Bass chord finder
Tap the frets of any shape on the neck, or pick the notes, and the finder names the chord: its usual name, the other names the same notes go by, and what each note is in it. Hear it, then see every way to play it. It works in any tuning.
Nothing you put in is kept or sent anywhere.
What chord is this? Common bass shapes and their names
The shapes bass players meet first, read by the finder: the frets from the lowest string to the highest (x is a string not played, 0 an open string).

How does the chord finder work?
It reads the notes the shape makes, from the lowest string up, and looks for the simplest chord they spell. Doubled notes do not change the chord. When the lowest note is not the root, the chord is written with a slash: C/E is C major with E in the bass.
Why can one shape have two names?
The same notes can be heard from different roots. 8779 is C6, C E G A, and the same four notes are Am/C. The finder lists the usual name first and the others after it; the music around a chord decides which name fits.
What do x and 0 mean?
x is a string you do not play, 0 a string played open. Type the frets from the lowest string to the highest.
Can it name chords in other tunings?
Yes. Choose a tuning above, such as Half step down, Whole step down, C standard, and the finder reads the notes of that tuning. The strings' names on the neck change with it.
What if it finds no chord?
Some groups of notes have no chord name: three notes side by side, for example. Take a note off or move one, and the finder names what is left.
Can I find a chord from its notes?
Choose From notes and pick them; the first is the lowest. C, E, G is C major; E, G, C is C/E.
