Bass Standard Tuning (E-A-D-G)

4-string bass standard tuning, from the thickest string: E, A, D, G. It's the same as the bottom four guitar strings tuned one octave lower. Low E1 is about 41Hz — one octave below guitar's 6th string E2 (82Hz).

5-string bass adds a lower B0 (about 31Hz) for BEADG, giving deeper low end for metal and modern rock. 6-string adds a high C above G for BEADGC.

How to Tune Your Bass

Low frequencies can be tricky to detect. Keep these tips in mind.

1. Open the online tuner

Select 'Bass' in the SnapRhythm tuner. The pitch detection range switches automatically for low frequencies.

2. Let the note sustain

Short plucks can be hard to detect. Use a pick or fingers to sustain the note, and keep a reasonable distance from the mic.

3. Start with string 4 (E)

Begin with the thickest string. Tighten the peg to raise pitch, loosen to lower.

4. Recheck string tension balance

Adjusting one string affects the others. Go through all strings once more after finishing.

FAQ

What is standard bass tuning?
For 4-string bass, it's E1-A1-D2-G2 from string 4 to string 1. Same as the bottom four guitar strings, one octave lower.
How do I tune a 5-string bass?
Standard 5-string adds a low B0 (about 31Hz) as string 5. Full tuning: B-E-A-D-G. Used extensively in metal, R&B, and worship music.
Low notes are hard to detect — what do I do?
Low frequencies are tricky. Pluck the string strongly enough to sustain, and keep the mic at a moderate distance. Increasing mic sensitivity helps too.
Is there a Drop D tuning for bass?
Yes. String 4 E1 drops a whole step to D1 (about 37Hz). Useful for matching guitars in Drop D.
How often should I tune my bass?
Check tuning every time you start playing. New strings stretch and drop in pitch for weeks; temperature and humidity also affect tuning.
