What are the string notes for bass guitar tuning?
Standard tuning for 4 string bass guitar is E A D G - the same as the lowest-sounding strings of a six-string guitar, but an octave lower.
This goes from the 4th string (the thickest string) to the 1st string (the thinnest string)...
E - 4th string - Thickest string - Lowest note
A - 3th string
D - 2nd string
G - 1st string - Thinnest string - Highest note
