How to use the bass tuning chart

  1. Choose the tuning and string count for your bass.
  2. Start with the thickest string, shown first in each chart row.
  3. Pluck the string cleanly and compare it with the target note in the online bass tuner.
  4. Turn the tuning peg slowly until the pitch indicator is centered.
  5. Repeat for every string, then check them all again because neck tension can shift slightly.

Choosing a bass tuning

Standard tuning keeps familiar scale and chord shapes and works across nearly every style.

Drop tunings lower the thickest string for added range and easier one-fret power shapes.

Very low tunings may need heavier strings and a setup to keep tension, intonation, and clarity under control.
