42 tunings with step-by-step changes from standard, a mic tuner, reference tones, and a custom tuning builder.
B standard tuning is B E A D F♯ B, from the lowest (6th) string to the highest (1st). Compared with standard tuning, 6 strings change.
A fourth below standard, the usual tuning for a baritone guitar. On a normal guitar it needs a much heavier string set.
| String | Note | Frequency (A = 440 Hz) | Change |

Every string is 5 semitones lower than standard, so every chord, scale and riff you know works with the same fingers and sounds 5 semitones lower. An E shape sounds as B, A as E, D as A, G as D.
Singers often find a song easier a little lower, and the looser strings make bends and vibrato easier. Very low tunings also give a heavier, darker sound.
Starting from standard tuning: 6th string down 5 semitones to B; 5th string down 5 semitones to E; 4th string down 5 semitones to A; 3rd string down 5 semitones to D; 2nd string down 5 semitones to F#; 1st string down 5 semitones to B. Use the tuner at the top of this page for each changed string.
From the lowest string to the highest: B1, E2, A2, D3, F#3, B3 (B E A D F# B).
Reverse the changes: 6th string up 5 semitones to E; 5th string up 5 semitones to A; 4th string up 5 semitones to D; 3rd string up 5 semitones to G; 2nd string up 5 semitones to B; 1st string up 5 semitones to E.
Tuning down a lot makes strings slack, which can buzz. If it does, use a heavier string set or play a little lighter.
