班卓琴调音指南
Open G调音（5弦班卓琴的标准调音）
Open G调音（gDGBD）是蓝草和大多数5弦班卓琴风格的标准调音。从第5弦到第1弦：g（短第5弦上的高G4，392 Hz）、D3（146.83 Hz）、G3（196 Hz）、B3（246.94 Hz）、D4（293.66 Hz）。这种调音在开放弹奏时形成G大调和弦，使经典的滚奏和基于无人机的旋律成为可能。

Banjo Tuning Tips
- 5th string first – Tune the short 5th string (high g) first as a reference point
- Use light touch – Banjo strings are thin; small peg adjustments make big pitch changes
- Let head settle – New banjo heads stretch, causing tuning drift for 1-2 weeks
- Check bridge position – Misaligned bridges cause intonation issues, not tuning problems
- Tune before playing – Banjos are sensitive to temperature; retune when moving between rooms
Understanding Banjo String Numbering
Banjo string numbering is unique: the 5th string is the SHORT string nearest your face, tuned to high G. Strings 4-1 run from low to high (D-G-B-D in Open G). The 5th string acts as a drone and is rarely fretted, giving banjo its distinctive sound.
Clawhammer vs Bluegrass Tuning
Both clawhammer and bluegrass banjo typically use Open G tuning. However, clawhammer players often explore alternate tunings like Double C, G Modal, or Drop C (gCGCD) for specific songs. Bluegrass players stick with Open G for 95% of playing, occasionally using D tuning for fiddle tune keys.
When to Change Banjo Strings
Change banjo strings when they lose brightness, won't hold tune, or show visible wear. Phosphor bronze and stainless steel strings last 2-3 months with regular playing. The 1st string (D) breaks most often and should be replaced immediately—keeping spares is essential for performers.
