About the Bass Note Frequency Chart
Guitar Tool Hub's bass note frequency chart lists the fundamental frequency, in hertz, of every note on a bass guitar neck, from the open strings to the 24th fret. Choose any of 9 tunings for 4, 5 and 6-string bass, and the chart shows each note's name, octave and frequency at standard concert pitch (A4 = 440 Hz, equal temperament). Tap any note to hear its exact pitch as a sustained synthesized tone, and see its first 8 harmonics. That is handy for tuning, EQ and mixing, and for understanding why a bass sounds the way it does.

Frequently Asked Questions
A 4-string bass in standard tuning runs from the open E at 41.20 Hz to about 392 Hz (G4) at the 24th fret of the G string. A 5-string adds the low B at 30.87 Hz, and a 6-string reaches about 523 Hz (C5) with its high C string. Those are fundamentals: each note also has harmonics at 2, 3, 4 times its frequency and up, which reach well into the kilohertz range.
In standard 4-string tuning: E1 41.20 Hz, A1 55.00 Hz, D2 73.42 Hz and G2 98.00 Hz. A 5-string adds B0 at 30.87 Hz below the E, and a 6-string adds C3 at 130.81 Hz above the G. All values are at standard concert pitch, A4 = 440 Hz.
Every fret raises the pitch by one semitone, which multiplies the frequency by the twelfth root of 2 (about 1.0595). Twelve frets double it, which is one octave. The chart uses equal temperament with A4 = 440 Hz, the tuning standard for modern instruments, so the 12th fret of the A string is exactly 110 Hz.
A plucked string vibrates at its fundamental frequency and at whole-number multiples of it, called harmonics or overtones. The 2nd harmonic is an octave up, the 3rd an octave and a 5th up, and so on. Small speakers cannot reproduce a bass's lowest fundamentals, so on a phone or laptop you mostly hear the harmonics, and your ear fills in the missing fundamental. Knowing them helps when you EQ a bass in a mix.
Yes. Pick any of 9 tunings: Standard 4-string, Drop D, half step down, full step down, Drop C, BEAD, Standard 5-string, 5-string high C and Standard 6-string. Every frequency on the chart updates for that tuning.
