The standard tuning of a 7-string jazz guitar is typically tuned in fourths, with the lowest string being tuned to a low B, followed by E, A, D, G, B, and E. This tuning is commonly referred to as “B standard” tuning and is often used by jazz guitarists who want to expand the range of their instrument.
This tuning allows guitarists to play lower notes than a standard six-string guitar, which can be useful for playing bass lines or providing a thicker, more complex harmonic foundation for a jazz ensemble. It also allows guitarists to play higher notes than a six-string guitar, which can be useful for soloing and playing melodies in the higher registers of the instrument.
There are, of course, variations on this tuning that some jazz guitarists may use. Some guitarists may tune their seventh string to a C rather than a B, creating a tuning known as “A standard” tuning. Others may tune their seventh string to an A, creating a tuning known as “B flat standard” tuning. These variations can provide slightly different tonal possibilities and can be used to achieve different effects in a jazz context.
It is worth noting that while this tuning is commonly used by jazz guitarists, it is not the only option. Some guitarists may choose to tune their 7-string guitar in other ways, such as using a combination of fourths and thirds, or tuning their lowest string to a different note entirely. Ultimately, the choice of tuning will depend on the individual guitarist’s preferences and the specific musical context in which they are playing.
