Questions & troubleshooting

What are the notes of Open D tuning?
Open D tuning on banjo is F♯ D F♯ A D, from the 5th string to the highest.
How do I tune to Open D from standard tuning?
Starting from standard (G D G B D): string 5 down a half step, string 3 down a half step, string 2 down a whole step. Every other string stays the same. Use the tuner above to check each string.
Is Open D tuning bad for my banjo?
No. Changing tuning is completely safe. Just tune gradually, and when raising pitch go slowly so you don't over-tighten a string. After a big change, the neck can take a day to settle, so check your tuning again.
