the Old Frets

Loosen the strings. Untie or cut the frets. Clean the neck.

Step 2: Prepare the New Frets

Correct Length (Important Correction)

The common “3–4× circumference” rule is not reliable. Instead:

• Measure the neck circumference at each fret position
• Add enough length for 2–3 wraps plus knotting

Material Preparation

Gut: soak briefly Nylon: no soaking

Step 3: Mark the Fret Positions (Pardeh‑bandi)

Tar and Setar do not use equal-tempered spacing. Their fret positions follow Persian intervals and instrument tradition.

Use:

• A trusted Pardeh chart
• Guidance from a luthier
• The instrument’s previous correct positions

Mark lightly with pencil.

Step 4: Tie the New Frets (Correct Method)

1. Position the Material

Place the string under the neck at the marked location.

2. First Knot (Anchor Knot)

Tie a secure anchor knot.

3. Wrap the Fret

Wrap the string around the neck:

• 2–3 wraps for Setar
• 3–4 wraps for Tar

Wraps must be tight, parallel, and without overlap.

4. Final Knot

Tie a second knot firmly.

5. Trim the Excess

Leave a short tail to prevent unraveling.

6. Align the Fret

Slide the fret gently until it sits perfectly on the marked position.

Step 5: Fine-Tuning, Testing, and Adjustments

Tune the instrument. Check intonation. Check stability. Ensure smooth surface (no sanding).

Tips for Success

Use high-quality gut or nylon. Keep wraps tight but safe. Always check intonation after tying. Avoid generic guitar fret advice. Consult a luthier for complex adjustments.

Common Issues and Troubleshooting

Frets Slipping → wraps too loose or knot weak Buzzing → uneven height or misalignment Incorrect Pitch → fret position inaccurate

Tar vs Setar Frets (Key Differences)

Tar: thicker neck, 3–4 wraps, slightly higher frets Setar: thinner neck, 2–3 wraps, lower frets Microtonal layout similar but not identical

FAQ: Can I Use Alternative Materials?

Some players experiment with fishing line or synthetic gut, but traditional gut or quality nylon is recommended.

Conclusion

Replacing the frets (Pardeh) on a Tar or Setar is a precise but approachable process when done with correct technique. By following this instrument‑specific guide — and using the accompanying video tutorial — you can ensure accurate intonation, stable frets, and the expressive microtonal character that defines Persian music.

Proper fret maintenance preserves the unique voice of Tar and Setar, whether you are a beginner or an experienced musician.
