Tenor Banjo Information
The Tenor Banjo is used extensively in both Irish traditional music, and Traditional Jazz. It has a shorter scale than the G Banjo, and 4 strings tuned CGDA, but it is common for Irish musicians to retune down to GDAE using thicker strings. Used in jazz and popular music earlier this century the tenor banjo has 4 strings and is usually tuned CGDA.

The Irish and Scottish traditional players put heavier guage strings on them and tune them down to GDAE, an octave below mandolin, fiddle etc.

They also favour instruments with a shorter scale length (17 frets rather than 19) because it makes using the same fingering as the fiddle possible.

Tenor banjo should not be confused with plectrum style which was used much like the tenor but has a longer neck (22 frets) and a different tuning. Jazz players like the extra frets because they can use the same chord shapes and patterns in different positions.
