Course (music)

The strings in each multiple-string course are typically tuned in unison or an octave.

A typical piano, for example, contains courses with one, two, and three strings, in different parts of its range.

There are also several patterns of modern ten-string guitar but all have ten single strings, played individually.

The courses are most often tuned E-A-D-G-B-E, similarly to a six-string guitar; however, older instruments were often tuned one tone lower D-G-C-F-A-D to reduce the tension on the neck, and commonly played with a capo on fret 2.

The electric twelve-string bass has twelve strings in four triple courses.
