Ukulele Tunings:

Standard Tuning: (G, C, E, A) — Commonly used for all ukuleles other than the Baritone size. Unlike a guitar, not all of the tones get progressively higher. The first string, G, is higher than the C and E but lower than the A.

Linear/low 4th tuning: (low G, C, E, A) — A popular alternative tuning drops the first string to a low G so that the strings are in progression just as they are on guitars, violins, and most other popular stringed instruments.

Baritone Ukulele Tuning / G Tuning: (D, G, B, E) — This is the same as the tuning of the bottom 4 strings of a guitar, or the same as the strings of a bass guitar. This is the standard Baritone ukulele tuning but is also used with smaller ukuleles by some players, particularly by guitarists just learning the instrument.

Slack-key Tuning: (G, C, E, G) — Produces a C major scale when strumming the open strings.

English Tuning / D Tuning: (A, D, F#, B) — Popular alternative tuning for soprano ukuleles. This is the same as standard tuning, but every string is tuned a whole step higher. This makes playing different chords easy with the same fingering learned from standard tuning.

Canadian Tuning: (low A, D, F#, B) — Another popular alternative tuning for concert and tenor ukuleles, it is the same as English Tuning except that the A is tuned down an octave.
